I think it's a great idea. You read posts on here all the time from people who probably didn't pay any attention to science in school who are suddenly eager to learn all they can about botany, horitculture, chemistry and physics regarding their plants, nutrients and lighting. Regardless of how you feel about the legality of using marijuana, I think that by growing your own you learn heaps. much of which can be later applied to other things or which extend your knowledge in general.
