Can I Use Cool Tube Exhaust to Exhaust My Room?

[Grower4God]

Would it be possible to, instead of having my cool tube hooked up to an intake from outside, simply hook the exhaust up to my cooltube and let the tube suck air from the rest of the room? I find this really important, because if I can just get a nice 175 CFM fan and hook it up to my 1000W, I could put the carbon filter there, and cool my light & kill my smell in one fell swoop. This would save a lot of money, as well as just make my ductwork conveniently less complicated.

i hope i'm understanding your question right. if the question is can i use one fan to cool my lights and clean the air using a filter, you sure can, here is how my room is set up, temps are perfect and smell is not an issue.

you'll have to excuse the pic, just something i put together on paint.

That's how i;ve done it for the past couple of years. I don't have space or the ability to have any more vents and fans so it's just the one fan and no ducting on the other end of the coolutbe. Only thing to keep an eye on is dirt, the inside of the cooltube and also the bulb can get covered in dust and this and that very rapidly so just give it a good wipe every now and then.

edit damn, hadn't thought about putting it that way around. would remove the dirt issue i experience, although i wonder how it might effect temps in my cab. Might have to have a go.

I get the impression that you were asking whether or not the air sucked through the cooltube must come from outside of the environment (another room, basement, outside, etc).

If that is what you are asking, I think, in general, the answer would be no. Though, it would be another option to consider in tweaking the environment later, if necessary.

Well down the line I would like to buy a second cooltube (my first one I own in my imagination and will be ordering in reality very soon) and hook up the cooltubes in a line with each other. At that point, it would be wise to bring in a line from outside (at least during winter) as it may get a little hot, and at the very worst the intake would help extend the bulb life of my lamps.

Thanks so much ghb, and you are humble; I was flattered that you painted me such a pretty picture! I now move on newly educated. HOWEVER, I'm kind of tripped out by the fact that you're fan blows IN to your light... Traditionally the fan follows the cooltube, since air can pull easier than it can push, no? Do you need a particularly strong fan to accomplish this? OH, or do you use duct boosters along the way?

I was thinking to get a 170CFM off HTG, on which I read that for a space my size the necessary level would be about 120CFM, so I guess I wouldn't have much of a problem.

ANYWAY... underly medicated and overly excited, I digress. Thanks so much for all your help.

The only question I would have is is 175cfm enough to pull through the filter and cool the tube.

i run it this way to keep the fan as cool as possible because it is on 24/7. it is a 6" rvk with the upgraded motor so it is real powerful, therefore it moves the air through the tubes effectively. having the fan after the filter but before the bulbs also helps stop the bulbs getting as dirty ( a lot of carbon dust comes out of my 24" filter). i run it that way because i think that is the best way for me, ideally you would have one fan for the cool tubes and one for the filter.

just a Q.how are you getting oxygen in that sealed grow area?

I doubt it's a sealed area.

 

[ghb]

its a tent, sealed room with co2 is for the future lol.

yep, I run this way. Sucking air is sucking air, with two caveats. The CFM will be reduced by the light, so if you are looking for very specific CFM's in turnover, you will need to accommodate for the extra ducting. Also the cooler the air going into your light, the better it will be cooled. If your rooms ambient temps are high it will reduce how effective the light cooling is. Keep in mind though that if your room is hotter than your light then your plants are dead, so it's unlikely it would ever just not work, and you might not notice the decrease in efficiency if the ambient room temps aren't high.

It will work fine doing it that way. the only problem you run into is when it comes time to move your light, so take that into account.
