My two cents worth.
that much air and 1200 ppm amount to an aeroponic system running 24/7

back off the nuits to 300-600,maybe cut the air flow by 50%
Daddynobucks Reviewed by Daddynobucks on . Is Too Much Air in DWC Possible? Is it possible to have too much air in a DWC bucket? I have a 19W industrial pump running two 4"x1" cylindrical air stones in 63-68 degree water and my roots are still rotting. Is it possible I am proving too much air where the roots can't get a grip on the bubbles or something? Rating: 5
