An interesting book, which outlines in detail the Sea of Green (or continuous harvest) method of marijuana growing. The trouble is it only describes this one method, based on cloning, which is for the big-time grower (ie seller). So if you're more interested in smaller-scale production (perhaps for personal use only), you ain't going to pick up more than a few hints about how to go about it. Moreover, some of the techniques (for example, the wick process) are rather confusingly described: I read one page five times and was none the wiser, even with the pictures. Overall, this is an enjoyable insight into one grower's world, but probably not for the first-timer.
