With 512 full-color pages and 1120 full-color photographs and illustrations, Marijuana Horticulture: The Indoor/Outdoor Medical Grower’s Bible is the most complete cultivation book available today. The Fifth Edition of the former Indoor Marijuana Horticulture: The Indoor Bible was originally published in 1983, when it immediately became a best-seller. New greenhouse and outdoor growing chapters make this new edition a book indoor and outdoor growers will keep under thumb. These two new chapters complement the existing fifteen chapters, which have been rewritten, significantly expanded, and updated with the most current information. Dr. John McPartland contributed a new medical section, and ten cannabis web sites were profiled. All chapters pertaining to plant growth—seeds, seedlings, clones, vegetative growth, flowering, and harvesting—doubled or tripled in length and detail. Hydroponic and organic growing sections are new and greatly expanded. The twenty-nine page “Hash and Oil Making” chapter explains dry-sieve and water hash production in simple, pictorial detail. The thirty-page “Breeding” chapter, written by expert breeder Chimera from Chimera Seeds, is straightforward and easy for all growers to understand and apply. The book’s credits list more than three hundred contributors and reads like a who’s who in the world of cannabis cultivation. Any grower, casual or serious, will find hours of instruction and indispensable, tried and true help within the Bible’s pages.
