CannNext Netherlands investigates cannabis strains in “weed experiment”

  • CannNext has successfully completed its 16th harvest in its Dutch growing facility.
  • Since the announcement of the Closed Coffeeshop Chain Experiment, CannNext has been conducting research into popular cannabis strains in NL and the US.
  • Offering 15 to 20 different types of cannabis operationally requires a lot of preparation and knowledge.
  • More research needed into the properties of seeds and cultivation recipes for different varieties.
  • Knowledge of plant composition and cultivation recipes is essential for setting up a cultivation facility and running multiple production schedules.

16th cultivation completed with research into seed varieties

CannNext successfully completed its 16th harvest in January 2021. In CannNext’s indoor research facility, studies are conducted every cultivation cycle to optimizing certain aspects of the cultivation, the growth process or the growth recipes. Since the announcement of the recreational tender “Experiment with a Closed Cannabis Chain”, CannNext has, in addition to its general research, focused on developing growth and cultivation recipes for popular cannabis varieties in coffee shops or points of sale in the Netherlands and the US . The research focused on successfully growing different cultivars in one growing room and growing plants from seeds.

Standardization of growth recipes for indoor recreational crops offers many opportunities

In the high production environment of CannNext, the varieties appear to grow very well with high yields, but with adjustments in cultivation recipes. The composition of the varieties also had a major impact on the layout of the cultivation facility – something that future growers should keep in mind in the experiment. Offering 15 to 20 different types of cannabis requires a significant amount of operational preparation and knowledge. Often there is only a limited amount of information available about these varieties grown under less optimal circumstances and this can be improved for the higher volume of indoor cultivation.

New varieties are monitored and adjusted daily for an improved recipe

Important aspects that growers have to consider when growing different varieties together are the specific characteristics and needs of each strain. First of all, a big difference can be seen between the height, the number of shoots and the need for irrigation. For example, CannNext has found that some varieties are one and a half to twice the length and width, but the yield is not much higher or nearly the same.

More varieties and different growth phases create a logistical challenge

It quickly becomes complex when multiple varieties are grown in the same grow room. “Sometimes we see that when planning a new large indoor cultivation facility, too little attention is often paid to the characteristics of a plant. For example, rough estimates are made of the yield and little account is taken of the characteristics and needs of the different varieties in the classification.” When market prices fall, very efficient cultivation is needed with little margin for error.

Organization of cultivation recipes and implementation is demanding

The organization of various short crops grown side by side requires a significant administrative organization, especially if you continuously work on improving your cultivation recipes with various measurements to assess the influence of changes in the recipe. Cultivation recipes vary enormously: not only for irrigation, but also in nutrition and light. It is a great challenge to meet all these individual needs and to optimize yields and save costs.

CannNext will continue research into the properties of medicinal and recreational varieties. In the first quarter of 2021, seven more new species have been selected that will also be tested in the research facility.
