Sealed grow air scrub

Dankbudz84started grow question 4y ago
After adding a dehumidifier, evaporative cooler and c02 bag I decided to go ahead and do a sealed grow to better control the environment. Conditions look great. I’d like to know if I can loop my exhaust to recirculate the air to scrub it when things get stank? Video on the diary

A supply of fresh air is vital when your not running your c02. Plants put off oxygen and breathe c02. So in a sealed environment when c02 is not running and you recirculate the air it would be like putting a bag over your head. This time it would be oxygen building inside the tent instead of the co2 they need to breathe.,Cheers

I am adding C02, I have the ability to maintain a perfect vpd at all times, I also walk in the tent at least once every 2 days maybe they are getting their fresh air there. I don’t see how this would be bad, I have humidifier, dehumidifier and a/c.

No, it wont work. Without fresh air exchange your plants will die. Plants need both oxygen and carbon dioxide to survive. You can not grow healthy plants in a system whereby there is no replenishment with new air.
