Roots need O2, not CO2. You want to have the CO2 around the leaves. The best thing would be to turn off your exhaust fan while you are making the CO2. That way the room fills with CO2, the plants consume it, then you turn back on the fans to exhaust the spent air.
dejayou30 Reviewed by dejayou30 on . Can I get a thumbs up on my grow plan? My current setup is temporary until my fogger arrives, but currently I have 6 small 360 degree sprayers shooting nut/water on 10 net cups setting on a 35 gallon res with maybe 10 gallons of water. I used hydroton by it's self as the grow medium, but I am wondering now if I should have used something in addition to hydroton. For now I will leave it alone I guess. The spray is on 24 hours with no rest with enough pressure that it covers the open portion of the netcup. I got these sprayers Rating: 5
