Sealed grow air scrub

Dankbudz84started grow question 4 years 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.

Best way to cool your tent/ growbox?So I’ve built a custom growbox using an IKEA wardrobe, air vent for intake, two circulating fans, carbon extractor exhaust, and a 600W LED grow light. Temps average at 29 degree Celsius with the lights on full, is this too high? Best way to bring the temps down? Many thanks!

Humidity problems Can I have some advices on how to lower my humidity? I’m having some troubles lowering it since my plant is now flowering. Usually I can’t lower it from 60% while my temps are always on 27/28 C during lights on. I will leave a pic of my setup here. Should I change something?

High humidity during flowering I don't have an exhaust fan since this is my first growth and I'm quite on a budget my humidity averages around 65-75% I know high humidity increases risk of mould and bud rot is it necessary to get an exhaust fan and aiming for 40-50% or just risking the consequences?
