May I ask why you are wishing to go "organic" and what the term means to you in regard to gardening? It's really such a loose term and I've seen multiple definitions, some of them outright dogmatic, on this website alone. Are you essentially wanting fertilizer derived from natural materials as opposed to being made synthetically? There is some debate out there that many of the materials used in hydro nutrients can't qualify as "organic" because the methods of harvesting the materials are too detrimental to the environment. I read that in a magazine, so I'm sure it's true. . .

In answer to your fertilizer question, Botanicare boasts being organic. I use it on bell peppers. Not because it's organic as much as it seems the peppers thrive best with that stuff for me. That's just my experience, though. It's expensive, in my opinion. But, I get awesome harvests from each plant. I use it as a fertilizer for my potted peppers, too. That's also hydroponics, I'm just doing the work instead of a pump. I also experience a lot less pH fluctuation with Botanicare. And no, I am not affiliated with them in case I sound like it.

I have read that Bio Bizz is made up of dissolved salts and this makes the use of EC meters pointless. It's not that there aren't salts. Just not dissolved. I may be way wrong on that, though.

:O)
