Ladybirds are great for natural pest control

Since 1998 we have provided truthful, objective information about all aspects of Cannabis and hemp and have cultivated a beautiful organic flowering garden in our basement. Recently the College experienced a bit of an upgrade.

In the early days the Cannabis College garden hosted around 100 little trees, and then reduced in size shortly thereafter to a display of five huge plants (roughly three months in vegetation each). The indoor College garden reflects and is contingent upon the tolerated outdoor plant total in the Netherlands, currently set at a maximum of five.

Our five big plants remain in the brand new garden but now in a different format. The typical Amsterdam basement has been cleared out in order to provide more space for visitors and information, and two of the plants are no longer in the front of the garden. Rather, the volunteers at the College decided to construct a custom grow box in order to demonstrate a cultivation method that is rapidly gaining popularity. We have also chosen to restrict the public’s access to two of the plants due to our history of contamination from prying hands. Presenting a controlled setting also allows us to compare strains in different growing environments.

The remaining three plants are unrestricted in the original viewing area, as our crew refuses to wall in the garden. As is our tradition visitors may still approach the plants and experience the different fragrance of each variety as well as closely observing the crystals (trichomes). Of course, no touching or sampling is allowed, but photos are highly encouraged!

Regarding technology, the plants are still (and always will be) cultivated in a bio-organic fashion, meaning that they are grown in soil with organic nutrients and natural pesticides (when necessary). The new tiled grow box has a maximum capacity of 1600 watts of air-cooled high pressure sodium light (HPS), and the remaining three plants are enjoying 600 or more watts of HPS each, all under brand new Lumatek digital ballasts. Our analogue days are behind us, and for tourists this means that photos will turn out better!

Much of what is on display in our garden has been donated by wholesalers, retailers and organic nutrient companies. More information on each of these organisations is available throughout the site.
