Have you thought about splitting the room into 2? Flip-flops 12/12, only have 1/2 the heat created as well as more consistent demand for co2. I used to go this route just to skirt the nosy electric meter maid's questioning, but there are many things to consider.
If the room isnt sealed...i.e... not air cooled hoods and you are exhausting them... CO2 isnt going to do any good... you will just be exhausting it...Well this grow is for 4 people and only going to be a 12 plant scrog . Not my first go round nor a big profit project .. But yeah idk what to do then the room is built with 4x4 studs as frame, plywood for wall and 2inch insulation and I insulated all the cracks in between .... Also lights are not going to be air cooled ...?? Any suggestions on wich a/c will keep the room cool with the lights and everything also the temp will be more like 77-80 (going to use c02)

Yeah it'll be sealed , also I was told that the a/c recirculates the air in room nothing is going to be exhausted @Crab Pot .
Ok so as long as heat load goes im thinking I'm going to need about 2000 btu for heat load ,3500 each light x 4 so 14,000 lights, for the room im thinking 80sft x 20 btu so 1600 btu so I'm looking about 20,000 btu to cool everything ..?? I'll look into mini splits
Agreed if he uses a mini-split system. But if it is a window unit or a portable, which is what the OP referenced, exhausting is a necessity. Seems there is tons of help here, happy growing STLbudz.He won't need to exhaust externally if he has a/c and CO2. Should help with the stealth.
I wouldn't use a portable or a window unit. They aren't nearly as efficient as a minisplit. Minisplits are what most growers are using in sealed rooms. Plan on 4000btu for the lights only and 6000 btu for lights, CO2 and any other equipment that puts heat off.
This is exactly what I was thinking ! Just now literally!!! Ok new variable just popped up my garage is only rated at 30amps im going to need more than that atleast another double lol.??Two 12,000 btu 110v units would work.
Check out Mr Cool DIY Minisplits. I installed a 18,000 btu unit earlier this week that I purchased for $831 though Ingram's. They come prechaged with refrigerant so no need for a HVAC guy. They have a video you can watch of the install process.

I have a 10x10x8 tent that'll will be running 4000k air cooled hoods with to 8" fans 1 pulling 1 pushing outside room. I know how to set up but never worked in a big room like this . This flower room will be in garage in central cali wich can get 105 outside so for that reason I will have lights on at night . My main Q is what type of a/c is best in my situation ?
Ps I already have an lg dehumidifier
