Our Cannabis Garden
Our pride and joy is our beautiful, organic, fully-flowering public Cannabis garden, situated in the basement of the Cannabis College.
No trip to Amsterdam is complete without a visit to our garden. These gorgeous plants form one of the world’s only publicly accessible flowering Cannabis gardens, so please stop by for a truly unique experience.
We always have a selection of the finest quality Cannabis strains growing, and we only use organic, high quality and thoroughly tested nutrients. This presents visitors with an excellent opportunity to gain knowledge directly about the plant by observing it in a living, growing state, and asking our staff questions about strains, lights, techniques such as super cropping and LST, or how to treat and prevent particular pests and diseases.
Visitors are not only allowed but encouraged to take photographs
History of our Cannabis Garden
Since 1998 we have provided accurate, objective information about all aspects of Cannabis and hemp and have cultivated a beautiful organic flowering garden in our basement. Much like the Cannabis College itself, the garden has gone through several changes over the years, from the amount of plants and the layout to our choice of cannabis nutrients and grow techniques.
In the early days the Cannabis College garden hosted around one hundred little plants, but was reduced in size shortly thereafter to a display of five huge plants (roughly three months in vegetation each). The indoor Cannabis College garden reflects, and is contingent upon, the tolerated allowance of outdoor plants in The Netherlands, currently set at a maximum of five plants.
Some of you might remember the typical Amsterdam basement (long and low-ceilinged) had been cleared out in order to provide more space for our plants and visitors. With huge stone basins spread out through the basement that would hold our beautiful plants.
The reason we had to restrict the public’s access to the plants is unfortunately our history of contamination from prying hands. Presenting a controlled setting also allows us to compare strains in different growing environments and thereby provide more extensive information.
We decided to construct small ‘grow rooms’ in order to demonstrate cultivation methods that are rapidly gaining popularity. This also allowed us to show our visitors the actual different stages of cultivation.
Because the cannabis industry has taken such a leap forward and almost daily new products/ideas are introduced to an already fast growing market. In 2018 we decided we also had to update and grow along. Resulting in a fresh new paint job for the upstairs and upgrading/ reconfiguring our grow rooms in a way that minimises external (temperature) influences and diseases.
Regarding technology, the plants are still (and always will be) cultivated in an organic fashion, meaning that they are grown in soil with organic nutrients and natural pesticides. The plant begins under a 250W CFL (Compact fluorescent Light) in our vegetation room, a new addition to the layout, often with a variety of techniques used to control the shape and size of each plant. One example enjoys a classic 600W HPS (High Pressure Sodium) light. Lastly we currently use/display a set of 200W LED bars from TodoGrow in flowering stage.
Much of what is on display in our garden has been grown using donations from wholesalers, retailers and organic nutrient companies. More information on each of these generous organisations is available in the links section of this site.
