That headline may sound like I'm trying to sell the book, but it really is a comprehensive, exhaustive and highly detailed reference manual that covers every aspect of marijuana horticulture from A to Z.
Over 500 pages (all in full color) and arranged in color-coded sections to help you navigate the abundance of information. I may be wrong, but there does not seem to be a particular order for these sections, but this book isn't meant to be a guide for novices that holds your hand in explaining how the plant grows all the way through to the harvest and cure. Don't get me wrong, all of that information and more is in the book, but it's not put together in a natural flow from equipment to seed to harvest. It's more of an encyclopedia that includes everything - you just have to find it.
Tons of color photographs and lots of great illustrations sometimes do a better job of explaining things than the text itself, but if you're a visual person like me, you're greatly appreciate that approach.
I dock it one star for two reasons. It has more than a few ads interspersed throughout the guide selling certain products. I've never seen that done and it seems like a biased approach. It's a $30 book, so the ads seem unnecessary. More importantly, I sometimes found it difficult to sift through 500 pages to find the information I was looking for. The info is in there, but given the sheer amount of information, you can spend a lot of time trying to find what you want.
I'm constantly referring to this book, so if you're serious about growing, you must buy this book. You don't need to read it cover to cover, but you'll need it far more than you think you will.
As I mentioned, this isn't a 1-2-3 "learn how to grow book" and that's a good thing. If you're just starting out or just considering building your own grow op, I highly recommend Grow Great Marijuana: An Uncomplicated Guide to Growing the World's Finest Cannabis, which is a no-nonsense guide to learning how the plant grows, what equipment you need and how to work through your first grow. You really need both books, especially if you're just starting out.
