This is the best cannabis book I have read! Mel Thomas is an ex commercial grower who served time for cultivating over £2.5 million pounds worth of cannabis in the UK! He has written a very informative and interesting book, that not only explains the history and uses of cannabis but also clearly explains how to set up and then manage any size of garden. I liked the fact that the book did not feel artificially padded like some of the US books, and the author focuses on what you really need to know to grow. The book contains excellent images and diagrams covering both Hydroponic and soil grows. If you're serious about growing then this book or one by Mel Frank, will set you on the right track.
