Need Help with Heat & Building Setup

Okay Guys, We have a heat issue that we have been trying to deal with for some time now and no matter what we are still sitting too high in temps. So its time for your opinion or advice on how this should be.

VEG A has no issues with heat.
FLOWER A gets 90+ Degrees
VEG B gets 90+ Degrees
FLOWER B gets 90+ Degrees

Last time I was around, they added a swamp cooler by the door of Flower B that got the temp down to mid 80's. But it ended up breaking so I didnt include it in the diagram. I believe but im not 100% sure, they have recently walled off VEG B from the storage/front room and a portable a/c has been added to that wall. So I believe VEG B may be okay now. It was open with no door or wall by the stairs shown in the diagram.

When you walk upstairs, its like a loft over looking the storage room but is walled going any further back if that makes any sense. Flower A & B are exhausted upstairs, and there is a fan upstairs that sucks hot air out the roof but its not doing to well at that. The vents from the two rooms just sit up through the floor. They dont connect to anything upstairs.

They went in yesterday and found the swamp cooler broken and temps over 120+

You can only imagine how the crop is doing. So this is very serious as there is a lot we have lost and will continue to loose till we get this figured out.


Anyone have a better idea of what we should be doing differently or how to get temps down? Money is no issue.

Thank You!kiss-ass

How many fans do you have pulling air out of those lights? Getting some more 6" 400+ cfm fans should help pull away more of that heat, as well as replacing the fan upstairs so it can move more air out of the roof.

And they are cooltube/sealed lights correct?

You guys should think about getting a dedicated a/c to cool your hoods. like this one: http://www.growlightexpress.com/ind...ct_info&products_id=1261&cPath=101#googlebase

Or one to suit your needs. Then connect the ducts directly into the ducts on your air cooled hoods.

I would set it up in the upstairs loft and connect 2 ducts coming off the a/c into 2 of the ducts used for exhaust. Re route your fans to go with that and that should help.

22 1000w's damn i'd say you heat issues. How much power does that suck? I was going to say a/c setups and ultrasonic humidifier or evaporative cooler but idk if that will help or not. Sounds like you need to pump that heat outside.

I actually think my diagram is an understatement. I think there is 4 More in Flower B.

Well currently each room has an 8in Can Fan "SUCKING" air out of the lights. All of the lights are sealed.

Flower A has roughly 6 1k Lights, Daisy chained as shown with 8in Insulated Ducting between each, going out to 1 8in Can Fan that blows the air upstairs.
Flower B has "I Believe" 6 1K Lights in a row, Daisy chained as shown... ^ Same as above but there is 4 rows. So Flower B has 4 8in CanFans, 1 for each row. Sucking hot air out.

The reason I say believe or think is mainly im not in it 100%. It was a group of people close to me who ran this. One is now gone for awhile, another took over, and the rest of the people have now stopped doing shit and are no longer helping. So im trying to help the best I can because it irritates me that these people arent stepping up to help.

So ive been helping for the past couple months now. The person running it is a clueless female. Not to be putting females down, but her husband made a bad choice and is now gone for awhile, so she took over and ever since people have stopped helping and things have gone down hill.

We were seeing buds the size of a normal male's forearm, that was easily over 6in around. Went from top shelf amazing stuff, to dirt within 2 months due to the lack of maintenance and proper cooling.

So what Im getting here is stop sucking the hot air, but instead have a dedicated AC Unit to blow cold air through the lights?

Currently in each flower room is a 10,000-12,000 BTU Window Unit at the back of the building. Which sucking the air from the lights, its sucking also ambient room temperature. So with what we were doing, we were trying to cool the room itself, and let the heat from the lights just suck away. Not letting it go back into the room. But with how we were doing it, it still was way too hot.

Just get more fans. More 8 inch can fans will help. If you dont want to use the AC listed above water cooling them could be an option. heres a few systems and coolers. Youd be able to put the coolers in the loft and it would minimize heat then you could just circulate that air around the room?

The window units take out about 1/3 of the air they make to cool themselves down so i dont like using them for growing because it can let out unfiltered air that smells.
