You just need the right exhaust fan and the screen vents open in the tent and exhaust outside. Just keep the room it’s in cool and you should never need your other acs. Unless your room doesn’t have an ac. Then I would just fix the problems as to why it doesn’t have an ac and renovate to my specs.
Yea im good on the a/c, the room the tent is in is cool enough. It's a window ac unit. Just curious if moving my dehu outside of the tent would be an improvement at all

Hey guys, please please please give me some advise as I have a major issue with temp & humidity. In my country temp is 32 Celsius and humidity is 85% 🥵
I’ve placed my 8x6 grow tent in a room which is air conditioned. Now I’ve managed to get the temp down to 25-27. My grow tent pulls in fresh air directly from outside of my home. Hot stale air is also vented directly outside.
My problem is to bring down humidity to 50-60%. Since the tent is constantly pulling in fresh air from outside which 85% my Airconditioner cannot seem to bring down the humidity. If I off the exhaust system I can hit ideal humidity leveled but sacrificing fresh air coming in. Is this okay? Any other solutions? I hope someone has had this problem before and knows a solution 🤗

I've read through your thread completely. There seems to be one part everyone has missed.

If the outside air is 32c (about 90f) and you're trying to keep the tent cooler than the outside air, let's reconsider what you're doing. As stated several times by multiple posters, remove the dehumidifier from the tent. Use it in the room with the air conditioner as has also been stated.

Disconnect the outside air. Do not use the super heated source of air. Instead draw the air from the air conditioned and dehumidified room. Continue to exhaust your hot air outside as you're currently doing.

I actually have mine in the tent and the ac outside of the tent which would contradict my advice above. But my thinking when I set it up was that my tent was considered big. Its a 10x10, is that big enough or do you think I should place it outside still? Your comment on the sensor placement is kind of a concern so thought I would ask if my tent is large enough.
Yeah a 10x10 I'd say is definitely doable for inside brother.

Ok let me explain. Sensor placement is key... so if the placement is not proper your not going to have accurate readings.

If you run ac and dehuey into the tent the air cannot mix well before its sucked out. So while the sensor at the top says it's fine. Inside the plants it's likely not. Bug tents are an exception as it takes much longer to exchange the air.

You want the air that being pulled into the tent to be already conditioned so that you have the entire tent even.

A dehuwy in the tent will be hot by the exhaust. Ac will be colder at the point of input doing this creates uneven environments in the tent.

If it's pulling in preconditioned air then tire tent will be even.

In a small tent there is not enough time for proper air mixing .

It's most important to have good air mixing under and through the plant's as this is where the leaves transpire and where it counts.
Hey bro hope all is well, i got a similar problem except no tent only 10x9 room. I have window ac w/ inkbird humid control. a 4"extractor high in the corner wall (currently not connected carbon filter only bug guard). If i keep extraction on it pulls warmer air forcibly in making the ac work harder, so how much air exchange do i really need when the ac keeps temps & rh stable? Should i seal the extractor and draw air from the house or keep extractor on intermittently? Currently the room has natural neg. Pressure & pulls air via extractor when its off or when i open the door. Gonna put co2 bottles in also so can i exchange air less? Tia

Especially when it comes to CO2!!😉

So to summarize......prepare the air in the lung room so that it is ready to provide the proper environment when it gets pulled into the tents environment making it immediately available to the plant rather than only sometimes if it's not properly mixed?

OP close outside air inlet and use prepared air in lung room as air source. Using outside air means your at mother natures mercy for temp and humidity. By cooling and dehumidifying the lung room air you are better able to control the environment within the range that you are looking for.
