As a founding member of High Times Magazine and a former columnist known as the "Guru of Ganja," Rosenthal has played a significant role in documenting and advancing cannabis cultivation knowledge. His work spans decades of research into optimal growing conditions, plant genetics, and horticultural techniques. In addition to his writing career, Rosenthal has been involved in cannabis policy reform and has served as an expert witness in federal and state courts.

His publishing company, Quick Trading, has produced numerous books on cannabis cultivation and policy, establishing Rosenthal as one of the leading authorities in the field. He continues to write and update his works to reflect modern growing techniques and changing legal landscapes.
