it doesnt have a typical intake and exhaust like a portable ac.

basically the compressor outside sucks air through it, and supercools the freon, then the freon or whatever is sent through the piping, to the split portion that is in the house. then the air in the room is passed over the chilled pipes, to cool the heated air in the room. then the freon is returned to the compressor outside to be cooled again..

as far as the condensation and humidity is concerned, parts of the cooling apparatus are extremely hot, and evaporates the humidity and the condensation, or there may be a drainage system which drips the condensation to the outside..

im sure if you hit up google and did some research you could find an exact answer, and a more technical step by step process, but this is pretty much how i understand it from the ones i have seen

Dood i want mini slit so bad,but might need to just bite the bullet and get the window a/c as thats all i can afford right now,will that still do the job well? another issue i have is my windows are horiziontal sliding kind so could it still be mounted? argh!

Is it best to mount ac in growroom or in adjacent room and direct cool air in through wall to where its needed?

Basically I have an unused bedroom and built 2 sealed grow rooms inside the bedroom. So you buy some shelf brackets, and mount them where you want the ac to sit, put some plywood on the bracket and mount the ac to it. So the front half of the ac unit sits inside the grow room and the back half that would normally sit outside the window sits outside the grow but still inside the bedroom. The only problem I have is that the back that is outside the grow room puts out a lot of heat into the bedroom. A lot. Noise as well. They have the 'fan noise' quite a bit when you have the whole unit inside a room.

I use a 4x8x8 flower and a 4x5x6 veg. My ac's are only 5000btu each but I would have gone to a bigger unit for the flower room as there is a co2 generator in there, and it runs for an extended period when the generator gets going.

So I have the same AC room in room set up. I am experimenting with cardboard and dryer vent to tape to the back and run the hose to my AC exhaust vent on the wall. I am still playing with it but I think it may work. Please chime in if u have any info useful .

So are the dual hose portable a/c units pretty good at keeping the Co2 inside the room? Does anyone have any exp with these?

When you say "dual hose" units, are you referring to units that have one hose for intake, and another for exhaust, or just two exhaust hoses? I've been asking around too, but from what I understand, none of them claim to be completely air tight. I think I'm going to just call up a real HVAC company that specializes in medical type rooms to find out.

I am currently testing these units out. Yes, your guys are correct. They are not completely air tight, but the negative air pressure is a lot less compared to a single hose unit. Even window units still have some of negative air pressure effect.

In a pinch, dual hose units will work, especially if your area only gets a few months of hot weather.

Long term solution however, you need a split air unit or some kind of water-cooled unit stored inside the grow room.

i would advise using insulated ducting, as each foot of raw ducting will exponentially add heat back into your room

Where ever you hang the unit inside, it has a drain pipe that needs to go to the out side, the inside unit draws air from in the room, the only problem is getting fresh air into you room, you would need a dehumidifier and a indoor air cleaner, or an exaust unit that cutts on every few hours,

BayArea, I went onto the website you suggested - urbangrower.com - and although it shows at the top of the page "how to grow 2+ pounds per light, and how to use CO2, and how to do this and that" it just has a bunch of video clips showing him in Amsterdam and all kinds of other places.

Where do I click on "how to actually do it?" Is there something I'm missing here?

Your best option is to supplement the CO2 in the room. Window A/Cs exchange very little air if any. Any other method of replenishing CO2 will be counterproductive to the air conditioner.

What if there were to be good negative pressure on the room itself last light on chain open——> out window?

I have no idea how old this threat is I’m just in a very similar situation
