Ah.. thanks!
I was thinking recirculating setup...
I never added anything to stimulate microbial activity in traditional hydroponics - as organics and hydro are often considered mostly incompatible - so you'll have to ask some of the other gurus. I do see that some herb growers use carbohydrates as "sweeteners" for final product, but I think that's a completely different issue. I don't think that would be of interest to a pepper grower.
