wasn't adding oxygen because of stagnation, I have grow many different styles of hydro and oxygenated water is the most important part of hydro. plants need the oxygen and thrive when you increase the levels. Maybe i'll build 2 of the tubs and oxygenate one of them to see any differences there might be. I'm growing bell peppers right now for my g/f in a nice dwc(deep water culture) set up. great quick results. Plus it would also be moving air up and out threw the double wall which might aid in cooling. indoors I have also cooled the air pump which cools the air being pumped into the water which will cool the water in the res.
