Sealed grow air scrub
Dankbudz84started grow question 5y 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.

Can I exhaust my grow tent into the closet it's in?I'm putting a 3x3 grow tent into a larger closet I have (maybe 8' x 4')? So I guess the closet is called the lung room? I will have a carbon filter and inline fan in the grow tent exhausting out. Can I exhaust out into the closet it's in? Or is that a no-no? Pros and Cons?Setup. Ventilation

Anyone tried a plasma filter instead of a carbon filter?Supposedly superior odor elimination over carbon filters
Look here. https://www.youtube.com/watch?v=kwiNUkjL1Dk
As you can see they resemble carbon filters (they're part carbon filter actually). The only question is...can they run 24 hours a day for 3 weeks?
Anyone tried them?Setup. Ventilation

Air-Intake / Equipment question.Ok, so i bought a air outtake system for my grow tent with a active carbon filter so my whole house doesn't smell like weed as it does now. My question is can i just install my air outtake in there and close the tent without having a air intake ? Or will that cause Problems ?Setup. Strain - Autoflowering

Odour controlFirst indoor grow and is a stealth grow. I’m wondering if complete odour control is possible for one plant. One auto in the tent with a large carbon filter and appropriately size duct fan, walls are sucked in — I also have ona blocks to place around room during flower.Week 3

High humidity in the morningI’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)Week 9

Cardboard box method for dehumidifierHi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?Setup. Ventilation
