Morning O.F.C. !-- Time for da Wake and Bake !
Hey Bud are U pushing any air thru your boxes or relying on dissolved O2 ?-- My bubblers are not for oxygenating the nute water !-- I got 2 airstones in the bottom of my boxes pushing room air thru the boxes 24/7 !-- My pumps are on 15 minutes --off 15 !-- Plenty time for gas exchange --I have no idea how much if any O2 is dissolved in the nute water !---My plants get O2 from direct exchange from air to root !-- Been thinking about hitting some estate sales looking for one those O2 generators for COPD and stuff !-- Running a bubbler off it pumping O2 into the box !-- My res runs in the mid 70's !-- I hit 80 I get white slime which prevents the root air exchange !
