Humidity problems in bloom
Plummstarted grow question 4 years ago
I have a 16inch fan outside the intake hole to my tent blowing air in, I have 2 clip on fans one each side of the tent and a carbon filter. There’s a dehumidifier 300ml per day in the middle of my tent. This is a 4x4 tent. Any tips on placement to lower rh? It goes high as 80%.TY

If you don't actually have an intake fan, get one, at least a 6". Sm RH of 80% is ridiculously high, unless the room outside of the tent is also 80%.
If you have an inline fan, make sure it's blowing out and your tent walls get sucked in a bit when you close it.
If the room outside is 80%, you'll need a new dehumidifier. Other than that you can defoliate. It will only drop the RH bay couple of points, but it will help protect against mold. Good luck!

I mounted my dehumidifier at the top of my tent to suck out more moisture. Rh sits around 57 or lower

Growtent Humidity controlHow do you control humidity/temp when using a grow tent? is it enough to put a dehumidifier in the same room as the tent and close the tent and just blow the air outside with a fan and tubing? Do u need an intake fan too? Or does the "good air" gets sucked in enough without ? THXSetup. Ventilation

Can't vent exhaust fan outside, is this a problem?I have my 2x2x4 tent in a closet, with a 4" carbon filter inside the tent and a 4" inline fan outside of the tent, exhausting. But I have no way of directing the air to outside or even out of the room. Will this be a major problem for me? Room is otherwise AC'd via central air.Setup. Ventilation

Would it be possible to have a closed loop ventilation system?My tent is in a garage that gets very cold, i need the fan running so i have constant negative pressure so there is no smell. Could i just have the fan extract back into the tent with a CO2 bag in there? Heat shouldn't get too high, and only other thing i could think of was CO2Setup. Ventilation

How to deal with high (80% ) humidity during flower without dehumidifiersFirst time grower,
I'm in W-Europe and will have around 21-27°C, 75-85%RH in my 70x70x160cm tent, Not more humid than air outside it.
Getting a dehumidifier isn't an option for me.
Any advice on how to still manage through mid to late flower from someone who's in the same boat?Setup. Ventilation

Best way to keep a tent in the loft coolCooling the loft... so I've got my tent in the loft, I have a 4" inline extracting from the tent and a 6" inline feeding air into the loft. This works perfectly the majority of the time.. I can keep things at 25°c with ease. But on hot days the tents gets too hot....

How to vent grow tent?Venting into large basement area separate from lung room. Averaging 65% RH in tent. How can I vent my grow tent out a century old red brick home's original basement windows discretely? Or, can I vent into an old (capped) chimney without removing the cap? Lung room is 6x10.
