questions on cooling room with all adjust a wings

[spaceboy]

hi everyone

I just got rid of my air cooled in hoods in favor of some 3 medium adjust a wings with 600's and my temps have spiked up to 85 degrees. The room is 13x7x7 and right now I have one can fan 737 cfm connected to a filter for my exaust and just got a 400cfm inline fan for an active intake to try and cool it.

I'm not noticing much a difference since adding the intake fan. So my last idea would to use the intake to pull cold air from outside and possibly rig it to some type of thermostat to control it. I really dont have the money for ac right now and actually have 2 more of these wings to put into the room if I can figure out this heat.

The weather is breaking, so it might very well work itself out within the next several weeks... Like tomorrow it will drop back down in the 40's.

But I hadn't found much use for an intake fan and like to use passive... Let's you control air pressure better.

You could rig two outs with both fans (pref w scrubbers) and run tubing for passive intakes drawing from the cooler air, but you'd also be drawing in the moisture, and it rather wet out there.

Really an ac is the best route, but the weather is breaking...

I don't understand this part. It should be your first idea to pull cold air from outside. Where are you pulling it from now?

You don't really need an intake fan, like MIway said. Just push air out with your fan, and put that on a thermostat.

get a bigger intake fan. and passive intake blows chunks unless its a small gro. IMHO

Its taken all day for it to get up to 82 in there, which normally it would be 85 after a few hours. Its not much, but its a start I guess.

Right now I'm sucking the air from another room in my basement, so its fairly cool air. I havent pulled from outside because of the moisture and also wasnt sure how that cool of air would affect them.

If I do decide to pull from outside are their any precautions I should take to account for the cool temps or extra moisture?

I would pull passively from the basement while at the same time hooking the intake fan on a thermostat to dump in colder outside air as temp demands.

Or perhaps pull passively from a lung room which can be brought down in temperature via the temp controlled outside intake. This would allow you to dehumidify as well as filter the passive intake before entering the room.

Open hoods require a lot of cool air. Without being able to draw dry air from outside... you're really stuck with A/C.

Did you already dump your air-cooled hoods?

Stay Safe!

Thermostat on the fan and possibly get a dehumidifier.

I'd recommend insulated ducting.

You'll likely experience condensation issues if not as cold air travels through your ducting in a warm room/basement. Insulated ducting should sort this. The shortest run as possible also. I've found that even pulling 30 degree air from outside.. given the length of duct it has to travel it could be much warmer by the time it reaches your room or intake. Mine was already 65 by the time it entered my room.


I'm in the process of doing the same. Buddy is going with 3600w in adjust a wings..3 600w in each 5x10 tent. We've never ran un-cooled lights in tents, but planning on exhausting each tent with a 6" Vortex to an un-used upstairs bedroom. Intake will just draw from the basement...with an outside intake bringing basement temp down on a thermostat. Hope it works..

Keep us posted on your situation.
