Help!!! Need to cool a 600w hps in a cupboard asap!!!! +rep!!!

Hey what up man. Look here i have a 6oo watt vegging in a 3x4x6 cabinet and my temps go around 79-82 degrees. First off i dont know why no one has said anything, but you need to move your fan. Those kind of fans work better "PULLING " air instead of pushing it. thats how they are made. If you wanna check my thread, its like the second or third post with a pick of my cab (btw i now have the ducting open on the inside, sucking all of the hot air from the inside on top of the light, and blowing the heat out of the cab). Im sure your fan is of the 400 and up cfm"s. Well i have a 265cfm dayton blower, but i have it pulling air. And its located on the outside of the cab. So basically i now have the ducting open on the inside, sucking all of the hot air from the inside, and from the top of the light, and blowing the heat out of the cab.hope that helps bro.


Peace!!!

I used one of these fan with my first grow. Works AWESOME!! but it's kinda loud lol

Ok so a few alterations here and there but I am getting there 6" intake, 90oC elbows re-configuring the in-line fan and a fist full of other mods and this is it so far - STELTHY

I thought the extractor is meant to suck the hot air from the cooltube not blow it out. Could be wrong though as it's just what I've seen.

Oh you already know, woops.

Pull air whenever you can instead of pushing it.

If you can setup the fan to suck through the filter it will work much better.

If it's just a summer issue i put frozen 2litre bottles of water in front and behind of my intake fan to help blow cool air around the cupboard,
you'll have to change them a couple times during the day but it helped me reduce my temps by 7 degrees.

Seems like a lot of work...

This is what I installed to cool the 3 ballasts 250w, 400w, and 600w respectively and wired them to a multi out transformer I will have 3 0n the front too to pull the air through... Job done - STELTHY

I check my flower cupboard daily so it's only a lil extra hassle,
plus i only get extreme temps for a few weeks a year so it's really no big deal
