Help Cooling A Closet

I got my inline fan to vent the light, i just need to install an intake to complete the environmental control. I need to bring more air into my closet without sucking in the hot, stagnant air that i just vented out of my closet. I am thinking about putting it in the wall on the side of the door, to the right if your looking into the room. This is the polar opposite end of where the inline fan is sucking in but next to the wall where the hot air is being vented. Will the hot air rise enough to allow cold air to flow in from the breezeway under my room or should i try to find a way to punch through the wall and suck it in from the adjacent room?
here are some pics so you can better visualize my delimma.

it looks to me like you are trying to BLOW air on the light to cool it


it takes alot to do that...

while exhaust the air/pulling it will do a better job

so as opposed to blowing air over the light, and away, pull the air away from the light before it can affect anything?

to cool a place


its always better to exhaust the hot air than you try and cool the place down by blowing air in...


hot air has to go somewhere bro

the inline fan is connected to a silver star air cooled hood. All of the hot air is blown out of the room and into the crawlspace in between the walls.

have a large intake fan than exhaust and get an oscillating fan blowing around in there

Okay take off your fan from the left side there...then connect some ducting to the right side...atleast 2 feet or so..then have the fan connect to that with the sucking side toward the light..then attatch ducting to the other side of the fan to the wall going to the crawl space or whatever ya have there...

so it should go light--ducting--fan--ducting to wall...attatching it right on the hood like that is a bad idea...if you do it like this it should have no problem keeping all that hot air out

and yeah have an oscillating blowing air over the top of the plants to keep it cooler...can have light closer to plants too

what.It seems to me your fan is cooling your light, and the air is going into the wall and eventaully in the attic. the air from that fan should be enough to pull air from under your door and keep the room cool. if not just ad an oscillating fan. that 449 cfm kicks ass. and wheres your carbon filter. putt an exuast fan in your ceiling and shove the carbon filter in the attic above your closet. run vent hose from exuast fan too carb filter no smell! and it will help vent some of that heat too.

no you need to get a filter...you can get em at hydro stores...it's just like a white pretty thick but fluffy type of fabric.. that come in squares, get like 10x10inch one and then a clamp that fits the diameter of the open side and clamp it around...i'll try to get you a pic of mine tomorrow but it prevents particles from going in your hood and getting on your light (although it's not really THAT dangerous...my first grow i had no filter the entire grow and it was fine...i needed to clean my glass that goes on the hood but the bulb was fine) not to say i'd recommend it

sorry I don't know the name of the fabric and stuff but I think if you have a hydro shop near you you'll be fine

im thinking about using a odorsoc, maybe i could attach that to the other end of my hood and it would serve a dual purpose of keeping the hood clean and filtering smell?

I don't know what an odorsoc is but I don't think it will help with smell...i mean think about it...the purpose of the filter is to a) keep shit out of your light and b) reduce the amount of air being sucked through so its not like a suction cup in your area...the smell is coming from the plants...not the light..sucking the hot air from the light isn't going to kill the smell...just get some ONA

Texas Hydroponics :: Environmental Control :: Odor Control :: PHAT "Odor Sok" (ALL SIZES)

the odor sok would go on the end of Texas Hydroponics :: Grow Lighting :: HID Reflectors :: Silver Star 6" Reflector
this reflector. The end that it would be attached to would be opposite the exhaust fan attached to the other side.



Update: I switched my fan around like i have been advised, and raised up the exhaust hole to cut down the reduction of efficiency I'm getting from my fan. Now it is a direct blow into the wall.

so now my set-up looks like this .







and then I think i am going to use the duct booster fan as intake for right now, making the room look like this.

It'd be great if you could put another length of duct on the opposite side of the light fixture, and connect it to air from outside of the room. This way, if your light fixture is completely enclosed, say with a piece of tempered glass between the light and the plant, you wouldn't be trying to cool the light with the hot air from inside the room.

A second fan would go in the attic. You could suck hot air thru it and into some kind of carbon filter. The odorsok would be fine.

This way your light would be on a closed circuit, and the only heat coming into the room would be the radiant heat from the light. The radiant heat generated by your light would then be exhausted along with the odor thru the second fan into your scrubber. I think this would be the most efficient setup, with the downside being the added expense of the additional equipment and installation.

what kind of fan should i use to vent in the attic? i have a shelf in there that would be perfect for a squirrel cage blower.
