Marijuana Horticulture: The Indoor/Outdoor Medical Grower's Bible by Jorge Cervantes is a pretty decent book. I went to Barnes and Noble to compare all the growing books to each other. So I decided to go with Marijuana Horticulture. It is colorful with plenty of pictures. It makes the books much more interesting to read, than most of the other books that will make you fall asleep after a few pages. I have never been so excited to buy a book in my life!!
