Ed Rosenthal

Edward "Ed" Rosenthal, born on December 2, 1944, is an American horticulturist, author, publisher, and Cannabis grower. He has gained recognition for his strong advocacy for the legalization of marijuana use. Rosenthal's contributions to the cause were evident during the 1980s and 1990s when he served as a columnist for High Times Magazine.
In 2002, Rosenthal faced legal trouble when he was arrested by federal authorities for cultivation of cannabis. Although states have their regulations regarding the use of medical marijuana, the federal authorities did not recognize this authority. Consequently, Rosenthal was convicted in federal court, but this conviction was later overturned on appeal. He was subsequently convicted again but was not re-sentenced, as he had already completed his original sentence.
Rosenthal's activism extends beyond personal cultivation; he has been instrumental in promoting and developing civil regulation policies for medicinal marijuana. Following the passage of California's Proposition 215 in 1996, which authorized medicinal use of marijuana, Rosenthal collaborated with state and local governments to ensure the delivery of pharmaceutical-grade cannabis to patients who had a doctor's recommendation for marijuana use.
In addition to his work as an advocate and activist, Rosenthal has authored numerous books on the subject of marijuana cultivation. His writings have further cemented his position as a leading figure in the field.

    The king of growing! I have been “asking Ed” since the mid 80s. A valuable and thorough resource for the casual grower and expert farmer alike. Ed has decades of experience and this wonderful tool keeps getting updated as time goes on.
