why not do an air conditioner? duh, it dehumidifies and cools too!

but it wouldn't really work since the duhu has one fan it shoots the from you grow past the cold cools across the hot coils out of the grow room. or in the other direction where you would get hot dry air in the grow room. just put the dehu in the room

I'm setting up a new room in an unattached garage I will be running an ac window shaker but I'm afraid I will need more. In the summer the outside humidity runs above 80% most of the time and temps 80 to 90 degrees . It's the dark hours that bother me the most. I would rather have it installed now as I am building the walls, then have to add it later.my research tells me to mount it as high on the wall as possible. Any thoughts?

I don't want the ac fighting the heat coming off the DH.

If the ac is large enough it will cool and dehumidify during the lights on period and the DH will handle the dark hours.

I'm a believer. Thanks! +rep

6000-8000 btu AC might work good with increased air flow

Whats the formula for sizing? my room is 16'x 8'x 8'. 2"x 4" stud wall construction with a vapor seal and R-13 insulation. Drywall ceiling with two layers of R-19 6 1/2" insulation. It's built inside a block walled garage. 2800 watts of lighting total. All HID's are open Bat wing reflectors. Veg are t-8's digital ballast. No CO2. I'm looking at an Ideal Air 16,000 BTU Portable I want to size it for the future addition of a CO2 burner and a dehumdifier. Is that big enough? I also have framed in a spot for my 10,000 BTU window shaker. I would rather only use one or the other. Any help on this design would help!


Thanks! Hucklberry

These are for portables, the window ones you would be able to do 1 or 2 lower. Prolly whatever your wiring can handle and electric bill can afford would work good~


  • 7,500 BTUs will cover 150 square feet x 8-foot ceiling = 1,200 cubic feet
  • 9,000 BTUs will cover 200 square feet x 8-foot ceiling = 1,600 cubic feet
  • 10,000 BTUs will cover 300 square feet x 8-foot ceiling = 2,400 cubic feet
  • 12,000 BTUs will cover 400 square feet x 8-foot ceiling = 3,200 cubic feet
  • 13,000 BTUs will cover 450 square feet x 8-foot ceiling = 3,600 cubic feet
  • 14,000 BTUs will cover 500 square feet x 8-foot ceiling = 4,000 cubic feet

I got a 10,000, (maybe 12,000), Btu portable that heats, cools, and dehumidifies I want to get off of.
It's missing the caster wheels and the vent hoses; but works real good otherwise.
110 volt plugs into regular outlet. A hundred and a quarter and it's yours.
If anyone interested I'll snap a couple photos.

It's a Fedders 9,000 btu for cooling. I'm in O.C.
I got it sitting on some aluminum rails because the casters are not there.
One wheel broke and I took them off to fix and then lost them.:wall:

I just tested it as it hasn't been used too much and is blowing cool air real nice.

I don't have the vent hoses or the window thing where they hooked up to.

Do these figures consider the amount of heat produced by your lights or just the average house room?
