Yes
Tent vents provide intake.
4x4x6.5 tents need more openings, else forced intake.
Zipper “relaxed” (open, partially).
Yes, bottom intake and top exhausting is most efficient.
Cardboard is a great trick to reduce humidity in that area while not exposing yourself to elements or upfront cost.
@PharmerBob That’s a great idea! Just to put up sheets of cardboard on the walls etc.?
@Hopalong i would set up duct fan to take exhaust the air in lung room to outside
@Reed71 Thanks, let me get this straight, vent the tents normally into the lung room, and just having an exhaust air valve in the wall?
You can exhaust air from tent to go outside or set different fan to exhaust air from lung room to outside if you put one in lung room set up in ceiling highest point to get hot air out where i live in winter humidity is hard to deal with during this time of the year @Hopalong
Dehumidifier outside tents will also warm that air making it easier to maintain good temps in your tents and you could put a humidifier in each tent.
Venting out has done nothing to my RH. Venting in can change temperature and humidity though.
Good air flow and circulation is the best to fight humidity, for me at least, and sometime venting in when outside air is right temp and humidity to help my interior
Actually I just ordered a 20 liter dehumidifier for my lung room just last night. I’m going to vent in the room and just try to go with the dehumidifier there and do the vent out in the summertime.
I have humidifiers for my tents (smaller tent is running at 75% now, seedlings), and that’s what is raising the humidity in the room. After i drop the humidity to 60% in that tent I should be good I think. Also the coldest and driest season is starting now.
Cool
Lung room dehumidifier supports two 4x4 tents.
Yes, add temp (4F).
Yes, reduces RH.
Yes some tent exhausted (my isolation means no filter required for attic release.
Yes Lung room circulation utilizes tent warmth to support temp/RH stabilization.
For the life of me, I can’t fiqure out why I have one tent 15%RH lower that the similar tent. I amove plants and saw no change.
Swapping lights is next, what a pain, that will be.
That is a head scratcher, I run 3 ACI controllers as well, and I’m wondering if swapping the sensor probes might be an easier experiment?
I have previously done the controller probe chase routine.
First introduction to two controllers with probes (never stayed the “same” ).
Probe swapping would be good, but the Govee Temp/RH-blueT, confirm temps and RH. I actually use the Govee numbers to offset the AC-I T/H cal.
Pondering the mystery, smoking more, it occurred to me, it could be the corner with two freezers.
Both tent ON, numbers can work.
I keep trying to push on the icons to check the settings.
The piece going through wall is 3 pieces, 2 dampers because im venting portable ac and charcoal filter and inline fan to the outside
Be careful venting warm air into an attic if you live in a cold climate where you get frost or snow. There are some great pictures from the Police departments who regularly catch grow houses because that house has no frost, ice or snow on the roof but every other house in the street does. The heat causes the frost, ice or snow to melt and the house has no snow on the roof. The Police simply drive along or fly over the area and pick houses that have no snow on the roof. The next day they are at your door and your off to jail.
If you are going to vent warm air into an attic, make sure the roof has decent insulation under it so snow can form on the roof and not melt due to heat in the attic.
For the OP, get a big dehumidifer and have it in the room with the tents. Increase air flow through the tents too.
I have a 12x12 Grow area with a 4x8 tent. I installed a dryer vent in the wall. I have a window I open slightly to let in fresh air. I adjust my exhaust fan according to needs. Most of the time it’s on level 3. A room dehumidifier is outside the tent. I have a humidifier from AC Infinity inside the tent. It’s in the teens here outside. AC Infinity also makes a window kit. My exhaust fan is 8”. Not sure if any of this information helps. Good luck
@randylilgnome That’s my plan exactly, the dehumidifier is in the mail already… the humidity is in pretty good shape now even without it, the weather outside is cold and dry…
Vent thru attic to an attic exhaust vent (secure hose to vent straight out).
Gable vent?
