15'x15'x8' bloom room heat problems

My bloom room is 15x15x8. I currently have 3 1000w air cooled with a 12" inline for with a 12 to 6 reducer. I know I'm losing a lot of cfm with the reducer but I had the equipment for it already. I have a 6" inline for intake. My temps right now are around 82-88. (Too high).
I live in michigan so with winter coming I plan on adding 3 more 1000w.

I'm looking into a 14,000 btu portable ac, but I don't want to buy it if I am not going to need it during the long winter.
I also don't want to buy it and then find out it's not enough to cool 6 1000w even in the winter.
Any advice is greatly appreciated.

but im sure your AC unit will cool it down. with winter coming you may not need it, but adding more lights its hard to tell. i would say and im no pro, try adding the lights first, then see what the temps are, if they remain in the 82-88 range i wouldnt bother with an Ac unit especially if your CO2 enriched, if not maybe spend that money on a nice propane burner to get your PPM in the 2k range (i think 2k is the optimal for higher temps but look that up)

I'm not currently running co2. I've been looking into it. And I would need to either get climate control or run my exhaust and co2 regulator on timers.
It just seems really inefficient to run co2 and exhaust. But maybe if the timers are set up right the room could fill with co2 and then the used up co2 would get exhausted.

Co2 and using outside air to cool 6 1000's in a relatively small room is a recipe for disaster.

Don't waste your money on an air conditioner designed for bedroom comfort.

If you plan on using outside air for regulating temps, plan on some sort of temp regulation system.

Also some sort of distribution system for cold air, you won't be able to dump sub zero air confined to one spot on the grow.

the problem with pumping in cold outside air is that when it hits the hot air from the lights, you get massive condensation. no bueno.

a big portable AC might work to cool everything down nicely, since they also dehumidify the room. especially with the lights being air cooled it might work.

is there any exhaust system in place, besides the air cooled lights?

Don't have the air intake for the lights suck directly from outside during winter.

Have some sort of distribution ducting setup, this could be done many different ways.

Something has to be setup to regulate intake fan to temp. I'm thinking thermostatically controlled intake fan plugged into variac, and a thermostatically controlled passive exhaust dampener would be easiest.

I have a carbon filter>inline fan>lights>outside

The intake comes in through an inline with a hepa filter on the opposite side of the room.

There is so much about this that concerns me I'm not sure where to start.

1. Six kW will not light that whole room worth a damn- it will only do half, and barely that.

2. Bring cold air in and condensation becomes a monster you must tame. Do this on a separate air circuit from your lighting and you could have free AC, like my buddies in the Colorado High country do.

3. Do NOT run the cold air thru lighting ducts... bad juju, condensation drips on lamps, lamps run too cold.

4. Y'all have done a great job killing AC, but the heat has to leave the room somehow. I suggest water chilling, as it cools and dehumidifies the room air, cools RDWC/hydroponics water AND HEATS YOUR HOUSE FOR FREE with the waste heat. I do it myself, I highly recommend it! At least do yourself a favor and factor in buying dehumidifiers along with any AC you purchase. Suddenly water chillers look a lot more affordable, huh?

5. Why are you using sealed and vented hoods in the first place? To get rid of excess heat, right? What if I told you it didn't work?

That is, what if the cost of using it was higher than the benefit of less heat? Seriously, I've found that the best way to use a glass covered reflector to cool your grow room is to sell it. Use fewer bulbs to grow the same yields, using less space.

Go bare bulb. Less glass to get dirty and impedes both needed spectrum and intensity.

Go vertical. Get three times the canopy space per watt.

If I had your room, I'd run two Tons of water chilling, a big cold water res, and four of my Super Silos, for a total of four hundred square feet of trellis surface. Then I'd look for someone to help me, lol

My tent is 86 degrees. Unfortunately I am unable to use AC. Any additional tips?

Dude I'm using a 10k btu ac it's barley keeping my 1k at 86 degree and I was planning on adding 4 more 1ks so idk eft to do now

Cooling is the hardest part of this shit

I think we will dude specially with winter coming hopefully that helps us.
Iv grown in these temps without any sighns of the plants hurting but I know it's not optimal so I feel like our yield and potency will suffer a little if we don't get it in check.
