Workshop – Basics of The Cannabis Industry and Cultivation

For investors and growers we developed a workshop program to gain insights in the basics of cannabis cultivation and what are the opportunities and challenges for the medicinal cannabis industry. Not only for cultivators/investors but also seperate modules for suppliers. So, what does it mean for a supplier/greenhouse builder to be active in medicinal cannabis industry.

Detailed example of one of our most popular workshops:


Understanding the business and politics of cannabis

Goal: understanding the world of cannabis in order to address the implications for the cannabis project to increase the success rate.


Cannabis cultivation basics; systems & planning

Goal: understanding the possibilities and requirements for cannabis cultivation to determine the required cultivation set-up.


Cannabis cultivation crop phases

Goal: understanding the crop phases; mother plants, propagation, veg and flower phase and post-harvest


Daily cannabis cultivation (climate, IPM, root zone management)

Goal: understanding the daily operation requirements of cannabis cultivation

Sarka Betke – managing director High Five Group (Czech)

“As a newly established company in such a dynamic industry as medicinal cannabis is, we have a lot of decisions to make with regards to the different cultivation approaches. We also needed to fill in some gaps in our knowledge (not coming from the pharmaceutical industry ourselves) of the implications of farming such a highly regulated plant at a large commercial scale. The workshop with Cultivators led by Sonny exceeded our expectations. It covered all important parts, discovered some blind spots we had in our business plan, and helped us to shape our business model better.

I can highly recommend this workshop to any cultivator who is entering this space. The full day workshop is worth weeks of research on your own, topped with a lot of practical examples of good and bad practices from the industry.”

Evagelos Drimtzias & Christos D. Katsanos – IQ CROPS Ltd (member of The DKG Group)

“We have to say that the basics of cannabis cultivation course was one of the most effective courses we’ve taken in our professional careers. The seminar provided a great overview of what Medicinal Cannabis actually encompasses and Sonny as the instructor demonstrated in-depth knowledge of the subject. After this seminar we decided to collaborate with Cannabis Cultivators in the consulting area in our cannabis projects.”

Cultivation design improvements in hydro lettuce

With 8 ha greenhouses on 2 locations. Owners Johan Desmet and Mirjam Vandoorne are the biggest hydroponic lettuce growers in Belgium. They grow different lettuce types on a mobile gully system (NFT) and have regularly invested in the most modern growing techniques like LED light and shading screens. Cultivators advices this company for 4 years on cultivation and technical improvements.

Recently this grower, with advice from cultivators, also invested in in-house young plant propagation. Before, the plants where bought at an external young plant producer. But the quality of young plants was regularly fluctuating, causing growing issues later on in the hydroponic greenhouse.

This investment was done with thorough research of the ideal growing medium and technology. And the decision was made to invest in a fully automatic seeding line and germination room. Part of the existing growing gutter installation was modified with different propagation gutters. Also the young plant growing greenhouse was equipped with a hybrid artificial light system to be able to steer optimally on the young plants. The resulting young plants are much stronger and have a more stable quality.

Training Legal Compliance Medicinal Cannabis

All companies in the industry face the same challenges around compliance. We help suppliers with compliance & quality as this is a necessity to ensure safe and sound medicinal cannabis. Managing compliance & quality is a complex, time consuming and costly procedure. Cooperation and specialization improves quality and reduces costs per company. Setting-up compliance protocols with Good employment practices and social responsibilities. And monitoring regulatory updates and license validity.

“Especially in the cannabis industry compliance should not be underestimated, due to the complex and rapidly changing regulatory landscape. The knowledge provided during the training of Cultivators gave us practical insight to develop a clear policy for the cannabis industry.”

NZ cannabis workshop: Content was worth its weight in GOLD

During four morning sessions in August, Sonny Moerenhout, Director and Agronomist of Cultivators provided New Zealand participants a riveting growing workshop focused on medical cannabis cultivation.  I would like to thank Cultivators for teaming up with Grower2Grower to allow us to organise and host the Medical Cannabis (MC) growing workshops.  As a greenhouse vegetable advisor, I found these sessions fascinating.  The technical nature of the workshop and plant agronomy information was second to none, and all four sessions were equally captivating.

It is now abundantly clear, from my interpretation, that without greenhouse hydroponic knowledge and obtaining the agronomy skills required for growing MC, in either greenhouse or factory operations, may place companies at a disadvantage.  MC growers that have been fortunate to be involved with high-tech greenhouse vegetable or flower growing will have a distinct advantage when it comes to final production outcomes.  I believe that growers who have not had a practical greenhouse background will find it a very steep learning curve.

There are now more than a handful of companies moving from the research phase to the production phase in New Zealand, currently setting up their growing facilities.  It was pointed out during the first workshop that there is no F1 hybrid cannabis seed currently in the world.  What does this mean? Basically, no two plants germinated from seed will be identical. They can vary phenotypically and in chemical fingerprint. This is an issue.  Every company will have to develop a ‘Mother’ stock.  Cuttings from the mother stock will then be required for propagating and growing to flower/harvest stage. What this also indicates is that it will be very hard for two different companies to provide dry flower product with the exact same composition of cannabinoids unless both companies agree to produce from the same mother stock.

Response from the Workshop

Feedback from the growers, suppliers, educators and researchers that were part of the workshop was overwhelmingly positive. The content and delivery of the presentations was well received.  Cultivators, for sure will be an extremely successful medical cannabis consulting service concentrating on what is possibly the most important piece of the MC process, and that is the actual growing.

Session descriptions

Session one was an introduction to cannabis.  This section covered cannabis sp. ingredients, market overview, cultivation requirements, compliance, quality standards.  Included were basic Anatomy & crop physiology.

Session two covered cannabis systems and planning.  This section covered design of the cultivation facilities (factory or greenhouse), energy consumption, plant density systems, crop planning, substrates, crop planning and facility design.

Session three covered cannabis crop phases.  Included in this tutorial was the four crop phases, genetics, plant architecture, vegetative vs generative plant steering, flower development, when to harvest and yield examples.

Session four covered climate control:  Uniform crop development, assimilate balance, light, temperature, humidity, irrigation and CO2 requirements. Crop measurements, supplementary lighting, greenhouse climate screens, nutrient balance, integrated pest management and diseases including fungal and crop physiological disorders.
