Reddit reviews DIY Autoflowering Cannabis: An Easy Way to Grow Your Own (Homegrown City Life)

Ed Rosenthal's Marijuana Growers Handbook is good. It has quite a lot of info, though only a passing reference to autoflowers, and I find it a bit strangely organized at times. Quite a bit of the info will apply to autos, so you might want to pick up this one and then supplement by reading about autos here, on Autoflower.net, and/or with the Lowenfels book in the next paragraph.

Jeff Lowenfels just released DIY Autoflowering Cannabis: An Easy Way to Grow Your Own, which is specifically about growing autos. It's written for a gardening audience, someone who might be used to growing tomatoes or other flowers and is curious about branching out to cannabis. It will probably be helpful, though if you have zero gardening experience it may gloss over some fundamentals, and defers to other sources (such as the Ed Rosenthal book) for some details that aren't auto-specific. It has a lot of breadth, but less depth than I'd hoped -- though I'd already done obsessive research into autos, and I'm not really his target audience.

Jorge Cervantes has Marijuana Horticulture and Marijuana Grow Basics. The latter is a more beginner-friendly and slightly updated subset of the former, though it doesn't have anything about outdoor growing. These also have a lot of info, and could substitute for the Ed Rosenthal book, though they're showing their age a bit.

cart_crasher recommended the Mephisto Grow Guide. That's pretty short, but has some helpful auto-specific suggestions. Probably a good supplement to one of the other books. (I've also been really happy with their autos.)

People will probably recommend Grow Weed Easy (a website), but it's been wrong about enough things that I don't trust it. I'll leave it at that.

Comes out in October though...
