Water is life. Not only is it essential for all living things, the polar molecule, H2O, is one of the most important variables in your garden. Yes, many folks overlook testing it or incorrectly assume their water is safe or good for their plants. Depending on your water source, it can even change throughout the year. Because of this it is important to test your water in both the wet and dry season for the first two years of any new cultivation project. Water tests can feel daunting at first. How do I take a sample? Is it going to be...

  One of the most important skills any grower can have is the ability to visually identify a deficiency or issue with their crop. Proper scouting and early identification of nutrient or IPM issues is critical to staying on target with your harvest goals. This can be confusing for newer growers and can take decades to learn, requiring constant repetition. This is especially true for cannabis growers with few scientifically backed representative images available due to prohibition. We are all familiar with the old nutrient deficiency posters that did little despite their best intentions to help growers determine nutrient issues. Where many vegetable...

clover, companion planting, cover crops -

I’d like to start by saying cover crops are amazing and have a ton of benefits. They are one of the best ways to improve soil health in agricultural soils. Cover crops can be used to increase organic matter, effectively raising cation exchange capacity in soils where it’s impractical to bring in compost or mulches. Certain cover crops like radishes help with compacted soil by breaking through tough layers of subsoil, making it easier for your main crop to increase it’s rooting depth. Having a cover crop protects the soil from erosion due to wind or heavy rains, and also...

To download the .pdf click here   Plant growth comparison of Cannabis sativa when grown in isolated containers versus communal bed systems.    Dr. Ben Higgins and Tad Hussey 16 June, 2019   Introduction The decision that all farms are faced with in choosing which containers (if any) to use for their crop(s) has both biological and financial implications. Not surprisingly, these implications are not mutually exclusive, as the type of containers used (e.g., hydroponics, potted soil, raised beds, ground-planted, etc.) inherently will express differences in ecosystem biodiversity. Furthermore, this decision as to which type of growing method used (e.g.,...

Download a pdf version Abstract: There currently exists many different methodologies for growing cannabis in controlled environments, however there is very little published research on the subject in regards to cannabis cultivation. Conventional approaches using bottled nutrients have a higher cost of production, which has become a challenge cultivators as the market price of cannabis has dropped dramatically. With an estimated revenue of 9 billion in legal cannabis sales in 2017 and estimated revenue of 11 billion for 2018, the emerging market is growing rapidly. Many of the current methods involving hydroponic cultivation have a large carbon footprint and negative...

Download a pdf version  Abstract: There currently exists many different methodologies for growing cannabis in controlled environments.  Many of the current methods involving hydroponic cultivation have a large carbon footprint and negative environmental impact due to the use of fossil fuels.  These methodologies only allow for the media to be used one or two times before being disposed of, which contributes to leaching of phosphates and other nutrients into our groundwater. An additional factor with cannabis cultivation is cost of production. The current market in WA and OR has driven the value of cannabis to record lows, resulting in many...

Most growers love the idea of re-using their soil, but it can be a bit daunting for a variety of reasons. In this blog post, I'm going to review what the advantages and disadvantages are, as well as lay out a simple plan you can follow. Advantages: The advantages of re-using your soil are numerous. You have a lower cost of production by not having to purchase new soil. It costs a fraction of what new potting soil costs to re-use soil. You also have a lower environmental impact, less labor, and better soil ecology over time leading to healthier...

There are many recipes out there for mixing your own potting soil. I've tried a bunch over the years, including most of the commercially produced soils on the market like Ocean Forest or Pro Mix. I'm convinced that with a little bit of work, you can produce your own soil using many local products and not only save money but make a much better soil for your plants.  Let me give a little history on our soils and how I started the process of learning about mixing soils. It started back in 2005 when I met a man in Portland...

I get this question a lot. Why would someone want to choose one growing container over another and how does it affect work flows and plant growth? Here's a quick comparison of the two options in an easy to read format. Containers: Pros:  Easy to move around Easy to transplant out of into another container Better for isolating or culling a plant Typically uses less soil per plant Easier to deal with pests and disease problems (soil can be removed) Easier to sanitize room for indoor environments Cons: Less space for root growth, which can be a limiting factor Potential...

There's a ton of reasons to consider Vegan amendments for your soil and fertilizer needs. For some, it's a life choice based on the food they put in their body, for others it may be a desire to not support the current meat industry and slaughterhouses. That's definitely something I can get behind. Now just to be clear, I don't personally believe Veganic or Vegan-grown vegetables/cannabis to be inherently better than other methods of gardening. At the end of the day, the plant doesn't know if the nitrogen came from a plant or animal source. In a forest environment, you...

The Top 5 Mistakes Growers Make You name it, and I’ve probably done it. I’ve killed a lot of plants in my lifetime, but each one has taught me a powerful lesson and improved my gardening. You can learn a lot from your mistakes, but below is a list of most common mistakes I see in being made by growers.  1. Letting the Soil Dry Out I've definitely heard this in the past. That it's best to let the plant experience wet/dry cycles and you want to let the pot dry out before you water again. With organic soils, it is...

Historically I have discouraged people from using specific microbial inoculants when growing, as many of these microorganisms can be found in greater concentrations and diversity in a properly made aerated compost tea (ACT). In fact, many of the "instant compost tea" or "microbes in a bottle" products I've looked at under the microscope over the past 10 years tend to be dead or completely dormant.  When I met Colin, the founder of Mammoth P, at Cannacon I was initially quite skeptical. However, he was able to answer all of my questions to my satisfaction and got me interested in the...

I'm hearing of more and more growers moving to "no-till" setups for their greenhouses, raised beds, and indoor gardens. The concept is simple, by not disturbing the soil, we are allowing for the microbes to establish soil structure and improve soil quality over time. There are many benefits to "no till," but I don't think we are truly comparing apples to apples when discussing our raised beds and indoor gardens. So for starters, let's differentiate between using an actual rototiller and just digging our indoor pots and beds. 2 totally different situations. Yes, tilling can be quite damaging to soil...

While Water Only Soils are convenient and can save time, many gardeners I find want to add more to their regimen and push plants to their limit in regards to growth and yield. Here's a few ways to maximize your plant's potential growth and yield. I've loosely organized these by the order in which I would prioritize them based on a cost/benefit analysis. Mycorrhizal Fungi - Mycorrhizal fungi is a "must have" for me and works well with our soil mixes. It's a one time application early in the plant's life, directly to the root zone. Mycorrhizal fungi will help with...

Container gardening, Fabric Pots -

As a long time organic grower, I've always been very careful about what products end up in my garden. If I'm growing an edible crop, I want to keep it as clean and free of chemicals and contaminants as possible. Until recently, the idea that my container could possibly be contaminating my plants by leaching dangerous metals or chemicals was not something I even considered as a possibility.  Personally, I've chosen to use fabric pots for most of my container growing needs. As you may already know, fabric pots offer a myriad of benefits to container growers. Fabric pots offer...

This can be a hotly debated topic among growers as to what's the best media for growing plants. In this article, I'll weigh in with my opinion on the subject as there are Pros and Cons to both. "Sphagnum" is a genus of approximately 120 different species of mosses known as "peat moss." Sphagnum and the peat formed from it do not decay readily because of the phenolic compounds embedded in the moss's cell walls. Peat moss can also acidify its surroundings by taking up cations, such as calcium, magnesium, and potassium, and releasing hydrogen ions. Under the right conditions, peat can accumulate to a depth of many yards. These bogs are slowly...

Fungus gnats (Ofelia and Bradysia species) are tiny flies similar to mosquitoes in appearance, though smaller at only 1/16th to 1/8th of an inch long. You may notice fungus gnats when you disturbing the soil or flying around near your lights. Females lay eggs in the soil and the larvae have a shiny black head and a whitish/translucent body.  While the adult fungus gnats don't damage plants or bite people, they can be annoying to find in your grow space and the larvae can be damaging the plant. Fungus gnat larvae consume organic matter, compost, fungi, and root hairs. *...
