Mites! CO2 Poisoning

Hi everyone,

Just couple of questions about CO2 poisoning with a CO2 tank and regulator:

Should I leave exhuast vent (fan and light off, of course) so that the CO2 can raise and push out oxygen through exhuast vent when CO2 tank is running and building up at bottom of sealed grow cab?

With this first grow, I taped both intake and exhuast vents. But I think to tape the exhuast vent above plants is a mistake because there is no place for oxygen to escape while CO2 is being injected inside the cab and then sink to floor. I should have taped just intake vent by floor only.

I believe I should have all circulation fans inside off also so that CO2 don't get mixed with O2.

Thanks!​

Actually you shouldn't be pumping Co2 when the light's are off. Co2 if the other half of what the plant needs to grow. When you turn the lights off the plant won't use co2. You should probably just make sure you've got some circulation in there so the humidity doesn't spike and leave your plants at risk of mold and pests. When the lights are on you should still have some circulation to replace stagnant air but the Co2 will also keep the air rich for the plants.

Doesn't work. I had mine up to 5000 ppm in my closed room with the lights out and I did this for three days and when I went in to check they were worst than ever. Low temps don't work unless its 40 and bellow. Too cold even for your plants. Best vacume them up every day and harvest asap
