How to keep grow tent cool in the winter

Hey guys

I am having troubles with my window A/C already this year due to the freezing temperatures outdoors.
When it gets cold out, my A/C freezes, and the room gets pretty hot with the HPS on.

What can I do to keep it cool in here?

That's an interesting question. how to keep an AC running when it's freezing outside. I wish I could help. Only thought is to get a large vortex fan and run that from your window.

I'm guessing that neighbors aren't a problem otherwise they would wonder why you run your AC in the winter.

Brilliant! Thanks

if you have sub freezing tempts outdoors why not do a filtered air exchange with outside air ? Save you electric costs, and keep temps down. CO2 sealed environment would be only reason I could see to not utilize the outside cool air.

Yes ^^ why would you try to cool already cold air?

I keep it on the fan setting, i only use it to pull in the outside air

Use a cheap inline fan at the grow room pulling outside air in. They're like $15.

most window ac units in " fan " mode run the same as in ac minus power to the condenser. So you just get inside air recirculated.

If you are open to the idea something like this and stretch panty hose over the whole rig.

Hope my input is seen as helpful and not nagging. :0)

i use a little duct fan for fresh cold intake from outside. Id directly cool my light with it but pretty sure the moisture would destroy everything. I use the window fan seen above to help exhaust instead of directly connecting the exhaust ducting to the window.. i figured it looked less questionable seen from the outside as I am in an apartment complex and people have these in their windows all the time.

to answer your question ya just use a little duct fan directly connected to your window for intake

cheers

just run some duct from your window to your area bro if you can leave the duct up high so the colder air can sink down to your plant space plus itll have the added benefit of helping the heat rise

run a portable ac unit and exhaust that out your window. my portable ac runs 12hrs a day 7 days a week year round. mine exits like a dryer vent.

pouring hot water outside in freezing temps is not a great idea imo. eventually the water is gonna freeze, and im sure some of that water had made it into the cooling fins, then when it freezes it can split metal causing your ac to break down.
