Comment: Appears to cover most aspects of marijuana cultivation, indoor and outdoor, in question and answer format, rather than step-by-step guide. The answers are well-researched and stated in understandable terms. There are numerous photographs of cannabis and cannabis plants, but only 1 diagram (of pest damage). I would consider that this book would appeal to the experienced grower who is seeking answers to the more technical or obscure questions.

One question of particular relevance (Systems: p99): The questioner (from Tucson Arizona) asks about constructing a 3-chamber grow-room in a 7Ã x 12Ã space, with separate areas for clones (with fluorescents), central growth (1000W MH @ 18-20hrs) and flowering (1000W MH @ 12hrs). Questioner implies a "Tricameral" type system very similar to the Kushti Box. Rosenthal replies that the system appears workable, but would retain only the cloning area and flowering chamber, allowing plants to grow from transplanting to harvest in a single room.
