Need expert advice on Co2 with DWC.

BigTigga · 09-27-2008, 04:54 AM

Too keep air pressure down in my grow space (Its a room with in a room). I want to put my Air pump in the grow room but do not know if 1500 ppm of Co2 will cause the roots to suck up less nutes because of low oxygen. I am doing a DWC with fog. I also Need my fogger air intake to be in the grow room to so pressure stays equal with outside pressure. I got the fogger thing figured out but just need some help on Co2 and roots.

I believe it does not matter. Tho that is only my opinion.

Plenty of O2 left, your not displacing much of the normal air (less then a percent) . I run mine at 1800 to 2000PPM in my small DWC grow.

So you say only 1% of oxygen is displaced by 1500 ppm of Co2. Nice

That is good then for my fog.

Any other experienced feedback on this topic!
