Author and aficionado Greg Green blends a thorough understanding of marijuana botany with practical advice on coping with the day-to-day demands of maintaining a high-yield garden, and offers proven methods that maximize both yield and potency. Fully updated and illustrated in full color, and with techniques for both indoor and outdoor cultivation, this comprehensive guide covers everything growers need to know, including how to select the best plant genetics, soil and hydroponic grows, dealing with pests and predators, advanced systems and breeding, and protecting the crop from nosy neighbors.
