Has anyone here read or heard about CCI The Black Book by Jack Whipple? It claims to teach you how to grow 3-4 pounds per light at a larger scale and includes strategies like crop steering and automation. Is it worth the price, or are there better alternatives? Buddy of mine brought it up to me and I said do not buy that damn book, but just wanted to see if anyone else here has heard of it, or has reviews on it. Can't find much information online.
