Thanks. I really need to do loads of research. I've been growing for about five years now or so, and have always used bottled nutes. I don't know shit about nutes. I just read the directions on the bottle lol. That sounds so sad, but its true. I also have loads of soil building up in the backyard from many previous grows. I just now am starting to look at ways to recycle, I should've done that years ago..that's what brought me in the organic section here. After reading some of the stuff in this section, I realize how little I know and would love to get hip on it all.
