I have 6x1ks and havent got them all running yet but have them with aircooled hoods on a closed loop.How hot will it be once all 6 run?
Im going to pull fresh air in from 2 areas and have a 12" exaust if it gets to warm,but i want to run co2 and am tring to fuigure out if i need to get a air conditioner....any recomendations?

I'd love to help, photos? what size grow room/s? (dimensions) And what temps are you getting? If warmer than 27 Celsius (82 degrees) than co2 is vital. You can get away without co2 if you get an ac unit set at minimally 26.6 Celsius (APRX. 80 degrees usa)

im curious too !!

Dude, there's NO WAY to run that many 1000's in one room without AC...IMHO. Figuring out how to deal with cooling the room separately from the lights, and with Co2, while factoring in how to deal with odor, is quite a chore. Are you sure you want to run that much? How many grows with 1000's and Co2 have you done before? Not trying to sound harsh, the only reason I ask is because I'd hate to see you invest so much in all this equipment, only to end up frying those plants up later on.

IMO, you're going to have to cool those 1000's effectively first and foremost. Even with air cooled lights, it will probably still get hot in there. I just don't see any way around getting an AC unit. I'm looking into one myself. In fact, I posted a thread about it in the Grow Room Design and Setup section. In order to help you though, I need to know if there's a window in the room that you can use a AC unit in. With as many lights as you're running, no portable AC unit will be able to handle the task. (Again, my opinion) If others have or are able to make a setup like that work without AC, more power to them. All I know is, I've never seen a grow with that many 1000's not running it.

6000 watts will put so much heat into any room no amount of air cooling alone will take care of it. As previous posters have mentioned you have to control the heat to have an effective grow with that much wattage. In my opion from banging my head against a wall, I found out that trying to run a wall unit in one room by itself doesn't work to well cause you have a centralized high level of air coming out that isn't spread around well and you have to work that unit to hard to keep the area coverd you have with the 6000 watts.



You would do better by looking into liquid cooled options at that level. You could go with the ice box if noise isn't an issue for you. You would pref. need a good chiller setup and a fan on each light. Then you get cool lights with cool air in the room as well!!

Or you could go with a custom a/c configuration in one room with liquid lumens if noise is an issue for you then you just need a sealed room with regular exhaust and intake and the custom air.

No matter what you decide you will need an air conditioner. Hope this helps

yes m8ty most def got to get air con with that lot phew can feel the heat from here lol

Thanks for stopping by guys!

The room is 13 x 11 with a window where i have built a window box 12"out 8"in
I was going to run a closed/sealed room but couldnt get the 1 to 3 grnd for the 24,ooo btu split ac.So my plan was to pull air out with the 12" fan
Intake for ac lights would be a hole cut in the wall through lights with {from cooler room} and the fresh aair comming in a hole on the door to that room.

I was originally going to attempt to void cutting any holes,but sheet rock looks easy enough to repair.
By my calculations i need about 24k btu to cool 6 x 1ks.
But those are a bit too much $$ for now,i though about using my homedepot card and buying one,but i couldnt find the prices for their trane ac systems.

I have the lights hanging in 2 x 1k pairs {3 rows}covering roughly an 8x4
{would a 9,ooo-12k btu ac help 6 x 1k a/c lights on closed loop?}

the ice box liquid cooled fans look nice too but their chiller is $$$$
I am on a budget so cheap or used or avail at home de pot.
I could spend 6oo bux tops cash {if i dont get a co2 controller},but rather spend less.
Any ideas/pictures of sealed,CGE,CEA rooms,or rooms with a/c lights using co2 would be rewarded with thanks and praise!
Recap of room specs:
11x13
1 window
1 door i can cut hole in {or walls}
6 x 1ooo w ballasts in room =(
resivoir is in room =(
ouside air is 8o - 85 f usually

Thanks again for any interest in helping me

You ever noticed that there are so many that say you can't do that! You'll never be able to do that, that will never work. Well most of those people have never done it. First off you have the right size exhaust. You can pull air across 3-1k's on one run and 3-1k"s on another to the exhaust. just don't daisy chain them. What is the room in, a basement? If so a great way to cool the room is to cut 2-6" holes close to the floor,(same wall). Utilize the a/c from the rest of the basement. Your pulling in conditioned fresh air from a larger volume. A/c will work less. Air cooled lights still put out a great deal of radiant heat, but that can be dealt with by air circulation captured by room exhaust. Put your room exhaust on a timer that goes off 15 min after the lamps go off. and then come on a few time during the dark period. The room exhaust can be attached to a carbon filter. If your dead set on C02, your going to need a greenhouse controller, kinda pricey, but work it to avoid the headaches. I was reading your post, you said a closed loop? Have them T off to a filter?

Very true indeed,My friend was running 1o x 1k in a/c hoods {closed} and ran ac and kept it cool while running co2,he had great temps.

My room is just a bedroom,so could cut 2 x 6" or 8" holes in wall,drawin cooler air from the hallway,would this work? I can also cut a hole in the door down low for extra air.
Would a window ac work? A friend has this forsale for 15oo,how would this do?

Im a liitle confused on the "t" on the filter,i have a 12"to double 8" Y that i could use.
Should i configure lights in 2 x rows of 3 lights or 3 rows of 2 lights?

Much thanks for you help!

I would never post on any topic that I did not have direct involvment with or understand completley what is at hand when given questions regarding why I have posted about something.

Why I did not give suggestions on the normal way you "air cool" a room, notice I didn't say "air condition" a room, is that with that many lights and doing it the way he is suggesting, will you grow something? Yes, its a weed it's very hard to kill it once its going, but you won't have anything worth anything. I would assume since you are using 6000k watts you are not growing it all for yourself so I don't think the other people you are growing it for will want what would come out of a room like that.

My suggestion would be to use less lights untill you can afford to set your room up properly and get good return instead of crap! It is allways going to be a building process untill you stop growing thats just the way it seems to work hope this helps
