I guess I'm just more used to growing in soil. A quick search found most of the complaints for use in hydro pertained to algea growth (in the reservior) and clogged tubes and pumps. No pumps or tubes in my grow. Guess I'll just keep using the very small amount I've been using and I'm using Sweet, as well.

I was just going by Cervantes' statement that adding sugar (mollassas) during the last 6 weeks can enhance bud weight by 20%.
