Sealed Room Cooling BTUS?

I've did some reading and plan to put (3) 1K Watters in a 9x9 Sealed Room. I'm on a limited budget for this room. Running lights off of electric is not an option. There is a 8'x8' storage room outside directly next to the 9'x9' Grow Room. I will be running a small inverter generator in the storage room that is barely audible, yet the room will be sound proofed and ventilated using fans and an exhaust from the generator venting outside the storage room.

My question is when it comes to keeping the room cool. I want to run Co2. Ideally, I would like to run (4) 1K lights. However, running (4) would cause me to spend twice the cost on the generator, additional fuel, and bigger air conditioning.

My question is, despite me reading 6k btus per 1k light, would I be able to get away with 5,000 BTUS per open light in a sealed room? The house is in a cool state, with temps. going from 10 degrees - 30 degrees during the winter. The reason I'm asking, 6k BTUS per light will force me to run an 18,000 BTU Window Unit. The only 18,000 BTUS window units I can find are 220V. However, if I'm able to run 5k BTUS cooling per 1,00 watts, I can run a 15,000 BTU Window Unit @ 115-120V. The house isn't wired for 220V in the bedrooms and this will save me from much trouble of re-wiring in a house that we are only renting.

Any input on this?

Thanks!

4k btu of Ac will usually work(never hasn't for me) per 1 aircooled 1k watt light, and I always go 6k btu per 1k open reflector.

So, a 12k btu(1 ton) window banger will most likely do the trick for aircooled.
15k window banger is cutting it close for 3 open reflectors imo, but I don't like cutting it close when designing rooms.

^^^^this is in a sealed growroom, taking into consideration of the ballasts, dehu/s, co2 gens etc.

If you plan to run co2 you will want canopy/leaf temperatures in the mid to high 80's.. plus you will want humidity at ~75 percent when lights on and 40-50 percent when lights off. If you are using air cooled hoods you can get away with 3500-4k btu per light, 5-6k per light if open hood. In my old setup I was running 8 1k's in flower and 2 600's (veg) (all air cooled) and ~400 watts for mothers. I also had 4 1/4 hp chillers, 2 dehumidifiers going and my 3 ton central air was just fine keeping it mid 70's. (no co2).
Look into a 18k mini split heat pump maybe. Easy to put in a 240 breaker in your box and wire it to run one, plus will give you heat for when lights out.

800 bucks, free shipping for 1.5 ton mini split heat pump
