c02 and air conditioning *for you pro's out there

[fuzygrowth]

Hey folks.. i'm in the middle of settting up a new room. it will be a large one consisting of 8 600 watt hps lights. I also want to use c02 in the room and have already purchased the green air cd36 which will get my room up to level within about 5 or 6 minutes. the c02 generator combined with the lights will produce alot of heat. which is what brings me to my next challange, figuring out out the air conditioning. The lights will be in cool tubes on 6 inch vortex bringing air in from ouside of the sealed room through the lights and out the other side.

So i am considering buying a 16,000 BTU portable air conditioner, they are about 550 bucks and if it does the trick it'll be worth it. The problem i see and wonder about is how these guys exhaust their hot air. It goes through a duct leading out a window or something simlar. Now it's exhausting the hot air, but it's pulling it from within the grow room, thus removing all of the precious c02 along with it. How do you get around this??? i know it's a winded post for just one question but a little background info is always good don't you think..


Thanks for reading

windo AC units don't mix the hot air they exoust with the air from the room, they draw air from outside heat it while cooling the air from the room and exhaust the same air back outside, so they should not effect the CO2 level in the room

they are not window units, they are portable air conditioners, it has a duct coming out of the back which gets rid of the hot air around the compresser and the hot coils.

I really don't think a 16K will be big enough for 4800w + burner + the room space....is there a reason you're wanting to use a portable instead of a window unit? Dual hose portables won't exhaust room air, but single hose portables will...

Sandman : the more i think about it the more i realize i will probably have to use a window unit. there is no window in the room. But, what I will end up doing is building a 3 foot wide room next to this room, kind of like a hall way, where i can put all electrical and exhaust hot air into, then exhaust that room out through some ducting. This will alow me to have 2 flower rooms, one on each side of the "hall way".

How much cooling power do you feel is needed to cool this down, keep in mind the c02 gen will only run for about 5-6 minutes to get room up to propper ppm levels. And all the 600 watt lights will be contained in 24 inch cool tubes with a 6 or 8 inch vortex (i have one of each) i also have a 4 inch vortex, and also have another 800 cfm squirl cage blower. Thanks for taking the time to discuss this with me at this very critical stage of planning. You can bet this grow will be well documented. Oh yea, speaking of documenting the grow, where is this sever located??? Thanks again

That sounds like a good plan...but I'd try to keep the electrical partitioned off from the heat that the AC will generate. Maybe use the 4" Vortex to supply fresh air to the intake side of the back of the AC and a plenum around the back of the AC connected to the 6" to exhaust the hot air.

Personally I'd go with a 24000btu for most climates. If you live in a very cool climate, an 18K will probably be fine...likewise if you live in a tropical climate, I'd go with a 28K or 32K.

I could be wront but i think i remember someone on here using a portable AC unit that had a hose for intake and one for exhaust... That would work if you could find one of those.

it's true neuronaut , i've seen those on a couple of websites. the more i think about it the more i think that the idea of having a small hallway next to the flower room with a "through wall" air conditioner is a better idea. I have found this frigidair unit which is 25,000 BTU for 400 bucks, which is pretty damn good. i'll just need to wire a 20 amp 220v dedicated circuit to it. there's alot of wiring to be done anyway. Where do you find cheap 220v timer meant for 40 or 50 amps. i hate the word cheap.. lets say "well priced" .

Home Depot...intermatic 40a/240v timers are around $45 there...usually near the water heaters or on the end of the electrical aisle.

I use a 12000 BTU window unit and a 9000 portable in an 8 by 8 room with a cd-6 green air burning for 8 1/2 minutes every half hour and 3 1 K vertizontals,that'll give you an idea you're going to need some btu's.When using co2 and a portable AC,you must use a dual hose and stick the intake hose through the wall to an adjoining room and of course the exhaust up through the ceiling.Use a single hose unit and you will lose your co2,you wont lose it through a window unit at least I dont

will a window unit suck unfiltered odors out of the room?

Just go with a split a/c system if you got the money to burn. You can place the compressor unit anywhere, run your lines inside, silicone the hole and mount the indoor unit up on the wall.
Even though your planning to air cool all those lights they will create some radiated heat from the light itself. Try to locate your ballast outside of the room and save yourself the additional heat in the grow area.

A window unit shouldn't suck the smell out of the room unless you open the fresh air vent that some units have. There are small drainage leaks with window units which is how the condensation makes it from the coil to drain outside.
Good luck.

split system is a bit much at the moment, i hate to skimp but you gotta make it happen too right. nothing is being skimped on this grow.

i've decided to go with the 25,000 BTU frigidair, it's 400 bucks which is doable for me at this point, and it's 25,000 fucken BTUs! lol.. thanks for the advice guys

 

[2buds]

fuz, make sure it has an auto-restart feature should the power blink for a second. You don't want everything but the AC to come back on and cook your hard work bro.
Peace

 

[senseless]

you should also look into a thermostat to kill the lights in case it gets to hot durring an AC failure.

 

[fuzygrowth]

good point senseless, i called the manufacturer of that a/c unit i posted and sure enough, it does not have an auto restart feature. So, now i'm looking again for a unit which is 20-30 k BTU that has an auto restart feature... if any of you guys out there know of a good one that is reasonably priced, feel free to hit me up. Thanks
