My friend has no co2 controller, just sets the flow-meter on the tank to 3 cu ft/hr and lets it run continuous (for the 12 hours lights on). Room is fairly sealed but has some smell/air leaks. The plants only had 8 more days of flowering and had red hairs, getting the final resiny-ness. A day after the co2 started, the buds were all shooting out new white hairs (a bad sign in my opinion, means theyâ??re stopping maturing and starting to grow new buds again â?? in week 8).

Could the co2 cause this? Also we worked in the room for an hour while the co2 was running at that flowrate; is that bad for your health, if so what does it do to you?
