I managed a book store for many years, and we sold a large variety of books related to growing, no prob. The funniest question I got was a man asking for a book on how to make money, so I took him to our business section. He looked rather confused and said, no he wanted a book on how to MAKE money. I laughed and said I'd never seen a book on how to counterfeit. Pretty sure that kind of book would get you into trouble. Good luck, cheers.
