heres a interesting fact

did you know that large dehumidifiers give of heat dirty bastards i figured they gave off coolair as an ac dehumiifies as it cool heat stressed my ladies last knight fuck me theyll be fine but that what i get for thinkin the lit withthe unit did not say any thing about discarge air hot or cold but i have to fight it with 12,000 btu ac so i figure its about 12,000 btu of heat come out wtf change the dynamics of the room quite a bit.

its a 70 pint fidgidaire unit gota smokin deal 135 shipped brand new. and is a heater will be nice if the winter here will come a stay one day it 28* the next it 70* fuckin SoCal.

you sure it isn't the ac itself? cause my 6,000 btu blasts hot as hell air out of the back, so your 12k would be double that. do you have the whole ac unit in the grow room or is the back sticking out (like it would in a window)?

im for sure thanks thu good one

Yeah they discharge hot air by principal of how they work.. You need to do a better job managing heat in your grow room. I am in SoCal I have a 15,000 BTU window a/c unit, with a butt box. 2000w lights, 50 pint dehumidifier and a 4 burner CO2 generator.. My a/c runs every once in awhile or all of the time if the generator + dehumidifier is working.. You can't water cool the dehumidifier, or have the hot air blow out of the room.. Either of these things will make the dehumidifier ineffective

I just ran my air conditioner/dehumidifier exhaust hose right to my carbon filter which then cleans and shoots out the hot air.

Putting an A/C in a room without venting the hot air increases temperatures. An A/C works as such, a liquid evaporates into a gas, extracting the heat from the air around it. Then a compressor pushes this gas back into a liquid. This process always creates more hot air than cold air, you just displace the hot air outside your grow room. OP, a dehumidifier uses the exact same mechanics as an air conditioner, only the hot air isn't vented anywhere. Basically, next time buy a air conditioner with a dehumidifier setting on it, you'll save a ton of money on electricity by only having to run one unit. Plus you won't have to run your A/C more just to cool the dehumidifier.

I got really lucky living where I am. The coolness of the winter time has been keeping my humidity around 30% to 40% recently. The water freezes right out of the air and the low temps keep evaporation down.

I had been running a portable 9,000 BTU AC unit, removing probably 10 liters per day, and I couldn't keep the temperatures or humidity under control with that thing. POS broke after 2 weeks anyway. So I opened the widow to let in some air from outside and my temperatures basically dropped too far, running 65 degrees in my 2x4x5 tent with a 400w system and a 180cfm blower. I don't even have to ventilate the room outside, having the heat from the lights blowing back into the 10x12 bedroom is the only thing keeping the temperatures in there reasonable.

In the summer time things are different, I need a window AC unit for sure, but during the winter time... If it is cold enough, just open the window and freeze the water out of the air. Works great for me but it really depends on where you are in the world.

i was doing good similar with just pullin 35* air in with the light ducting and cooling the lights and the room would stay at 80* withthe 35* outside temps on the walls, but we had a heat wave and now its 65-70 above 45 all night with a rh of 70. and bith conditions caused major condisation on my ducuting and the dehumidifier cured that problem quickly but added tons of heat, and i had the ac disconnected from the sentinal control beacuase i was upgrading the contactors so i could run both ac off one contactor rather than 2 and was not in any hurry and drop the ball on this heat stressed them pretty good 93 max is recorded for 2hrs with min RH of 25%, plugged in 12000 btu portable and wamo heat gone along with the other 25% of rh rewaterd. the ladies did not mind all that much but man the dehumidifier sucked the water right oput oif the pots.
