Indoor, Outdoor, or Greenhouse, and why?
It really depends on where you’re growing and what products you’re aiming to produce:
- Where cultivation needs to take place.
- If you’re in an area with limited land, indoor may be necessary.
- The kind of products you are producing.
- If you’re making oil, outdoors and cheap makes sense.
- If you’re growing for flower, then you’ll probably want indoors or a greenhouse.
- The environment you’re growing in.
- Ideal growing climates mean that greenhouses are your best option.
- Challenging environments make an indoor grow may be the better option.
If you had a lot to spend on a grow, what would you buy, and why?
I would say that investment in automation is key, because the biggest expense in cultivation is labor. People should be used for work that is very sensitive or requires high-level judgment and decision-making.
Do you have any favorite strains you like to grow?
I stick with what are called the “old-school” strains. These are strains that have special attributes which both consumers and growers find attractive. These strains are easy to sell.
Tell me about your environmental controls and automation.
Northern Oregon’s rainy season is long; heating and supplemental lighting are crucial. DryGair systems have been awesome because we don’t have to invest in 3 separate systems. Instead, we can invest in one system and make it a focal point in our production.
What is your preferred methodology for handling pests?
Russet mites and broad mites in Oregon have proven to be very challenging. They are difficult to spot when their numbers are small. You can treat the infestations with pesticides, but you sacrifice quality and money by doing so. I maintain a preventative protocol using:
- Various essential oils
- Neem oil
These natural, organic pesticides are quite helpful for prevention without sacrificing quality.
What’s your preferred approach to preventing fungal pathogenesis?
While fungicides work to a limited extent, you greatly sacrifice quality. As a result, fungicide use is unsustainable, because you will not be able to sell your product.
Therefore, the best strategy is prevention via environmental control. You need to keep the crop dry. Your structure should divert condensation away from the plants, and your environmental controls should avoid the dewpoint. I personally recommend DryGair’s products as very effective solutions for the price.
What are some of the biggest challenges you’ve faced?
One of the biggest challenges I faced was in my first year of growing back in Israel. I was growing AK-47s and Purple Kushes and thought I was hot stuff. Two weeks later, 90% of the plants had to go to the garbage because botrytis had taken over. My humidity was not under control.
Most recently, Marion County of Oregon opted out of recreational cannabis in the last round of elections. That meant we couldn’t expand our operation how we originally planned.
What are some of your biggest triumphs?
My biggest triumphs relate to people. At the end of the day, it’s all about the people. You could have the best technology in the world, but if you don’t have a good team to support that, then you don’t have much.
What differences have you seen between Israel and Oregon cannabis cultivation?
Regulations were virtually nonexistent in Israel while I was there. Israeli authorities allowed producers to produce as much medical cannabis as they could with basically no guidelines. They eventually regulated the price of the medicine for the patient. The result of this legislation meant that small, niche growing wasn’t possible. Growers needed to produce in bulk.
In contrast, Oregon’s recreational program was really thought through beforehand. There were some glitches and difficulties at first, but the smart people in the OLCC did a great job putting together a modular program that could be upgraded relatively quickly. On the other hand, the scale of production is extremely limited. Operations are limited to a small family farm. The market is limited to expansion.
What advice would you have for a new grower?
Talk less, listen more. It’s not about your ego, it’s about the plants. It’s not about your ideal garden, it’s about building good systems. Surround yourself with a good team of professionals that you can trust and learn from. Remember, the cannabis market didn’t invent agriculture. A good farmer can be easily trained to grow cannabis.

Here are a few factors that affect the decision:
- Where cultivation needs to take place.
- Cannabis is mostly a local market, since there is no export in the US. If you’re based in an area with limited amount of land (IE Los Angeles), indoor may be a necessary option for you.
- The kind of products you are producing.
- If you’re growing to make oil, it doesn’t make sense to grow indoors or in a greenhouse. Quality standards for oils aren’t strict. You can grow outdoors as long as there’s a suitable environment.
- If you’re growing for flower, then you’ll probably want indoors or a greenhouse because you get much more control.
- The environment you’re growing in.
- If you have an ideal growing climate, then greenhouses are usually your best option. You get the control of an indoor grow, with the reduced costs associated with an outdoor grow thanks to the sun.
- If you have a challenging environment, due to heat, cold, short seasons, etc. an indoor grow may be the better option.

It also depends on the quality of cannabis you’re looking to produce. If you want to make top-shelf flower for smoking, a greenhouse is preferable. If you’re planning on growing cannabis that is geared for extraction, then a predominantly outdoor grow would make sense. I would only limit my size based on the regulations of the county and state.
Now that said, technology is supposed to solve problems in a cost-effective way, but sometimes it doesn’t take an advanced solution to solve a complex problem. Don’t waste money on expensive solutions to problems when you could invest a few hundred dollars in a simpler, low-tech solution.
As a grower though, you should always have a good selection of two or three strains per “strain category.” Strain categories include:
- Smell and taste
- Cannabinoid levels
You shouldn’t have too many different strains, as you can spread yourself too thin and your grow will become too difficult to manage.
While I was growing in Israel, I started to become familiar with DryGair systems. I found them attractive because they developed their systems with three components of climate control:
- High airflow capacity
- Heating solutions, depending on the model
Unlike Israel, northern Oregon’s rainy season is long; heating and supplemental lighting are crucial. DryGair has been awesome because we don’t have to invest in 3 separate systems. Instead, we can invest in one system and make it a focal point in our production. It’s extremely affordable and efficient.
DryGair has large units available that work on 3-phase electrical service that act upon approximately 10,000 square feet. They are modifiable for additional heating and cooling units. I also recommended to DryGair that they develop a small unit that could work on one-phase electrical service (120V), since the majority of their units require 3-phase electrical service. Many remote growers in the US do not have 3-phase service, and single-phase units will be a major boon to the industry.
The dehumidifiers also interface with our master controllers. Each system can work in one of two modes: the system can regulate itself based on preset thresholds or it can be controlled by a master controller. Each unit has its own standalone controller and sensors. In our case, we connected the dehumidification systems to our main climate control systems.
But when I moved to Oregon, russet mites and broad mites have proven to be very challenging. They are very difficult to spot when their numbers are small. If you’ve spotted their effects on the plant, it’s already a really bad infestation. You can treat the infestations with pesticides, but you sacrifice quality and money by doing so.
Thus I prefer to maintain a preventative protocol using a variety of products as a weekly spray. My go-to active ingredients include, but are not limited to:
- Various essential oils
- Neem oil
These natural, organic pesticides are quite helpful for prevention without sacrificing quality. However, it’s not just what you use, but how you use it. You need to properly apply your prevention protocols in order to achieve uniform coverage. Don’t waste your time or money on improper application and dosage.
The applicators you choose to use depend on the grow environment. Generally speaking, in an indoor environment you’ll probably use atomizers or backpack sprayers, as both of which are very efficient and small. In a greenhouse, you can apply efficiently prevention measures through the water lines or backpack sprayers. If you’re outdoors, you can use commercial farm equipment to spray properly. If you want to use an automatic robot to spray, you need to have your grow space designed in advance with tracks and other requirements.
The bottom line is that cannabis is a challenging crop for fungal management because it’s a flowering crop that needs to be kept in the flowering state for a long period of time. No other crop has that concern. Flowers are very sensitive plant tissue, and keeping the plant in a continually flowering state leaves it very vulnerable to pests and fungus.
Therefore, the best strategy is prevention via environmental control. This means you need to keep the crop dry. You don’t want free water anywhere on the crop. This means that both your structure will need to be designed to divert condensation away from the plants, and your environmental controls will need to prevent your plants from reaching the dewpoint and forming dew on the leaves.
Generally, the way to avoid the wet surfaces issue is through dehumidification. I personally recommend DryGair’s products as very effective solutions for the price. I discovered DryGair about 4-5 years ago when I was struggling with Botrytis in Israel, and they have helped me move away from fungicides towards environmental control.
You could have the best technology in the world, but if you don’t have a good team to support that, then you don’t have much.Elad Spiegel
Two to three weeks later, 90% of the plants had to go straight to the garbage. Botrytis had taken over most of my crop, because my humidity was not under control. It was definitely a learning experience, I’ll say that. If you let things devastate you, you’re probably not in the right business.
My most recent challenge came during the last round of elections in the US. Most of my friends were disappointed by the presidential election results, but in my case I was worried by local election results. Marion County of Oregon opted out of recreational cannabis, which meant we couldn’t expand our operation in the way we were originally planning. We had to move out of the farm we were planning to use and sell it. The truth of this industry is that regulatory challenges underpin everything we do. Rules and regulations can determine how we operate and design our systems. We live and die by compliance.
You could have the best technology in the world, but if you don’t have a good team to support that, then you don’t have much.My biggest triumphs relate to people. We can talk about greenhouse technology all day long, but the reality is that plants don’t just grow just because there’s technology. Plants grow because there are people there to manage them. At the end of the day, it’s all about the people. You could have the best technology in the world, but if you don’t have a good team to support that, then you don’t have much.
And, in truth, one of my biggest triumphs is that every day and every year, we cultivate a team of people that are able to work together cohesively with the common goal of producing the best medicine for patients.
If you can step back from your operations and not worry, you’ve built a good team. In Israel, I was called into emergency military service and had to leave for 3-4 weeks. When I came back, everything was fine. If you can take a week off and everything is perfect when you come back, you have a good team.
Recently, the Israeli government has started to become more involved in cannabis regulations. They implemented strict quality standards and GAPs. That’s a major positive. Additionally, today you can find another 35-ish cultivation licenses that were issued back in March this year (2017). Production capacity is going to increase dramatically and most of it is intended for export. If you want to hop into the global cannabis market, Israel is the hottest place to be.
In contrast, Oregon’s recreational program was really thought through beforehand. There were some glitches and difficulties at first, but the smart people in the OLCC did a great job putting together a modular program that could be upgraded relatively quickly. There’s still room to improve, but the starting point was excellent.
On the other hand, if you look at the cannabis market in Oregon, the scale of production is extremely limited. Operations are limited to 10,000 sq ft for indoor cultivation, and 1 acre for outdoor cultivation, which would be considered by most farmers to be a family farm. The small scale of operations keeps cannabis prices high by inhibiting better profit margins. In turn, this makes the black market appealing to failing growers. Additionally, the market is localized solely to Oregon, limiting growth potential. Cannabis cultivators have a ceiling in their way that limits the size and scale of operations. All that said, Oregon voters wanted this. They didn’t want corporate cannabis. The market is limited to expansion, unlike in Israel.

I learned from the start that I wasn’t born a professional agronomist. I was lucky enough to be surrounded by professionals as I learned and I was smart enough to ask the right questions. When I received advice from them, I implemented their suggestions and solutions in a timely fashion. Surround yourself with a good team of professionals that you can trust and learn from.
Remember, the cannabis market didn’t invent agriculture. There’s a lot of very smart people with years of experience that would be happy to share their knowledge. A good farmer can be easily trained to grow cannabis.
About Golden Leaf and Elad
I found a good opportunity as Head Agronomist for Cann Pharmaceuticals, also known as, “Better” and I took full advantage of the position. Israel’s medical program started off with virtually no restrictions. SOPs, GAPs, etc. had not been established yet. You could grow as large as you wanted. I helped take Cann from a struggling new company to the second largest production operation in Israel.
In 2015 I got recruited for Golden Leaf Holdings, based out of Oregon. I relocated from Israel to become the Director of Cultivation here.
On a commercial level, American consumers have a connoisseur’s taste for flower. As long as consumers prefer connoisseur-level flower, that is what cannabis growers will need to supply. So far we have seen leaps and bounds in grow quality, and I expect that trend to continue. I also expect to see better-educated growers in the future. Most growers are still coming out of the black-market from small-scale grows, and it’s hard to translate black-market skills into large scale, commercial skills. The market will need to resolve the demand for skilled and educated labor.
Also, it almost goes without saying, but technology is always improving. I expect more automation solutions in the future. As growers get a handle on running large facilities, the next generation of facilities will be more cost-effective and competitive.
