Mr. Rosenthal began his 'Ask Ed' column in High Times magazine in 1983. The success of the column over the decades has culminated in this treasury of information. Topics discussed include lighting, indoors, outdoors, flowering, harvest, troubleshooting, breeding, use & much more. It also has a detailed pests & disease section with colour pictures. Despite the volume of detail, it's really easy to use and is written by a long-standing expert in the field. If it ain't in this book, it ain't worth knowing...! Organised by topic for easy referance. Helpful navigation tools guide you directly to the info you're after. Beginner to advanced cultivation topics. The answers you need for a healthy and productive garden. Author: Ed Rosenthal 410 pages, Softback
