Cannabis seeds, or "genetics," are the first thing you need if you want to grow cannabis. You can purchase cannabis seeds through our trusted vendors, a vendor of your choice, or you can even get seeds from other growers. Just be sure to check out legal restrictions in your area.
Feminized Seeds - Plants that have been treated, usually with colloidal silver, to ensure the seeds they produce are female.
Regular Seeds - Cannabis seeds that flower in response to a change in photoperiod. When purchased, expect a mix of male and females due to the 1:1 sex ratio of regular cannabis seeds.
Autoflower Seeds - Cannabis seeds that flower in response to their age, not to a change in photoperiod
Germination refers to that early time post plant when your cannabis seeds pop their tap roots. Seeds CAN be germinated in their pot but many growers like to supervise the germination process to assure maximum germination rate.
Alternatives to germinating in a pot include Paper Towel germination, germiniating in a cup of water, or even starting with specialized pods in a small greenhouse dome.
Soil is a popular choice for growing cannabis. There are a variety of soils on the market to choose from but you don't want to go cheap just to save a little money. Discount soils can often contain cannabis pests or diseases.
In addition to traditional soils some growers grow in a soil substitute such as coco coir or with soil additives such as vermiculite.
Plants need water and cannabis is especially thirsty. Make sure you go easy on the water in the seedling stage as it's easy to drown these girls if they get overwatered.
There are a variety of watering strategies including hand-watering and automated watering. An automated system can take the guess work out of your grow, though continued monitoring is important to make sure your plants don't get too dry.
You'll also want to make sure your water is pure. Most growers choose to go with filtered water or even reverse osmosis water. The important thing is that your water is clean and free of additives and chemicals that could hurt your cannabis plants. Be sure to check the pH level of your water too, before and after adding your nutrients.
While many soils come with nutrients already in the soil, it's better to start with an inert media and add your own nutrients. These macro and micro nutrients are available from a variety of retailers in their ready to use form. Many growers like to purchase the constituent parts and build their own nutrient regimen.
Cannabis Macro Nutrients - Nitrogen, Potassium, Calcium, Magnesium, Phosphorus, and Sulfur
Cannabis Micro Nutrients - Chlorine, Iron, Boron, Manganese, Zinc, Copper, Molybdenum, and Nickel
There are a wide variety of grow lights you can use for cannabis. If you're growing outdoors, no additional light is needed, the sun gives you all you need assuming you're not at an extreme latitude.
If you are growing indoors you have the choice of the type of light you'd like wether it's CMH, HPS, or even LED. Most growers swear by their light of choice and a few years ago, very few would even THINK about using LEDs, however, advances in LED technology have made them a valuable piece of equipment among hobby growers and professionals alike. An additional pro for LEDs is that they use much less energy than traditional cannabis lighting in addition to giving off little heat. That means you'll be able to save money on your grows climate controls.
Where are you going to grow? Do you have an outdoor garden? A single room? A closet? Maybe you're considering a grow tent. Either way you need to match your space to to the needs of the plant. A smaller grow space will require smaller plants. Fortunately there are a variety of seed strains perfect for small space growing. How much space will you need? Find out with this grow tent configurator.

What are feminized seeds?
Feminized seeds are obtained from plants that have been treated with colloidal silver or silver thiosulfate. This process forces the germinating seed to develop as a female, which is good for growers.
Are there advantages to feminized seeds?
Absolutely! Feminized seeds take the guess work out of the number of seeds you need to germinate, and you won't have to worry about males pollinating your ladies, which will significantly decrease the quality and yield of your harvest.
What are autoflowering seeds?
Unlike regular seeds, autoflower seeds have been crossed with the ruderalis cannabis species which forces them to flower when they're old enough, not in response to the light duration. This will take the guess work out of when to switch from veg growth to flowering in your grow.
Is it safe to order seeds through the mail?
People always wonder about the legal risk of purchasing cannabis seeds through the mail. Legitimate seed vendors (including those we recommend) ship discreetly to most locations. Seeds can be stopped by customs, but this doesn’t happen often. You also want to make sure that wherever you decide to purchase your seeds will also ship to your country. This information should be transparent and available on the vendor’s website.
Where can I buy seeds safely?
There are a number of good seed vendors out there. Our recommendations are established companies with great customer reviews so you know you’re purchasing quality seeds.
Beware of Seed Scams
If you’re contacted via social media to purchase seeds, chances are you’ve been targeted for a scam. We recommend using established cannabis seed vendors such as those we recommend above.
Questions you should ask before purchasing cannabis seeds online
Do you recognize the name of the company name?
Branding goes a long way and a recognized, established brand is something to consider when purchasing seeds online.
What are customers saying in their reviews? Did they receive their seeds? Were they high quality?
Researching these questions will increase your chances of being happy with your seed purchase.
Do you know anybody who has used them as their supplier?
Word of mouth recommendations are very powerful in the cannabis community. Someone else's first hand experience can be helpful if you aren't sure about which brand of seeds to purchase.
What’s their return or refund policy?
A good seed shop should at least have generally positive reviews and a well-defined refund or exchange policy.
Assessing Seed Health
A good seed vendor should only ship out quality seeds. Here is what to look for when you receive your seeds to assess their overall health.
- Dark color with stripes or spots (white or green seeds are too immature to sprout).
- Waxy, shiny coating: While not critical, this is a sign that the seed is healthy.
- Hard shell: You should be able to apply light finger pressure without the seed cracking. If the seed buckles under light pressure, the seed is either infertile or dead.
- No cracks: Healthy seeds will have their seed coat intact without damage. Check for holes too, as insect pests may dig into seeds for the delicious starch.
