This is my third year outdoors, and I've got a bit more confidence... thinking of trying organic. So far I read EJ is effective and reasonably priced. I'd like to find a program that's laid out clearly. I found this for EJ: http://www.hydro-organics.com/home/index.php?categoryID=558 Is there a better line? Easier to do, cost effective, etc? I'm growing in a decent compost mix with a bit of pumice etc so it will drain well, in 100 gallon soil bags. Please post links or books, I like reading. The thing is, though, even after i stuff 999 details into my head, I'm still usually looking at a gap between that and knowing exactly what to do. Also, what tools do I need -- such as a 20$ or a120$ PPM meter? And for a pH meter? Etc?
