Growing Quality Medical Cannabis


 by Jeff Desjardins from Visual Capitalist.

By 2027, it’s projected that the legal cannabis market in the U.S. and Canada could hit $47.3 billion in size. That will make it bigger than annual global sales for raw metals like nickel and silver put together. It would be a size that even exceeds the North American pork market.

But while almost everyone has a sense of the basic mechanics of mining or ranching, knowledge around the essentials of cannabis are understandable not as well in grained in our culture.



Today’s infographic comes to us from The Green Organic Dutchman, and it breaks down the anatomy of a cannabis plant, the differences between types of plants, and also the basics around cannabis cultivation.

Here are some of the most important things you need to know about the Cannabis plant: 

1. Plant Anatomy: 

Commercial cannabis comes from the female species, which have long skinny stems and large, iconic fan leaves. The plant is trimmed down into buds, which come together in a cola at the top of the stem. Trichomes are a blanket of crystal resin coating the cannabis plant, and they contain both terpenes and cannabinoids.

2. Cannabinoids
The two most well-known cannabinoids are THC and CBD, which also occur in the largest volume.

    1. Delta-9-tetrahydrocannabinol (THC) is known to cause psychoactive effects or the “high” felt from cannabis.
      1. Effects: pain relief, anti-nausea, sleep aid, appetite and mood stimulant.
    2. Cannabidiol (CBD) lacks nearly any psychoactive effect, making it preferred as a medicine.
      1. Effects: pain relief, anti-nausea, anti-inflammatory, anti-anxiety, seizure reduction.

Other cannabinoids such as cannabichromene (CBC), cannbigerol (CBG), and cannabinol (CBN), have similar therapeutic properties. Research is also validating the plant’s efficacy in treating medical conditions such as cancer, multiple sclerosis, PTSD, and Alzheimer’s.

3. Terpenes
Terpenes are organic, aromatic compounds found in the oils of all flowers, including cannabis. Interestingly, these oils have their own independent medical potential that is waiting to be unlocked. Cannabinoids and terpenes work in harmony, resulting in an “entourage effect” and enhances the medical properties of cannabis.

4. Sativa, Indica, Hybrid 
There are two common types of cannabis plants: sativa and indica.

Sativa plants have long and thin leaves that are lighter in color. Buds are long and wispy, and feature red or orange coloring. They tend to contain high THC and low CBD levels – optimal for daytime use, described as being energizing, stimulating, and creative.

Indica plants have leaves that are wide, broad, and deep in color. Buds are dense and tightly packed, featuring purple coloring. Indica usually contains medium levels of THC, and a higher amount of CBD. Its effects are often described as being relaxing and calming, which is more optimal for nighttime use.

It’s also worth noting that hybrid strains can often bring together the best qualities of both into one plant.



Every stage of growth of a cannabis plant needs different care that includes controlled lighting, humidity and temperature. The Munters ML Plus System is and ideal Climate Control System that provides heating, cooling, humidity and dehumidification, an all-in-one energy efficient Climate Control System in one unit.

Our award winning climate control solutions are designed to maximise efficiency and performance, and offer a superior solution for any requirement, whilst being better for the environment.

Optimal conditions for Cannabis growth

1. Germination (Seed): 1-2 weeks
Seeds ready for germination are dark brown, hard, and dry. Encourage sprouting by watering seeds in a paper towel.

2. Seedling: 2-3 weeks
Move seeds into growing medium. Plants need the maximum light at this stage, and appropriate water levels. Cotyledon (seed leaves) and iconic fan leaves will grow.

3. Vegetative: 2-8 weeks
Plants need flowing dry air, fresh warm water, and increased nutrients – especially nitrogen. It’s important at this stage to separate male and female plants before pollination to prevent female plants producing seeds instead of trichomes.

4. Flowering: 6-8 weeks
Gradually reduce light exposure to produce medicinal qualities. Increase phosphorous levels and decrease nitrogen. Fertilizers can help stimulate bud formation.

5. Harvesting
Trim and dry the buds. The plant is ripe when buds turn from milky white to reddish orange. Harvest once 70-90% of pistils are browned for maximized taste and effect.

Cannabis is a very sensitive plant to grow and is particularly sensitive to high humidity. At certain stages of the cannabis plant life, different levels of humidity are needed so that seeding, growing and flowering takes place optimally. 

Cannabis grows well in South Africa’s climate and now that the regulator has awarded cultivation licenses, large-scale local production is a step closer. Medicinal cannabis has become a growth industry in the South African healthcare sector, with a wide range of clinical applications.
