10k hps ventilation

Looking into what type of airconditioner i'll need. I'll be running aircooled hoods encased w/ glass with a 425CFM inlines for each individual hoods. Thinking about setting up individual ducting for each inline so that each lights getting cool temps from outside the room.

What do you guys that have burned mulitple 1000s think about the conditioner needed?

I have an 8" fan that pulls air over 2 1000W lights. I'm pulling air from one room over each light then exhausting into the attic. The air cools the lights so much you can put your hand on the reflectors as long as you want without getting burned. I am running 4 lights total and have a 12,000 BTU unit in a 12X10 room I can get the room down to 70 degrees no problem even on the hottest summer days.

I'm guessing that if you have everything vented correctly you could get away with a 24,000 BTU unit.

Hey Boozer are you scrubbing that air before it goes into the attic?

I have heard 3500 BTU per 1000 so 35,000 BTU or a 3 ton unit. If you use air cooled hoods you might get away with alot less.

Buy two 8" Vortex fans. Hook 5 lights up in a series. Attach a CAN Carbon filter too. Exhaust air through attic/home/garage/whatever.

Weed Rooms Open Air --> CAN Filter ---> Vortex Fan ---> 1kw Light --> 1kw Light --> 1kw Light --> 1kw Light --> 1kw Light --> Exhausted to outside room
Weed Rooms Open Air --> CAN Filter ---> Vortex Fan ---> 1kw Light --> 1kw Light --> 1kw Light --> 1kw Light --> 1kw Light --> Exhausted to outside room

Twice for two arrays of these. Use a separate fan/duct to bring in outside air. This way you have all your filtration and exhaust on one easy setup, and the intake on a minimal but super effective setup. You wont need air conditioning most likely unless its really hot outside air. If it is, just flower at night so the fans are off from 8am-8pm, the hottest time of day.

Hope this helps.

Hey ResearchKitty what about "intake air?"

Intake air is easy> Just blow air from outside in. Fan, duct, done.

If you're running 10,000W, I'm assuming cash is not the issue.
Cooling lights and exhausting the room on the same circuit is inefficient at best. Two 8in. Vortex will cool 10 lights without much trouble. Two 10's would be better. Make sure you're hoods have 8in flanges to get the full benefit of the fans. Hood air should never mix with room air. Make sure every joint and crack is thoroughly sealed with aluminum tape.
Exhausting conditioned air is just Nuckin Futz!! Either seal the room and use AC or exhaust air with another 10in fan circuit. Air cooling the lights should remove about 60-70% of the lights' heat, but none of the radiant heat. This is where the AC or exhaust comes in.
Exhausting will require a larger filter than a sealed room, but is definitely the cheaper option.
With a sealed room, a 8in fan sitting on top of the fan over in the corner will keep any smells in check. You'll also need CO2 injection with a sealed room.
All this is based on my own experience, only. You're results may vary. I run two stadium rooms that started out exhausted but eventually went sealed. Sealed is better! Much more consistent atmospheric control.
Hope this helps.

I dont understand this sentence. An 8" fan sitting on top of what kind of fan? Is a carbon filter needed at all in a sealed room?

Sorry, too much rhino for lunch. I meant a fan sitting on top of the filter. It runs 24hr.
