I have this wooden cabinet with two swing doors, perfect for a little stealt grow. I Already have this 150 watt hps security light so why not use it for the cabinet? At least i hope it would work. I read up on cool tubs and have bought all the supplies needed. So with a cool tube can i have a small wooden cabinet (4'h 2'w1'd) cooled down to where a fire would be imposible? i could imagine so but i just want some reasurance. I also have this mother fucking powerful little 4 inch fan Thermaly protected 31 amp fan. But the one thing i worry about is the fan shutting down while im out you know, but i dont think i should worry to much. What do you think?
This sounds like its fool proof as long has my fan is quality and its gowing and working, that box will never get hot enough to start fire?

ok so it sounds good huh? just for a better picture what are the l w h dimensions? yeah all depends huh, so i guess im good, no one seems to think that there should be any probs so onwards i go.
 
ok so i was thinking of a way to make the cabinet as fire resistant as possible. What if i line the inside with sheet metal, which would take all the heat and distribute it throughout the metal while the wood would only get slightly warm. would it be possible then, if my fan failed, to start a fire?
 
Im pretty sure most fires in grow rooms start from faulty wiring or a short in a wire. Or overloading outlets and things like that. A 150 watt hps isnt going to get hot enough to burn wood. It will put off a lot of heat but you should be more worried about keeping the temp down in cabinet for the plants. Just have intake/exhaust fans and a fan blowing in the cabinet and everything should be fine..

If the cool tube failed, there could very well be a fire, that light gets fucking hot, enough to worry about. And yeah i will have a couple intakes and a strong outake that will cool the cabinet so good point, ill just have to have some stronger intake outake fans to keep the inside cool if the fan fails. Whats a good fan that will have a strong airflow for small spaces like this caninet. I heard small blower fans work very good... Anyone know of a cheap, yet powerful exaust fan for this set up??

wouldnt that create an oven in there?

It could become one easy, but im going to create a cool tube for my fixture with intake and exaust fans as well. Im not completly sure on what kind of fans for in outake, but for intake im thinking two of those large 120mm computer fans (thermalcat, the silent ones) and a blower fan for the exaust.
And i have this reall powerful fan for the cool tube, its a heavy duty vent fan of some kind.
 
hook your light up to the same breaker as the cool tube fan. if the breaker goes the fan and light shut off.Buy a good 4" inline fan. bathroom fans burn out. so you dont worry about the fan going dead.
 
yeah good idea, it would have been set up like that anyway. actually my main concern is the fan itself. Im worried that a wire could burn up or the inside could fail. I dont know the possibilities of it happening but it still wories me. Im going to line the box with sheet metal for a backup reserve,

and anyone have any good ideas on a cheap powerful exaust fan that would be relatively quiet??
 
check at HD or lowes they have nice powerful inline fans for cheap, but they might not be quiet, if u got cash get a can fan. i love mine its so reliable and is super quiet. i dont think u will have to worry about a fire if all your wiring is correct. if the fan shuts down all u gotta worry about is the room getting too hot. make sure that nothing in the cooltube is flammable and that it is at least 10 inches a foot preferably from the ceiling. if you have correct ventilation in the room u wouldnt even really need to vent the light, but we all know theres nothing like vented lights lol. sheet metal might be bad cause cause it could retain alot of heat. but if u feel u need to hook it up. also i wouldnt put an intake fan in that is smaller than your exhaust, you want your intake to be larger than your exhaust. a small pc fan could restrict flow from the big ehaust fan, potentially causing a burnout...... i personally would just use an exhaust fan and have passive intake. if air is being blown out air will naturally flow into the area.

I might check out a hardware store. i know what your talking about and i was thinking of one of those fans but there mighty loud. but you say yours is super quiet,,,what do you have bro? it cant hurt for the knowledge because stealthness is something i have to consider considering im growing on the down low and actually im going smaller on the cabinet, i need somethin i can hide in my closet better, so i have this cabinet thats like 3h 22''w19''d. so alittle smaller wich might be why im feeling concerned. and yeah i feel ill need the sheet metal.

Yes the exaust will naturally suck in air but wouldnt two large computer fans (120mm) speed the process?
 
One way to keep things quite it to oversize the fan, but reduce the power.

You can pick up a speed control (for ceiling fans) at a hardware store.

Running a motor at 75% power can cut the noise by 100-200%


BTW - I've got 2 150w HPS lamps in my grow...

thats what im doing with my cool tube fan, its insanely loud, but insanely powerful. i never used one or heard what kind of diff it makes but 100-200% sounds very good, i think im just going to buy some kind of exaust fan from lowes and do it like this. im still going to check out that can fan though.
