Ok I'm getting ready to build my new grow room I'm bumping up to 6 1000watt hoods 4 plants under each in soil. I have the option to do a 12x12, 12x15 or 12x18 whichever would be best need input on that also. I live in Michigan so summers arent horrible but......Clones will be in dirt 4/1 hopefully harvested by 7/1. I have a 8k btu portable now which I'm not happy with at all my question is I figured I need about 25k btu should I run a 20k btu window unit and a few portables, or just spend the 2k and get 2 18k btu splits or 1 30k btu split also will have 6 wall fans, 6" hoods with 2 inline hurricane fans thru the hoods vented outside on phresh filters. Ballasts will be out of the room also. Thanks for all the input​

I run 6 1000w in my flower room (ballasts in room) with a SoleusAir 14k btu unit sitting in the room also have house unit that runs the room as well (shitty half ton unit lol).

I also have two 25k btu window units in another section, one for killing the heat coming from light duct, other near ducting intake to cool the shit out of the room for super cold intake air.

(flower room door open to show where it is, also second AC unit behind me in picture on right)

Am able to keep my temp around 75-77, but I also live deep in the South, and also have to run at night because of that. I have problems with heat in the summer sometimes (last few have been super hot) and would have a 5 ton unit for the room if I was able to put it on this spot. I also don't run co2 cuz of heat. would be nice If I could get my room colder, but am pretty much stuck until I switch into a new spot.

I would defiantly make sure your happy with the temp b4 u get in full gear, I wish everyday I could do something about the temp but its not worth taking everything down to get work done either. What would be best is to have a regular house unit (2 or 5 ton) dedicated to that room alone. plus at least a window unit (that 8k btu may be enough depending on how big area is to cool since your exhausting out) where your intake is if it is outside of your flower room like mine. exhausting out is a bad idea where i am located.

Yeah we have gotten 110+ summers for the past few years, but being much further north than me, you will have easier effectiveness than me. This last summer with the current setup i showed, i had temperatures spike at 81-82, but also having to run at night. Running during day it is almost impossible to keep my temperature below 85 during the summer. I am debating putting another 14k btu unit inside my flower room like the one I already have for this summer. Running super cold air from and outside intake and also exhausting out of the room helps, but you can only cool those lights so much with ducting. Its going to mainly come from what you are pumping into the room, which is why i suggest getting the big unit if you got the cash to get it done and a trusted A/C man :D

Have you considered splitting your space into 2 separate flowering rooms? If you did this it would give you many benefits. You could also introduce co2 into your grow to allow you to run at higher temps.

If you were to pull your ballast out of your flower room and put them in the outer room with your window unit, it would help your heat a lot. Also throw a 90 on your pinched duct coming off your hood. Plants look great!
I would throw a wall right in between those 3000 watt runs. You would lose alot less light too.

Well I know if i dropped a 5 ton unit outiside my house dedicated to my flower room it would do the job for me, so 2 separate rooms with same amount of lights would be less heat so I would think that would do the job for you just fine.

As for my room yeah I think I am going to wire myself some 240 extensions and pull those ballasts out of the room for next run since summer is coming.

If you were to split your rooms you would only be cooling 3000 watts at a time, compared to 6000. This way you are only looking at about 12000 btu's/room. Also, add some co2 and you could start running about 5 degrees higher than what you are used to no problem. By splitting the rooms, you would also have a smaller foot print to illuminate. Giving your 'rooms' alot more lumens.

For a six light set up about 100 sq/ft would be a good footprint. 10x15 would also give you working room. As for your a/c, I would go with the largest one you can afford. You can buy units now with 2,3 and even 4 heads that can each be controlled seperately by the same condensing unit.

Portables are basically power suckers when you are talking about cooling a room your size.

A N D . . . that's why you split your space. Theres no reason to battle large flower rooms. You end up wasting too much money on unnecessary cooling systems. I run two flower rooms with dual hose portables and hardly ever have to run them simply due to co2 and fresh rocky mountain air.

Same size room with the same amount of bulbs ends up with the same heat issues...even if you split it up. There are no advantages to splitting into 2 rooms due to heat. It also comes down to bulbs...1000 watters are HOT.

What are you running for light if your portables hardly work?

. . . right. if you are working with two separate, 3000 watt spaces . . . it's the same as cooling a 6000 watt room. Keep up the 'great' advice bro. I'm ACTUALLY running two 4,000 watt rooms, so why don't you take the bench there big guy?
