I got 3 quest from 105-300 versions of them and they run 24/7 , good luck with the small ones . Plus they are gonnea produce tons of btu heat in the grow room. If u brough in cold air into lung room on a temp controller with in-line and ducting and to make sure rh is ur desired use the dehumidifier in there . Just saying having it in the tent is gonnea be if not one of ur biggest enemies

from tents to outside, air is drawn from my attic which isn't exactly sealed. weather is wet rightnow
Yeah if you're drawing air in from outside (unsealed attic) and venting it back outside, it's definitely gonna be hard to control the humidity.

Any way to intake/exhaust to/from the living space of the house? The air will probably be less humid to begin with, and it's easier to dehumidify if you're recirculating the (mostly) same volume of air...

I think I could do one or the other especially in winter. Issue is ect noise so sucking it up through a cupboard is definitely possible.

I was wondering if it would better control my environment to just flow fresh air over the top of the tent above the lights. Aka have the In and out inline with each other high up. I use external filters and fans so it's just a duct hole

I do wonder if I did that it would create a stream of airflow at the very top of my tent , removing head but enabling me to supplement with some co2 at the bottom of the tent

So if you bring humid air into the tent and exhaust it outside (which is what it sounds like you're doing now), then your tent is going to be humid no matter what. The dehumidifier(s) inside the tent will fill up, but the humidity in the tent won't go down because you're exhausting the dehumidified air out and replacing it with more humid air from the intake.

When people talk about a "lung room," that's basically the space that your intake is pulling air from (in a lot of cases the "lung room" is just the room the tent is in). You want the air coming into the tent to be less humid to begin with, which may require having a dehumidifier in the lung room.

You can also exhaust back into the lung room and the dehumidifier will remove the humidity that gets generated by the plants.

To address the noise, you can put the fans and filters inside the tent if there's room. Also, not sure if you're using an intake fan, but in a tent you can usually get away without one.

Hope some of that helps, good luck!

Thanks for the reply. i will see if i can intake from an area in my house. The air will end up being quite warm though . The fans don't make too much noise its just a compressor style dehumidifier thats really noisy .

Hey if it's a comfortable temperature for you, it'll probably be fine for the plants. And the faster you can exchange air in/out of the tent (by turning up your exhaust) the closer the temp and humidity in the tent will be to that of your house.

If it's not very humid in your house (or lung room) you might not even need a dehumidifier. I have one in my basement near where my tent is, but it's been there since before I started growing, because my basement is unfinished and gets really humid when it rains. If my house were sealed better or I lived in a drier climate I might not need one at all.

I've been able do decrease the humidity and the results have been amazing look that.
Eyyyy looking good bro!

Thats one thing my buddy who took me under his wing taught me , ALWAYS use a dehumidifier , they work wonders for resin and trichome production and of course keeps the mould at bay.

Keeps em warm at night in winter too

Bringing in cold air into your lung room will generally raise your RH; cold air holds less water, so for same absolute amount of water in the air but lower temps then RH goes up.

my point was u could use outdoors air exp if u are limited to a/c power/budget and def cool the room off, if led’s u want 80-84f canopy so if ran on cycle on night I don’t see it being that hard , you would just need to have that extra deh power and also controllers to make it work. If your in certain zones like Colorado and that area would be so dry u wouldn’t even prolly need that much deh . I run sealed rooms with mini splits and def still need deh power to keep the room exp in dark cycle at correct vpd.

You should de-foliate the bottoms of your plants. They are transpirating (transpiring?), breathing and creating humidity.

A bigger and better de-humidifier, yes it helps. Keep your tent door open after you feed.
