In this How to Grow Cannabis article, Growers Network covers some technical terms you should know if you want to sound like professional talking about your plants’ flowers.


In a few of our previous “How to Grow Cannabis” articles, we talked about propagating your plants and genetics through seeds. Today we’re going to walk through some of the basics of sexual reproduction in plants to see how we get to those seeds -- and potentially even make some of your own.

For this article, we’ll be focusing primarily on Cannabis plants, which are Angiosperms, or flowering plants. Cannabis can be male, female, or hermaphroditic. As a grower, it’s generally best to have female-only plants. As a breeder, you may want both sexes, or you may want all three, depending on your needs.


Terms


Like any good science, there are all sorts of terms involved in plant reproduction. Let’s go over the important ones and explain what they are.

General Terms

  1. Dioecious: A plant species that exclusively has male or female plants on individuals. Plants from dioecious species do not contain hermaphrodites. Cannabis is not dioecious. Pronounced as “Dye-eesh-us”
  2. Flower: The reproductive structure of a flowering plant. Flowers can contain male parts, female parts, or both. In Cannabis, the flower can also be called the “Cola
  3. Hermaphrodite (Abbrev: Herm): A plant that exhibits both male and female body parts, typically in the same flower. In Cannabis, hermaphroditic plants typically arise in a response to unusual stressors in their environment. There are a variety of different terms that can refer to this condition, although historically this is the most common one. Here are a few other terms that refer to the same thing:
    1. Bisexual
    2. Androgynous
    3. Monoclinous
    4. Synoecious
  4. Monoecious: A plant species whose flowers contain both male and female parts. Cannabis is not monoecious. Pronounced as “Mon-o-eesh-us”
  5. Subdioecious: A plant that is typically dioecious, but sometimes exhibits hermaphroditic flowers under certain circumstances. Cannabis is subdioecious.

Flower Parts

  1. Anther: The portion of the male stamen that produces pollen.
  2. Carpel: The female portion of the flower. Contains the ovary, stigma, and style. Sometimes called the pistil or the gynoecium.
  3. Calyx: Sepals that have fused together. Cannabis typically has calyces, not sepals, and the calyces are where a majority of the trichomes are found.
  4. Corolla: All petals of a flower are called the corolla.
  5. Ovary: The larger female structure holding ovules and connecting to the style and stigma.
  6. Ovule: Individual eggs held in the female portion of the flower.
  7. Perianth: A term used to describe both corolla and calyx combined.
  8. Petal: The colorful portion of a flower designed to attract pollinators.
  9. Sepal: Sepals are leaves underneath the petals. They are typically green. Their main role is to protect the flower before it opens.
  10. Stamen: The male portion of a flower. Stamen is made up of the anther and stalk, and produces pollen. Typically looks like a thin filament with a bulbous end. In Cannabis, these look like grapes attached to a stem.
  11. Stigma: The female portion of a flower that collects pollen.
  12. Style: The “pollen tube” that connects the stigma to the ovaries.

Function


This seems relatively simple, right? Pollen combined with an ovary should result in a seed. And you’re correct!

But there’s a couple other things we should discuss when it comes to the sexual reproduction of Cannabis. For one thing, Cannabis is typically wind-pollinated. That means that neither mammals nor insects need to come along to spread pollen -- a simple breeze is sufficient. This is why you have to be careful to separate your male and females plants in the grow, because otherwise you’d get all sorts of crazy plant sex from simply having fans.

Another thing we should mention is that it’s not always apparent from the get-go which Cannabis plants are male and which plants are female. It’s only when the flowers start to form and you can see stamens or pistils that you can tell which plants are which. And if you have a hermaphroditic plant (exhibiting both male and female parts), you should go back through your notes and try to figure out why that’s happening.


Conclusion


We hope that helped clear up some confusion about reproduction in Cannabis. In a future article, we’ll go over the practical concerns of how to intentionally breed specific plants with each other and some of the tools you’ll need.

Keep your eyes peeled as we move into propagation!

What Lies Ahead for Cannabis

Ethan Kayes tells us about his vision for the future of the Cannabis Industry in this op-ed piece.

The following is an article produced by a contributing author. Growers Network does not endorse nor evaluate the claims of our contributors, nor do they influence our editorial process. We thank our contributors for their time and effort so we can continue our exclusive Growers Spotlight service.


Cannabis growers, we need to talk. The industry is changing rapidly, and as legalization comes knocking, the old ways of growing will not be viable any longer. Today, I see us on the cusp of the first big shake-out of growers. The next 12 to 18 months will be hell for people who can’t adapt.

We need to start acting like adults and treat Cannabis as a serious 9-to-5 business.


A Little History


Who am I to tell you this? Well, let me start by saying that I have never grown cannabis legally. I got my start by growing floriculture crops legally in large, commercial production facilities. I would go on to grow Cannabis illegally in a 3000 square foot grow room for 8 years. I never got caught and never ran into trouble. I avoided marijuana mitigation efforts by the state of Missouri. We grew and sold in bulk only, focusing on increasing the number of grams per plant.

During the farm crisis of the 1980s, I saw a lot of greenhouse growers knocked out of the market. Many hippies became land-rich and money-poor in no time. The smart ones shifted gears and focused on niche markets. I could list several hundred different growers who survived the crisis by specializing. What did these growers have in common? They could beat out the competition. They knew how to survive trying economic times by cost accounting. They were so familiar with cost accounting that they could tell you the cost of any crop by unit. We aren’t doing that yet in the cannabis industry, and it’s something we need to start doing.


The State of the Grow


Of course, cost accounting isn’t our only issue. There’s a host of other issues we need to resolve to be seen as a mature market. Here are some of the problems I see in today’s grows:

    1. Genetics

The genetics system we have in place currently is unreliable and inconsistent. We can’t even get our names right. Other agricultural industries can buy seeds of a particular cultivar by the thousands and have a thousand identical plants. And that’s by seed, not by clone.

As the market shifts, it’s very likely we’ll see fewer cultivars come out, but they’ll have more consistent genetics and behaviors. The companies that are producing these new cultivars will be movers and shakers in the industry.

    2. A Lack of Differentiated Market Segments

Market segmentation is a business term used to refer to targeted marketing. You focus on a particular audience or group of consumers (or multiple groups of consumers) to help make your product stand out. Right now, our industry is focusing either on broad swathes of society or very niche markets, missing out on significant marketing opportunities.

For example, flowers versus concentrates. The two require different approaches to growing, marketing, and accounting.

    3. Too Much Pseudoscience and “Woo”

The cannabis industry relies too much on anecdotal thinking and superstitious beliefs. That is not the sign of a mature industry, and growers who are able to use scientific literature will experience much greater, more reliable success.

    4. Inconsistent Growing Patterns and SOPs

We have not well-defined what makes a “great” plant, and in turn we haven’t determined the best ways to grow that “great” plant. Standardization helps reduce costs and improve quality, and growers with standardized processes will be incredibly competitive to those relying on their intuition alone.

    5. Failing to Treat Cannabis as a Commodity

This goes back to what I was describing in cost accounting. Currently, accounting is not the primary driver of a grow. Since we are in the business of growing, our accounting needs to support the grow. Not the other way around.


The Future of the Grow


In the next five years, we are going to see the good growers succeed and dominate the industry. These growers will generally fall into one of two groups: Big Cannabis and specialty growers. Both of these groups are going to face the same basic problems:

  1. They will need to determine the cost of a gram per square-foot-week. Whoever is able to drive the cost down will dominate their market segment.
    1. Big Cannabis will be in greenhouses for bulk flower and in the field for concentrates.
    2. Boutique growers will be able to persist with higher costs in indoor grow rooms and will have to charge higher prices for it. They will have more limited market segments.
  2. Growers will need to make the switch from vegetative cloning to F1 seeds. This will be a huge shift for the industry, but seeds will lower production costs and control viral diseases, massive advantages that cannot be ignored.
  3. Standardization of growing practices and cost accounting will become primary business drivers. End-to-end cost accounting will rule the grow.
  4. Artificial lighting will sort itself out. Only a few specialty lighting companies will remain, and they will let the grows define the spectrum for each phase of the grow.
  5. Environmental controls will become simpler. Greenhouse-specific controls will have to match the market pressure of cheaper office and home environmental controls as the margins for Cannabis begin to slim.
  6. Growers using synthetics will have an economic advantage over organic growers. Organic growers will need to start marketing like they are the “Whole Foods” of cannabis and appeal to consumers.


Conclusion


Right now we stand on a precipice. We have a lot of great opportunities as growers, but we’re also looking at lots of challenges in the near-future. The cautious, science-based growers who have a strong emphasis on R&D and good accounting are going to win.

From the voices in my head.

You friend in growing,

Ethan

How Cannabis Has Affected Culture: Religion

Do you want to be part of our private, professional community?

Growers Network explores the facets of cannabis use as they pertain to religions around the world. What do different world religions have to say of one of the most ancient of drugs?


Today’s topic may not make for polite dinner conversation, but it’s an important one to have around the subject of cannabis’ effects on culture. Few things affect people’s underlying philosophies like their religions do. So how has cannabis influenced those religions? Let’s take a look, and I’ll try to break it down by major religions.

Author’s Note: A caveat is that there are a lot of religions in the world. In this article I will attempt to focus on the largest religions (the Abrahamic faiths, Hinduism, Buddhism) and a few other notable ones such as Rastafarianism. I shall try my best to be as objective as possible.


The Abrahamic Faiths


We’ll start this piece off with the religions that the majority of the world’s population believes in. Many studies and surveys place the total percentage of believers in Abrahamic faiths (Judaism, Christianity, Islam) at around 55 to 56% of the total world’s population. That’s a lot of believers, so let’s get a little more specific and delineate their views:


Judaism

Cannabis did not serve a major role in Judaism, and it is almost never mentioned, with one notable exception: the materials used to make traditional “holy anointing oil.” Holy anointing oil was used by priests and rabbis for various rituals, and was forbidden to common folk. In order to make holy anointing oil in the Jewish faith, you needed the following ingredients:

  • 6 kg parts pure myrrh (a kind of tree resin)
  • 3 kg part sweet cinnamon
  • 3 kg part “Kaneh Bosem”
  • 6 kg parts Cassia (another variety of cinnamon)
  • About 4 liters of olive oil

Notice that third ingredient? “Kaneh Bosem”? This is where the contention lies, because Kaneh Bosem is not defined particularly well and is the subject of debate amongst Jewish scholars. Some speculate that this may refer to sweet cane, some think it is rosha grass, and few have suggested cannabis in the form of hemp. Because Judaism is such an old religion, translation and time have led to confusion over what “Kaneh Bosem” refers to.

Either way, this is the only possible reference to cannabis in the Hebrew Bible, and the only things that seem to get smoked are animal meats.


Christianity

Christianity, like Judaism, did not generally refer to cannabis in its holy texts. However, there is a general consensus in most Christian denominations that cannabis falls under the purview of “intoxicants.” The Christian Bible generally refers to “wine” as being intoxicating, and several denominations have since expanded the list of intoxicants to include cannabis.

Of note amongst the different denominations, the Church of Jesus Christ of Latter Day Saints (LDS, or Mormons as they are colloquially known) prohibits almost all intoxicating substances, but does grant exclusions for non-intoxicating derivatives such as non-psychoactive cannabis.

Catholic popes have generally spoken against cannabis, and while Protestantism features no central authority, most large Protestant groups view cannabis use in a negative light.


Islam

The Quran does not say anything explicitly about cannabis, but most Islamic scholars view cannabis as an intoxicant, and thus haram (forbidden). Matter settled, right?

Well, not exactly. See, a lot of the countries that are majority Muslim are also where cannabis grows naturally (and likely originated), and it has become part of their culture. Hashish is historically Middle-Eastern, with origins tracing back to Afghanistan, Iran, and Pakistan. Afghanistan is still one of the largest hash producers, and it’s a majority-Muslim country. Same goes for Morocco and Turkey -- cannabis predates Islam, and remains a major cultural symbol. Prohbtd did an excellent piece on this seeming contradiction, and you can read about it here.


Special Case: Rastafarianism

Rastafarianism is considered an Abrahamic faith, and while the number of adherents are relatively small compared to other religions, it is worth mentioning the role that cannabis plays in Rastafarianism. For the Rasta, cannabis is a sacred herb, and ingestion brings them closer to Jah, or God. While cannabis use is not necessary to be a Rasta, many do partake.

Rastas point to Genesis 1:29, Psalms 18:8, and Revelation 22:2 as specific references to cannabis in the Bible, and treat cannabis as the herb to “heal the nations.”

If you would like to read more about the specific spiritual traditions of Rastafarianism and cannabis, you can read about them here.


Eastern Faiths

Lest we be too Eurocentric, there are faiths of very significant size in India and China, as well as the rest of Asia and the Pacific Islands. Of particular note in the Eastern Hemisphere are Hinduism, Buddhism, Sikhism and Chinese Folk Religion (including Taoism) due to their large number of adherents. Let’s dive in!


Hinduism

In Hinduism, Bhang is a traditional beverage made of ground-up cannabis flowers and various spices, and is traditionally served during the festival of Holi. The act of drinking bhang is supposed to cleanse the body of sins.

In traditional Hindu lore, cannabis is directly associated with the god Shiva, and is considered one of the five most holy plants in the Atharva Veda. There are multiple differing stories about how Shiva is associated with cannabis, but all of them depict cannabis as a rejuvenating and cleansing plant. Many ayurvedic texts (early Indian medicinal books) recommend cannabis as a treatment for pain or as an aphrodisiac, but only in small quantities.

A typical depiction of Shiva. Notice anything about the leaves?

Cannabis is also referred to in several other Hindu holy scripts, including Dhanvantari Nighantu, Sarngandhara Samhita, and Kayyadeva Nighantu. Just in case you’re interested.


Buddhism

In Buddhist traditions, the five precepts, or five rules of training, are the underpinnings of Buddhist morality and constitute its code of ethics:

  • The first precept is against the taking of life unnecessarily.
  • The second precept prohibits theft.
  • The third precept condemns adultery.
  • The fourth precept preaches against lying or false speech.
  • The fifth precept (and the most relevant one to us) prohibits intoxication.

The fifth precept is the most important in our discussion. Some practitioners believe that the fifth precept is meant to apply specifically to alcohol, but others believe it also applies to any drug or narcotic as well.

Additionally, after I spoke with a few Buddhists, it became clear that every precept may have exceptions depending on circumstance. If an action does more good than harm, it may be an exception to the precepts. For example, if cannabis is used to resolve a medical issue and not just get high, then it is an exception to the fifth precept. Cannabis is part of traditional Buddhist medicines, so there are established exceptions in place for it.


Sikhism

Some Sikhs celebrate the festival of Holi like Hindus do, and consume Bhang as well. However, the first Sikh guru stated that any mind-altering substance was forbidden, including cannabis.


Chinese Folk Religions

Chinese folk religions include a wide swathe of different religious beliefs, including Taoism and Confucianism.

Editor’s Note: Please note that there is a large amount of variation in traditional Chinese religions, and they don’t always agree on certain subjects.

Cannabis has been traditionally grown in China for thousands of years, and is considered an important part of agriculture in the region. Its fiber was used for rope and bow strings, and it is prescribed in many traditional Chinese texts as part of medicinal formulations.

Traditional Chinese medicines focus on the equilibrium of Yin and Yang (feminine and masculine, respectively). Cannabis was associated with Yin (femininity) because of the fact that female cannabis plants are more productive than male ones. As such, it was used to treat menstruation, gout, rheumatism, malaria, absentmindedness (Probably didn’t help with that!), and more. Later Chinese doctors would use cannabis as an anesthetic.

Certain sects of Taoism also used cannabis as part of the incense in their traditions, providing hallucinogenic properties to various rituals. There is even a Tao deity named “Magu” whose name is literally translated as “hemp maiden.” She is a symbol of longevity and womanhood in this lore.


Special Cases


There are a few religions that are worth a special mention because of their relationship with cannabis. While the number of adherents to these religions is quite low compared to the other religions we have mentioned in this article, we might as well mention them because of their strong emphasis on cannabis:


”Paganism”

Paganism is a very loose term applied to any non-Abrahamic faith. In the context of this article, we are referring to European paganism, and most specifically Germanic Paganism.

There is archaeological evidence in some sites around Norway and Germany that cannabis (typically referred to as hemp) was used in rituals relating to the goddess Freya, the goddess of love, war, and death. We also know that the Vikings used hemp frequently as part of the cordage to sail in their ships, as it was superior to the bast fiber they had been using prior, and hemp was highly valued amongst Vikings for this reason.

Some research I found suggested that cannabis was involved in a fertility ritual in Germanic Paganism, but I could not find an original source to back this claim.


Conclusion


Phew! I hope that brief spiritual lesson was enough to make you want to go smoke a bowl. Either way, let us know your thoughts about this kind of article in the survey below, or in the discussion on the forum!

How Cannabis Has Affected Culture: Music

Do you want to be part of our private, professional community?
Join Now

It has often been said that without drugs, music would be a lot more boring. It’s not uncommon to hear about drugs and rock and roll in the same sentence. But what role has cannabis played in all this? Today, Growers Network looks through some records and finds what we can trace back to cannabis.


Blues


We’ll start today’s article with the Blues, the musical origin of many different kinds of music. The Blues originated in the postpartum American South, and developed from African-American spirituals and chants about struggles and discrimination. In the United States, cannabis has been stereotypically associated with African-Americans and Mexican immigrants, and some singers and songwriters played this association up. Here’s a piece from Ella Fitzgerald about how she dealt with struggles in her life:

Because Blues started in poor regions of the American South, recordings of early Blues music are generally rare, so it’s somewhat more difficult to track the role cannabis played in some of this music. However, references to it do appear from time to time in songs like “I’m Gonna Get High” (1937), “We Gonna Get High Together” (1938), and “Weed Head Woman” (1941).


Jazz


Jazz was directly affected by the Blues, and originated around the same time. Unlike the Blues, however, Jazz is manic in its style, often with free melodies, and a wider variety of instruments. Where Blues has a relatively strict structure, Jazz does not. However, like the Blues, Jazz musicians referenced cannabis in many of their songs, and nowhere is this more obvious in songs referencing “reefer.”

Some other older Jazz songs that reference Cannabis are “Jack I’m Mellow” (1922), “The Man From Harlem” (1932), and “All the Jive is Gone” (1936). Famous Jazz musicians such as Louis Armstrong were noted as lifelong users of cannabis.

Unfortunately, the Marihuana (sic) Tax Act of 1937 effectively made cannabis illegal, but cannabis would continue to remain in musical minds regardless of its legal status.


Reggae & Ska


Over in Jamaica, cannabis culture was alive and well thanks to the Rastafari. And nowhere else is it clearer that cannabis has had a serious impact on music than reggae and ska, which originated out of Jamaica. Bob Marley, one of the most famous reggae musicians, is often considered an international symbol representing cannabis.

The religion of Rastafari celebrates cannabis as a holy herb and uses it in a variety of different religious rituals. As a result, it affects many aspects of culture in Jamaica, including reggae.


Rock & Roll


Some of the earliest rock-and-roll musicians, the Beatles, were known to be big fans of cannabis use. Much of their music contained hidden references to cannabis, and when they wanted to go smoke a joint, they would use the expression “Let’s have a laugh!” And of course, they could use a little help from “a friend.”


Really changes the meaning of the song, doesn’t it?

Paul McCartney, the bassist for the Beatles would go on to have his own solo career, and referenced cannabis in several of his solo songs, including the song “Hi, Hi, Hi”. Many other influential rock and roll bands such as Pink Floyd, Jimi Hendrix, Bob Dylan, Aerosmith, Black Sabbath, and more would reference cannabis from time to time in their songs.


Hip-Hop & Rap


Hip-hop music originated out of blues, reggae, and rock in the 70s, and also inherited their love for cannabis. Needless to say, plenty of hip-hop music contains references to cannabis. Some of this music could get pretty raunchy, and because we try to stay professional, we’ll avoid linking anything too negative or rude. Instead, here’s a positive take on cannabis:

Rap and Hip-Hop are sometimes used interchangeably, but rap is only sometimes included in hip-hop music. Regardless, rap music carries on hip-hop’s tradition of referencing cannabis to this day.


A Clear Influence


From my time looking at some of the history of 19th and 20th century music, it’s pretty clear that cannabis has had a strong influence on major musicians. While not every band consumed, many prominent musicians and music styles would have been very different without the effects of cannabis.

Common Terms in the Hemp and Marijuana Industries

Do you want to be part of our private, professional community?
Join Now

Have you ever been confused by some of the terms used by Cannabis experts? Don’t worry, you’re not alone. Growers Network is here to help.


Every profession, industry, or hobby has its own technical jargon. This jargon can often confuse the general populace because it may use terms with entirely different meanings. For example, a scientific “theory” is completely different from the usage of “theory” in common parlance. A scientific theory is considered the most rigorous scientific understanding of a given subject, but in common usage it means what scientists would consider a hypothesis.

The Cannabis industry is no exception to this principle, and as such uses many terms that may be misconstrued or confusing to people who are not “in the know.” Because Growers Network is dedicated to educating both the Cannabis industry, we wanted to take this time to help educate the general public about these terms. All terms listed here are available in our glossary, or will be added to our glossary. If you would like to skip to any section, click on the links below:

  1. Biology
  2. Chemistry
  3. Consumption
  4. Cultivation
  5. Processing

Biology


    CB1 / CB2 Receptors

The CB1 and CB2 receptors are receptors found in the signalling pathways in the human body that are responsible for picking up different cannabinoids. CBD and THC often interact directly with these receptors.

    Endocannabinoid System

The endocannabinoid system is a signalling system found within most animals and is responsible for the regulation of a variety of different hormones and chemical signals. In humans, the endocannabinoid system is what Cannabis acts upon, altering its normal behavior.

    Indica / Sativa / Ruderalis / Hybrid

Indicas, Sativas, and Ruderalis refer to different subspecies of Cannabis, found natively in different regions of the world. Each type has its own unique properties associated with it. Hybrids are a combination of these different subspecies.

    Hemp / Marijuana / Cannabis

Each of these terms refers to the genus Cannabis. Hemp and marijuana are just different names for the same thing. Industrial hemp, however, refers to something specific. Industrial hemp is Cannabis that contains 0.3% THC or less, and thus cannot used for recreational purposes.


Chemistry


    Cannabinoids

Cannabinoids are a group of compounds that can be found in Cannabis and in the human endocannabinoid system. There are a large number of different cannabinoids, and they are often written in their abbreviated form.

Note: Every single cannabinoid has an “acid” precursor form. These acid precursors are produced by the plant, and are converted into their non-acid form in a process known as decarboxylation, which we will describe later. Acid precursors have their abbreviation appended with an “-A” or “A.” (IE: THCA / THC-A, CBDA / CBD-A)

  • Tetrahydrocannabinol (Abbrev: THC)
    1. THC is the primary psychoactive compound in Cannabis.
  • Cannabidiol (Abbrev: CBD)
    1. CBD is valued for several medical properties, and is non-psychoactive.
  • Cannabinol (Abbrev: CBN)
  • Cannabigerol (Abbrev: CBG)
  • Cannabichromene (Abbrev: CBC)
  • Cannabicyclol (Abbrev: CBL)
  • Cannabivarin (Abbrev: CBV)
  • Cannabielsoin (Abbrev: CBE)
  • Cannabicitran (Abbrev: CBT)
  • Tetrahydrocannabivarin (Abbrev: THCV)

It is very likely more cannabinoids will be discovered in the feature, so keep an eye out for any abbreviation that begins with “CB.” There are also less-common cannabinoids which are isomers of other molecules, such as THC-8.

    Decarboxylation / Decarb

Decarboxylation is a chemical process that relies upon heat (often from smoking or cooking) to cause a carboxylic acid group to leave the cannabinoid. This is how the acid forms of cannabinoids are converted into their non-acid forms. For example, THCA is converted to THC by decarboxylation.

    Terpenes

Terpenes are a group of chemical compounds found in nearly all plant life on Earth, with Cannabis being no exception. Terpenes are responsible for the wide variety of smells and flavors associated with different Cannabis strains.


Consumption


    Bong / Bowl / Water Pipe

A bong or “water pipe” is one method of consumption that essentially acts like a hookah, but for Cannabis. Ground-up Cannabis is placed into a bowl, which is then heated and the smoke is pulled through the apparatus by the user’s lungs. Thus, it is sometimes called “smoking a bowl.”

    Dabbing and Nails

Dabbing is a consumption method for Cannabis that uses concentrates instead of flower. Dabbing uses a “dab rig” that appears similar to a bong, but with a few key differences:

  • A “nail” typically is composed of titanium, quartz, ceramics, or glass. Nails that are made of quartz are sometimes called “bangers”
  • A “cap” to allow the accumulation of smoke (sometimes called a “carb cap” because it acts like a carburetor)
    Edibles

Edibles are a large variety of different foods that are created using Cannabis concentrates. Generally edibles are made using infused sugar, infused oil, or infused butter. A small list of edibles includes:

  • Gummies / Lollipops / Taffy / Candy
  • Brownies / Baked Goods
  • Sodas / Drinks (such as Bhang)
  • Cannaoil or Cannabutter mixed in with other food items such as popcorn or salad dressing.
    Joint / Spliff / Doobie / Marijuana Cigarette

Possibly the oldest form of Cannabis consumption, a joint is simply ground-up Cannabis flower rolled with a rolling paper into the shape of a cigarette. The joint is then lit on the opposite end and inhaled.

    Pipe

Probably one of the oldest forms of consumption, besides a joint, is a good old pipe. Ground-up Cannabis is placed inside of it, and heated up. The user then inhales. Pipes are typically made of glass or ceramics, but can be made with other heat-resistant materials.

    Tinctures

Tinctures is a term used to refer to cannabis extracts/concentrates that are typically delivered under the tongue (sublingually) or in a mucous membrane via an eyedropper. Tinctures are intended to be a fast delivery method without smoking.

    Topicals / Transdermals

Topicals and transdermals are consumption methods that use a lotion or patch to apply the cannabinoids to your skin. This delivery method is slower and less efficient than other delivery methods, but its effects are longer-lasting and subtler.

    Vape / Vaporizer / Vape Pen / Vape Cartridge

A vape, vaporizer, or vape pen is a convenient method of consumption that takes a vape cartridge full of concentrate or extract and heats it up with a small coil. The vaporized contents are then inhaled by the user.

This method of consumption is very common, due to the small size of vape pens and the ease of usage.


Cultivation


    Aeroponics

Aeroponics is a hydroponic cultivation method where the plant’s roots are suspended in air and sprayed regularly with a fine mist of nutrient solution. Unlike other hydroponic methods, aeroponically grown plants do not have their roots suspended in water.

    Buds / Nugg / Nugget / Flower

Buds and Nuggs are used to refer to the Cannabis flower. Unlike other flowering plants, Cannabis flowers are dense and concentrated, making them resemble little gold nuggets or chicken nuggets.

    ”Feminized” Seeds

Feminized seeds are female seeds that have been separated from male seeds. This can be done using genetic testing. Cannabis as a plant can be male, female, or both (sometimes called “herms”), and female plants are the most productive of the sexes. As a result, most growers seek out feminized seeds.

    Flowering

Flowering is a late stage in the life cycle of Cannabis. It is the stage where buds become dense, trichomes start appearing with greater frequency, and the Cannabis plant begins to prepare for reproduction. After flowering, Cannabis plants will die.

    Geoponics

Geoponics, as opposed to hydroponics, is a conventional growing method using soil.

    Hydroponics

Hydroponics is a growing method that does not rely upon traditional soil. Plants can be grown in a variety of inert mediums (or media) and fed a steady diet of nutrient water. There are different methods to feed the plants, including ebb-and-flow, aeroponics, deep water culture, and more.

    Integrated Pest Management (IPM)

Integrated Pest Management is a pest control strategy that focuses on preventative and proactive techniques, rather than reactive pest control. For example, a common problem in indoor and greenhouse grows is powdery mildew. Many growers will add fans and increase the airflow in the grow to prevent the formation of powdery mildew. This would be considered an IPM approach.

    Medium

The “medium” is the substance in which the plants roots are held. This can be traditional soil, coco coir, rockwool, clay, sand, pebbles, or other solid media. Every growing media has its own perks and drawbacks, and many growers will have a preferred medium.

    ”Mother” Plants

Mother plants, known as stock plants in the horticultural world, are Cannabis plants that are kept permanently in a vegetative state in order for growers to take cuttings from them. These mother plants serve as the genetic basis for the clones in a growing facility.

    Propagation

The propagation phase of a grow is the phase in which plants are either cloned or grown from seed. This is the most delicate phase of the grow.

    Strains

“Strains” is the current term used to refer to Cannabis cultivars. Each strain has a different set of traits and different chemical composition associated with it.

    Veg / Vegetative State

The vegetative state is the period in-between propagation and flowering. It is a period where the Cannabis plants have a sturdy root system and are growing steadily. The plants are not flowering during this period, and the plant is instead focusing on growth.


Processing


    ”Crystal”

Some isolates can be converted into a “crystalline” form. The most common crystals you’ll hear about will generally be THC crystals or CBD crystals. These crystals have a very high intensity, and should be treated with caution.

    ”Full-Spectrum” Extract

This is a special term used to refer to extracts that contain more than just cannabinoids, but also the majority of the cannabis’ terpene content.

    Isolates / Distillates / Extracts / Concentrates

All the terms above describe products that are made via a chemical extraction process. Essentially, these products remove the compounds we are really after from the plant material. Cannabis, like most plants, produces a variety of different chemical compounds necessary to support its structure and support life. These compounds are largely irrelevant to consumers and patients, and isolates, extracts, concentrates, and distillates separate the relevant compounds from the irrelevant ones.

    Wax / Shatter / Live Resin / Cherry Oil / Honey Oil / Rick Simpson Oil / Butane Hash Oil / Hash / Crumble / Rosin / CO2 Oil / Dab / Kief

Whoooooa Nelly that’s a lot of terms!

All the terms listed above are different kinds of extracts and concentrates. Most of the names for these extracts describe the physical appearance and characteristics of the concentrate. Some also describe how the extract is produced.

There are many more terms that I haven’t even included in this list. Some of the naming schemes may also vary by locality and preference.

    Rosin Press / Closed-Loop Extractor / Subcritical or Supercritical CO2 Extraction / Short-Loop or Short-Path Distillation / Vacuum Oven

These terms refer to some of the equipment and methods used to create the extracts and concentrates we mentioned above. Every extract listed above is produced with a different method.

How to Grow Cannabis 224 – Mendelian Genetics

Do you want to be part of our private, professional community?
Join Now

Today, Growers Network covers the basics of genetics and breeding for the caregiver level. If you remember your high school biology genetics pretty well, this article should be an easy read for you.


Hi everyone!

Today we’ll be talking about some basic genetics and reproduction topics in plants. We’re covering these topics because we can’t assume where are our readers are at in their understanding of botany, and it’s better to make sure that everyone is starting at the same baseline than assuming and accidentally leaving people behind. So let’s get into basic botanical genetics and reproduction!


Mendelian Genetics


Most of you who have attended a high school biology class should be familiar with the name “Gregor Mendel.” Gregor Mendel was a Catholic friar and abbott who is now famous for his work with pea plants. His work was originally discarded due to being so mundane, but we now understand him as the father of modern genetics. Genes that follow the principles he discovered are referred to as “Mendelian” in honor of him.

So what is a gene? Well, in its simplest form, a gene is a hereditary component that codes for a specific trait, protein, or modification in an organism. That might seem super specific, but it actually becomes pretty difficult to define when you really dive into the weeds.

Regardless, in Mendel’s time, nobody knew a thing about DNA. All people knew was that traits were inherited from parents, and seemed to “blend”. It was commonly believed that children were just a “blend” of their parents genetics. But that’s not how genes actually work. Instead, genes work in an entirely different way, as Mendel discovered. Each gene component (called an allele) codes for a specific output, and both parents contribute one allele to their children, for a total of two alleles for any given gene. He used a variety of different traits to demonstrate this:

Each trait or gene that Mendel studied only had two “forms”, thus being the perfect model to work with. Mendel took meticulous notes and noticed that there were some unusual things happening:

  1. Children of the same parents exhibited a specific ratio of traits, regardless of the trait being studied.
  2. Certain traits seemed to “dominate” other, more “recessive” traits.
  3. Some parents bred “true,” resulting in completely identical children, but when those children crossbred, they could produce different traits.

Now, we’re going to throw a bunch of terms at the wall, and hope they stick for you. If you ever get confused, please feel free to refer back to this article, or to the glossary, where we plan to add these terms:

  • Phenotype: Phenotype is the set of traits that can be observed on the individual. Phenotype is determined by genotype (and in real-world cases, environment).
  • Genotype: Genotype is the underlying genetic code that results in the phenotype. Genotypes are not expressed, only phenotypes are expressed.
  • Allele: One of two or more variations on a specific gene.
  • Dominant: When one allele will preferentially express over another allele, the allele is said to be dominant. Dominant alleles are denoted with an uppercase letter (IE: R)
  • Recessive: When one allele will hide or recede before a dominant allele, that allele is said to be recessive. Recessive alleles are denoted with a lowercase letter (IE: r). Typically the letter used is the lowercase letter of the dominant allele.
  • Homozygous: An individual with two identical alleles for the same gene is homozygous for that gene. (IE: RR, or rr)
  • Heterozygous: An individual with two different alleles for the same gene is heterozygous for that gene. (IE Rr)
  • Codominant: If two alleles for the same gene are both dominant, they will blend together producing a mixed result. This is codominance. (IE: RZ)
  • Sex-linked: Some genes may behave differently depending on the sex of the individual. Such genes are said to be sex-linked. Typically, sex-linked alleles will appear more frequently in males.
  • P generation: The “parental” generation. The parental generation for genetic experiments is almost always a pure breeding variety, that would always produce the same outcome if it bred with itself.
  • F1 generation: The “filial one” generation are the offspring of the P generation.
  • F2 generation: The “filial two” generation are the offspring of the F1 generation.

This may seem like a lot to learn… and it is. So let’s go over a few real-world examples:


Example 1: Seed Color

One of the traits Mendel studied was seed color in peas. He determined that the dominant allele was Yellow (Y) seeds, and the recessive form was Green (y) seeds. When he bred two “true breeding” parents of each variety together (YY x yy), he would always get plants that were Yellow. These “true breeding” parents were homozygous for the Yellow and Green color seeds, respectively.

At first glance, the children of these “True Breeders” were always Yellow (the dominant allele), so it might seem that the recessive trait (Green) was gone. But when Mendel crossbred the children (F1 generation) with each other, the Green trait would return! The children of the F1 generation would have a 3:1 ratio of Yellow to Green seeds, respectively.

So what’s happening? It’s best if we visualize it with something we call a “Punnett Square:”

With the first cross, you can start to get a picture of what’s happening and why the F1 generation is all yellow. You can also start to get a sense of why the F2 generation has green peas showing up again. The dominant trait (Yellow) is overriding the recessive trait (Green) until one of the F2 generation is homozygous recessive (yy). The Green trait “skipped” a generation. The genotype of the F2 generation is 1 YY to 2 Yy to 1 yy.


Example 2: Blood Type

Now we’re going to get a little bit more complicated and introduce something Mendel did not study -- blood type! With blood type, we see codominance come onto the scene, and we now have three alleles and four blood types:

Blood Types

  • Type A
  • Type B
  • Type AB
  • Type O

Alleles for Blood Type:

  • IA
  • IB
  • i

You’ll notice something with blood type -- there are two dominant alleles, and one recessive allele. IA and IB are codominant. This means that if an individual has the alleles IA and IB, they will exhibit Type AB blood. If somebody has two i alleles (ii), they will exhibit Type O blood.

Just like with the peas, you can do Punnett squares for each allele as well.


Multiple Alleles


This is where it really starts to get complicated. As I’m sure everybody is aware, no one gene exists in isolation. Every individual is composed of multiple different genes, and Mendelian genetics and Punnett squares do allow for this.

Now we have to start thinking about how reproduction works. Every parent, regardless of their gender, donates half of their genes to their offspring. These genes are passed onto their offspring in the form of gametes, such as sperm and eggs. In order to cross multiple alleles, we have to think about what each gamete might be carrying. The genetics of any given gamete are random -- they will take a random allele from the parent.


Example: Seed Color and Shape

We’ll stick with the familiar trait of seed color and throw in a second trait: Seed shape. Seed shape has two alleles: Round (R) and wrinkled (r). We’ll cross two homozygous parents for our first Punnett square:

You may notice that every single gamete in this case is identical. This is because both parents were homozygous for their traits. But now if we cross the offspring together, we end up with an entirely different portrait:

Whooooo Nelly that was complicated. On either side of the Punnett Square, you can see the different possible gametes from the heterozygous parents. Each parent has four possible gametes, instead of the two from before! As our Punnett square grows, the math stops being simple and starts getting really weird. Phenotypically, 9 express yellow and round, 3 express yellow and wrinkled, 3 express green and round, and 1 expresses green and wrinkled. Genetically, the situation is even more complicated.

You can continue adding genes and alleles, but as you see, this can become very complicated very quickly. If you start throwing in codominant traits or sex-linked traits… you will have a very tough time.


Sex-Linked Traits


But wait, there’s more!

You see, males and females exhibit genetic differences. For example, in humans, men have a Y sex chromosome, and women have two X sex chromosomes. The Y chromosome in men often means that men only get one copy of a gene located on the X chromosome from their mother, because the father donates a Y chromosome. As a result, recessive sex-linked traits appear more commonly in men. One of the most obvious examples is red-green colorblindness, which is very common in male children, but rare in female children. Women can carry the allele for red-green colorblindness without being colorblind.

Say we cross a normal father (CY) with a carrier mother (Cc):

As you can see, men face a 50% chance of exhibiting R-G colorblindness, and women in this cross can only be normal or carriers. There is only one way for women to exhibit R-G colorblindness -- if their father is colorblind and their mother is a carrier or colorblind.


Conclusion

M&F Talent Cannabis Career Tip of the Month: Vetting Potential Employers

Do you want to be part of our private, professional community?
Join Now

As a leading industry recruiting agency, Mac & Fulton Talent Partners has an inside look at the challenges faced by job searchers in the cannabis space. To this end, M&F Talent takes great pride in helping professionals understand their place in this exciting new industry.

The following is an article produced by a contributing author. Growers Network does not endorse nor evaluate the claims of our contributors, nor do they influence our editorial process. We thank our contributors for their time and effort so we can continue our exclusive Growers Spotlight service.


On both personal and professional levels, the cannabis industry is an extremely exciting thing to be a part of. For many who work in cannabis, there is an inherent pride in helping shape the industry into something great, something to be proud of. Yet, as the entire market is comprised of startup businesses, there are many challenges that job seekers would likely not see in more established lines of work.

Due to the novelty of the cannabis job market, there is great deal of volatility in job security. This can be for any number of reasons, including an inherent lack of organization, a lack of proper capitalization, or even a lack of a proper business plan. Additionally, there are a good number of business owners and investors who have inflated plans of “getting rich quick” in the industry, treating it as though it’s a gold green rush, not a serious business.

As a result of the instability of the cannabis space, it is vital that job searchers vet their potential and future employers. Doing some preemptive research about a business can help people better understand what sort of company it is they may be working for. Similarly, approaching a job interview with a critical awareness of the market can be helpful to one’s chances of being hired. With any luck, extra precautions can save the job seeker some serious heartache and frustration.

With the above ideas in mind, here are some great avenues to explore in vetting potential cannabis industry employers:


1. Don’t be Afraid to Ask Tough Questions


An extremely effective way to avoid taking the wrong job in cannabis is to simply be upfront and forward during the interview process. This often means asking tough questions like: “Why did the last employee in this role leave?” or “What sort of turnover rates do you have?” While it may seem somewhat daunting to press a potential employer on these tough questions, the best employers should respect applicants for being upfront and honest. In the event that the potential employer seems agitated by your questions or tries to deflect, it's probably a warning sign that they have something to hide.

Editor’s Note: Don’t fall prey to asymmetric information. Being upfront during an interview establishes yourself as someone who should not be taken advantage of.


2. Talk to other Employees


After the initial interview phase, some of the more astute job searchers will ask to speak to other employees at a company in deciding if the business is a fit for them. With this inside information, applicants can get a feel for their potential co-workers, as well as the general morale of the workplace. Potential coworkers demeanors and beliefs should be pretty telling about the business as a whole.


3. Follow the Funding


A major theme seen amongst dissatisfied cannabis industry employees has to do with the funding behind an operation. Namely, the industry is plagued by startup business owners who cannot pay their employees on time, if at all.

As such, doing some internet sleuthing on the financial state of a potential employer is never a bad idea. In fact, prior to starting a job search, we often encourage candidates to research what cannabis companies have recently received funding. With this critical approach, job searchers can identify and focus on businesses who have ample liquidity to handle payroll.

One of the great things about using financial data to vet a company is that cannabis companies who have received funding have already been thoroughly vetted by their financiers, which says a good deal about their internal organization and business model. If they have a business model and organization that appeals to these standards, they should have their business in order.

How to Grow Cannabis 223 – Maintaining Your Genetics

Do you want to be part of our private, professional community?
Join Now

Now that you have your genetics, let’s go over how to keep a steady supply for regular use!


Hello caregivers! In our last few articles, we touched upon how to figure out the strains you want to grow and how to find them. In today’s article, we want to talk about maintaining your stock of strains so you won’t need to worry about obtaining them again!


Maintaining Your Mother(s)


You may have sometimes heard of growers talking about their “mother” plants or stock plants. What exactly are these plants?

Essentially a mother plant is a cannabis plant that has been kept in its vegetative state in order to help propagate new plants. This mother plant will serve as the source of the genetics in your grow. It is kept in a prolonged vegetative state in order to keep it constantly growing without worry of death.

You will want to keep your mother plants in a separate room or tent of their own, so as not to accidentally induce flowering in them. Your mother plants should always be kept on a vegetative lighting cycle (18 hours on, 6 hours off), and given the best care and nutrients that you can provide. Because these plants are intended to provide the clones for the rest of your grow, they should not be under any significant stress, as this can have very negative consequences down the line.

Some growers opt to maintain the same mother plants for years on end. We have heard of some mother plants persisting for 15+ years. While this might seem appealing to a grower so they don’t have to worry about replacing their mothers, we can’t advise this approach. Cannabis is an annual plant, and prolonging its life well past its normal expiration date could have negative consequences and place stress on the plant. It is advisable that you cycle your mothers out periodically once every 6 months to a year to prevent this from happening. Your next mother should be taken from one of the very best clones from your current mother.


Cloning


The vast majority of growers we’ve spoken with on Growers Network maintain their strain variety and genetics through the vegetative cloning process. Unlike cloning animals, which comes with a whole host of problems, cloning plants is relatively simple and can even occur naturally.

But first, some of you may be curious as to why we use cloning instead of seeds. The simple explanation is that seeds are the result of sexual reproduction, and sexual reproduction can result in significant genetic changes in your plants. These changes could be welcome or unwelcome, but every time you reproduce via seed, you are changing your genetic stock to something different.


How to Clone

In our 100s series, we briefly described the cloning process in general terms. Let’s get a little bit more specific. In order to take clones, we need to take cuttings from a “mother” or stock plant that will serve as the source of our genetics.

--- Step 0: Preparation for Cloning ---

The cloning process is time-sensitive, and speed and precision are of the utmost importance. Before you start taking cuttings, make sure you have all the materials you need and are in a place where you can focus on the task. Here are the materials you’ll want:

  • Personal Protective Equipment (PPE) including a face mask, goggles (or glasses), and gloves. We do not want stuff getting in our eyes or mouths.
  • A sharp scalpel or razor blade. Be sure to sanitize your cutting tool with alcohol before making a cut, then dry the cutting tool. You don’t want to contaminate the cutting with anything. Do not use scissors because they can crush sensitive xylem and phloem.
  • A rooting hormone of your pick. The hormone should have Indole-3-Butyric Acid (IBA) in it that will help the cutting take root.
  • A rooting media of your choice. Make sure your medium is prepared to receive the clones. Some medias such as rockwool require pH remediation prior to planting.
  • A cloning tray and dome to store the cutting in while it first takes root.
  • A spray bottle with water.
  • A clean, stainless steel, aluminum, or hard plastic table to work on.
  • A good office chair.

--- Step 1: Take a Cutting ---

To take a proper cutting, you want to cut just above the nearest node on your mother plant. You want to use a very sharp blade such as a scalpel to make the cut, and you want to completely sever the cutting with no dangling fibers. You should make the cut as smoothly and evenly as possible, and at a 45-60 degree angle. If the cutting has dangling fibers, you will want to toss it aside and start again. Always make sure that your blade is sharp!

--- Step 2: Dipping and Medium ---

Once you’ve taken a good cutting, quickly but gently dip it in rooting hormone so that the now exposed xylem and phloem on the bottom of the cutting have thorough exposure to the hormone. You should probably keep the rooting hormone in a separate container so that you don’t contaminate your hormones bottle.

From there, you will want to gently place the cutting with rooting hormone into the medium you chose to use, and then put the medium and cutting inside your cloning tray.

--- Step 3: Repeat Steps 1 and 2 Until Your Tray is Full ---

When you have filled up your tray with the cuttings, you are almost done! Give the little cuttings a gentle misting of water from your spray bottle to get them nice and wet, and then place the dome for the tray on top. We want to make sure the dome is very humid, so if you see any signs that the cuttings are drying out, give it another spray. If the cuttings dry out, they will die very quickly.

--- Step 4: Labeling and Storage ---

Now you want to take a piece of masking tape and put a label on your cloning tray with a pen or Sharpie. Clones of different strains can look identical, so we want to indicate what strain it is and the date when the cuttings were made.

From there, you’ll want to take your tray and dome into your propagation area, which should have T5 lights or LED lights. These lights are generally much gentler on cuttings, giving them time to take root after the cutting process. We are not in a hurry with our cuttings! Give them as much time as they need. Your rooting hormones should make the process faster and more likely to succeed, so it is worth investigating how good a rooting hormone is.


Seeds


“Hold on!” I hear you say. “I thought we were just using clones to maintain our genetics!”

And you’re mostly right. Clones are our ideal way of maintaining genetic regularity throughout our grows. However, mother plants and clones require continuous ongoing growth, and sometimes something bad may happen. There are many different ways a grow can go wrong. As is commonly expressed, “S*** happens!”

This is where seeds can come into play. Cannabis seeds tend to last a very long time before they start to lose some of their shelf life. As a backup plan in case something goes wrong, you should have a few seeds of each strain that you grow stored in a safe, cool, dry place. Some growers I’ve spoken with have said that their seeds have lasted decades, which is extremely useful as a backup plan in case something happens. This way, even if you lose your crop or your entire facility, you aren’t starting completely from scratch.

We’ll talk more about how to make your own seeds in our next How-to-Grow Cannabis article, where we discuss breeding, but for now know that they can be of great value in maintaining your genetic stock.


Conclusion

Now you should have a stable genetic stock and a backup plan in case anything goes wrong. You can start building your genetic portfolio and provide your patients and clients with everything they could want, and may even be able to sell some clones to other growers if they need them.

How to Grow Cannabis 222 – Sourcing Your Genetics

Do you want to be part of our private, professional community?
Join Now

In today’s relatively short How-to-Grow Cannabis article, Growers Network covers some different ways you can get genetics for your caregiving grow!


In our last article, we discussed how to select the genetics or strains you want. It takes research and planning to figure out your ideal set of strains, and now we need to determine the best methods for actually acquiring those genetics.

These are in no particular order, and you shouldn’t necessarily trust one over another. Use your best judgement to source your genetics -- don’t work with people who have shady practices and behaviors.


Genetics You Already Have

If you were growing with us for the 100s series of How-to-Grow Cannabis, you should already have some genetics available for you to use. We’ll go over details about how to grow your own seeds in a future article, and we briefly touched upon cloning in a previous article, although we’ll go into more detail in a future article.

Should you wish to continue growing in the future, we highly recommend you start storing seeds or maintaining your own cloning facility, which we will explain in a future article.


Someone You Know

Just because you know someone, it doesn’t necessarily mean that they are the most trustworthy person to get genetics from. However, working with someone you know does have the benefit of convenience and often a lower price (if any). If you know somebody who’s a grower, it’s worth checking in with them to see if they have the genetics you want, and if they’d be willing to give you some clones.


Nursery/Grow/Seed Bank

Depending on what state you live in, nurseries, grows, or seed banks may be able to sell you clones or seeds. These nurseries typically maintain a stock of mother plants that they’re able to reliably reproduce for consistent genetics. You might think this was a guarantee of a particular strain’s genetics, but genetic studies would tell you otherwise.

However, unlike many other sources, nurseries and grow sites should be able to reliably supply you with genetics when you need it, so it helps to establish good relationships with these groups if you can.


Online Store

You can purchase seeds online, and there are many websites to buy seeds from. There is no guarantee that the genetics are what the sellers claim they are, and you will have to worry about shipping concerns (depending on where you live, you could run into legal issues with shipping). Online stores have no guarantee of your desired genetics being in stock, but they do have a wider selection of genetics than a local nursery, and they offer the convenience of ordering from your own home..

You can check out Growers Network for professionals to find curated knowledge about local seed banks in your area! Apply today.

What is the Difference Between Hemp and Marijuana?

Do you want to be part of our private, professional community?
Join Now

A common misconception we see from the general populace is that Hemp and Marijuana are two entirely different things. Growers Network explains the difference.


If online Google searches are anything to go by, it seems like the general populace doesn’t know the difference between hemp and marijuana:

So let’s address the elephant in the room: Hemp, marijuana, and Cannabis are all different names for the same species of plant belonging to the Genus Cannabis. Cannabis, in all its different forms and different strain names, is the same species as hemp.

Once more: Hemp is the same species as Cannabis. Biologically there is no difference.


So why do people treat them differently?

Well, the simple answer is that the cannabis people use to smoke joints and get high off of has a slightly different chemical composition than industrial hemp. Cannabis that is grown for its flowers and buds typically has a high concentration of THCA, the acid precursor to THC. THC is short for Tetrahydrocannabinol, and is the primary psychoactive ingredient that gets users “high.” Generally these varieties of Cannabis have anywhere from 2% to 30% THC in them.

Hemp products, unlike smokeable Cannabis products, generally have less than 0.3% THC in them. This means that Hemp flowers/buds are virtually useless to anybody who is trying to get high off of them. You would have to burn a lot of these flowers to feel even a minute effect.

Unlike the early 1900s, we know which chemical is the source of the buzz, and governments around the world have recognized this fact. Hemp is making a major resurgence as an agricultural product, because the entire plant can be used to make a variety of different products:

  • The seeds are edible and high in caloric content.
  • The stalks and stems are very high in fiber content, and can be used to make textiles, cordage, and even construction materials.
  • The flowers and plant material can be chemically extracted for a variety of different chemical compounds that play a role in medicine, including CBD.
  • Cannabis roots are edible and used in old, traditional medicines.
  • Cannabis leaves can be used to make a juice that is supposed to help people with IBS and Crohn’s Disease.
  • The entire plant, when dried, can make excellent kindling and fire material.

In fact, Cannabis is so useful that the NCBI has a rather lengthy review of the plant’s different applications.


I hope that answers your question! Hemp is the same species as Cannabis, and the only real difference is in THC concentration. If you have any other questions, why don’t you let us know in the survey below, or join the community to discuss it on our forums?
