I know a guy who's been growing for 25+ years and he swears by H&G, he said when he first switched he couldn't believe how much better it worked, he uses the full line with the shooting powder and said it produced the fattest buds he's ever grown indoors, I don't remember what he was using prior to H&G though, I'll have to ask him the next time I go help him trim, my hands are cramping just thinking about it, lol.
