Agree about Green's Bible is the "go-to". Also, Cervantes book, Marijuana Horticulture. Excellent resource.
The New Cannabis Breeding is an ok book. Found several typos. Maybe better editing, yet the premise is good.
James Loud supposedly had an auto breeders book, yet hadn't had it released.....or at least the last I checked.
I think pod cast and You Tube if the reputable breeders are on it. Dude Grows, Dunn another.
Immerse yourself in many facets and keep a log book of grows. <<<<Essential!
