Ed Rosenthal is the world's leading expert on the cultivation of marijuana. His books have sold well over two million copies and his most recent edition of "Marijuana Grower's Handbook" has revolutionized the field. 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 the yield and efficiency of their gardens. Beyond the garden, Ed views marijuana law as a crucial social issue and has been active in promoting and developing policies of civil regulation. In 2003 he was tried in Federal Court for cultivation in a trial where the jury was not allowed to hear that he was deputized by the City of Oakland to provide marijuana for patients. His trial shifted public opinion in favor of state medical marijuana laws.
Today he continues to head Quick Trading Company, the marijuana-specific book publisher he founded nearly 40 years ago in addition to being a freelance contributor for a variety of popular publications, including Cannabis Now Magazine.
His best-selling titles include; The Big Book of Buds series, Marijuana Garden Saver, Best of Ask Ed, and Marijuana Grower's Handbook, among others.
