| Somewhere on this site there's a post describing the contents of Super Thrive. Basically it's a mix of B vitamins (which it smells like) and rooting hormone. It's unclear to me whether the B vitamins add anything. So far, I'd say my plants are perking up more clearly under a regimen of worm tea than they ever did with the periodic dousing of Super Thrive, but I don't have controls. -- Bill |
