Do you have textbooks?

Oaksterdam has no required textbooks, and our programs contain all the information you will need.

The Cannabis Grower's Handbook by Ed Rosenthal is an excellent companion book and extremely useful reference, but it is not required to complete the Horticulture Program.

A word on the Author - Ed Rosenthal
Ed Rosenthal is the world's leading expert on the cultivation of marijuana.

Ed is also on the faculty of Oaksterdam University, the leading trade school for the cannabis industry. His classes teach pupils how different techniques can be used to improve their gardens' yield and efficiency.

Ed has always been driven by a desire to develop innovative, effective, and non-toxic methods of gardening. He was one of the original American writers to travel to Holland, bringing the knowledge and sophistication of European horticulture to the U.S. through his books and Ask Ed column. While his career has focused on cannabis cultivation, he is an avid gardener of edible plants and flowers. Ultimately, Ed believes that no matter the plant, a gardener should never be forced to resort to using potentially dangerous means to enjoy a bountiful harvest.
