Got a few questions on how I should cool my sealed room...

My room is in the lower level of a building (basement),the room was originally used as a cold storage room.the room is built into the side of a hill and gets no direct sunlight.

The room is 10' x 15' x 10',with an adjoining room appx about 10' x 5'

Do I need to go with a mini split system or could I use a portable unit or window unit vented into the adjoining room?(adjoining room is also sealed)

BTW i'll be using 4k and co2......and will not be cooling the lights

Ok, Hi everyone.
I read the thread and I didn't catch this info.
The room I'm building has one intake and one exhaust manifold for the air-cooled hoods. My plan is to hang the ballasts inside an insulated box within the room. It'll have a duct running to it and one running from it, just like the lamps. In other words, I'm planning to cool it with fan-blown air from outside, not the aircon.
Anyone see a problem with this, assuming sufficient airflow?
I had another question, but now I can't remember. KO Kush.
Thanks, SW
I remember the other question. How much impact will insulated ducting have on coolness? I have to run a lot of ducting.

need a little help please, 13 x 13 x 8 room inside of room

r7 insulation between old wall and new wall and r13 between the studs of new wall

panda film, completely sealed room

There will be a 4x5 veg room with a 2 bulb 4' shop light for clones and 432w 8 bulb t-5 in this room as well as all the ballasts, co2 tank, a/c (window w/ ac box) and dehumid

2x 1000w, 2x 600w for flower side of room, the lights will NOT be air cooled, the hoods will be aaw's

on the hottest days of summer it reaches around 95-100 degrees and I would like to keep the temps around 77-82 give or take a few degrees

from my calculations I need either the 18k btu or 24k btu window unit but I dont want to be short cycling or get too large of an a/c, so what do you guys think?

I think a split is always preferable.

A fundamental premise I can't quite figure out is if these calculations are meant to exchange the heat of the bulbs whether or not they ultimately have air cooled hoods.

My system as it stands now is venting 3K of lights from an outside room through the lights and up a chimney. But all this reallly does from an Hvac perspective, is move 600 cfm through my house on a constant basis, like leaving a giant window open, so now my basement gets hot in the summer whereas it used to stay cool.

Should the ac be sized to exchange the heat of the lights being vented back into the outside room, instead of up the chimney?

how much does that cost to ru 1 - 5000 btu per 1 k together ???

questions on how I should cool my sealed rooms

i did my 4x5x8 veg room and a 7x5x8 flower room. inside a garage
gets no direct sunlight. the only window 3x6 is facing neighbors house.

should i get with a mini split system or could I use a portable unit or window unit or a bigger unit?

and should i get a total of 2 units or 1 unit? im more concern as far as electricity per month rather then initial cost of product

will be using (4) 1k hps for flower and (2) 1k's mh for veg (atleast 1k)

will be using air cooled hoods magnum 6" (should duct /exhaust with ac or just a fan pushing for just the lights?

the total room size inside garage is 11ft x 12x8 single stud 2x4 but only using 4x5x8 and 7x5x8 the rest wall/room is for me

used homedepot insulation and drywall pasting on edges and then drywall sheet 5/ 8 .

should i vent or get dehumidifier and ac?

Great reference, thanks!

Thanks 00420, Great information here, thank you for sharing it.

I just want to say thanks to IC mag for all the info over the last few years!!!

I just picked up a 20 seer 12,000k btu mini split system at the SD hydro expo. I'm planning on running this unit to cool 4k of light that will be air cooled with 200+ cfm per light.

The ballasts will be in another room with a window unit on a flip flop system with an a-joining room thats gonna be cooled with a 24k window shaker

I fear is (not that big of a deal) that the 12k mini split wont do the job all the way, and I may have to put in a window unit to help it out.

Any feed back?

The ambient temps are hi 90's durring the summer months.

Thanks IC MAG!!!!!
