How to reduce humidity in my grow space?
Faegrowsstarted grow question 2 years ago
I'm just an amateur and am growing in my closet as I have very limited space. It's a small space in which I can't cut holes or openings. I use a small fan and a air purifier. Should I get more fans? Does a carbon filter or inline duct help if it can't exit out of the closet?

I would simply open the closet door and keep the fan and dehumidifier going... I'd prefer loss of light to risking bud rot which you're doing if the humidity is really high.
Good luck!

An extraction fan is the only option to reduce heat imo. Plus the benefits of fresh air for the plants will be rewarded. I've done closet grows, it's possible to make a exhaust system inside one. Cheap enough fan and filter will help you loads mate.

Air exchange/replacement is the only effective way to reduce humidity.
Recirculating the same air in a closed closet, no matter how much, will not remove humidity effectively, you need to get fresh air in there.

either have to exhust to a different area that won't comingle or get a dehumidifier.
circulation fans will even it out throughout volume of space, but won't reduce it.
leave small space open during lights on.. if an autoflower leave it open all the time. could grow only during certain seasons to avoid it. If ambient RH is high and your plant is transpiring as it should, it'll always be ab it higher than ambient RH%. A furnace being on dries out the air. AC too. but, you need a dehumidifier for any major issue.

Intake Fans / Opening Lower Air Ducts or Back Flap?I'm researching intake fans and/or opening lower ducts to pull air in. I never worried about intake in the past, I just made sure my fan up top was sucking air out of the tent to create negative pressure. Thoughts on intake fans or having the back flap of the tent open? Thanks!Setup. Ventilation

Now getting condesation in my tent when I've added this duct to a pipe exiting the house? Am near harvest too.Didn't have an issue with condensation inside the tent before, now that I've attached the duct to a pipe going out i'm getting condensation inside... Does the set up look right? I've hooked up to a smaller tent too via a T. Could it be pressure?

Sealed grow air scrubAfter 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

Lights airstone c02What light to plant distance would you set it at? The only test I've done is at 25 inches its stable at 80°f and 75% humidity. When I lower it to 18 inches, the tent read 85°f and 73 humidity.
Other question I have is what's your favorite air stone(disk)?
Lastly, add c02 yes/no

Extraction fan runningI have a Ambient Q60 tent... When I cover up the air intake holes during light off hours and want to leave the extraction fan running, the air from the whole tent looks like its being sucked out. There's no room for air to get it. Am I doing something wrong?
