What size is your intake?

What size is your intake?

2 passive intake holes 8" - the sides of the tent are visible caved in

edit: opened the tent flaps all the way and it's still 87 - 88*.

Sounds like you're going to need to cool that intake room to like 65 max if not an open window you don't have much choice but AC. I'd feel better at 60 but then I'd be worried my roots are getting blasted with cold air.

Add a second exhaust to tent. First is venting cooltubes, second is venting ambient temp.

Look at this, if link works. It is TC 21 Thermo Cube. -

Put it at canopy level, to control second exhaust. It turns on at 78 and off at 70.

A humidifier goes a long way in my tent. It drops the temp a little and adds moisture to the dry air. I am maxed out on wattage so I just can't use an ac unless I turn off a light.

try to run your other fan as a intake.. see what happens . whats the temp like outside?.. that might help. over here its been only getting to about 70 max during the days.. and last night we had our first real freeze.. . I also run a flip flop. so 1 room is on during the night. other is on during the day.

The weather keeps getting cooler so i'm not going to worry about it for now. Won't be running at full 1000 watts for another week anyway- I'm still sourcing some clones and will give them a week of veg. Been downwatting intentionally to keep power usage/temps under control but also keep the canopy reasonably low until I'm ready to flip..

R u venting the air out completely or still by the window???? Did u get insulated duct... Judging from ur pick u can change ur configuration... Filter > cooltube-> cool tube> fan >out is one option that will get hot air from your lights n tent out n put negative pressure but still need cool air in...

 

[Ph-patrol]

How are you expelling the heat from your cool tubes in that setup.It looks like you are just pulling air out off the ceiling,Im not sure?

 

[california bud]

The pics didn't show the other fan venting the cooltubes, it's up above the camera near the tent opening
