Help!!! Heat Problem!!!

[joesmiley210]

Any and ALL ideas are welcome. I'm currently constructing a 2'x2'x4' closet grow. I'm using a 4" duct fan (80 cfm) for my air exhaust, and a 14" tower fan to circulate air within the closet. I have all 4 walls completely covered in black/white poly paper (85% reflective). My lighting is 18-40W CFL (6000K) totaling 47,700 Lumen.

Before I started my grow I wanted to test the room fully equipped with my hygrometer. The results: 102 F and 18% humidity!!!

Please if you have any SERIOUS suggestions feel free to give them.

Impatiently being patient...

Ditch the duct fan and get one of these. They are quite too!

Make sure you run the duct outside of the room or else the intake will suck the hot air back in.

Good luck. What strain do you plan on growing?

I love cooltubes...

I keep my 600 HPS 10 inches from my plants in a 36 x 20 x 60 tent... and the temp is around 75F...

Ya but you cannot cool tube CFLs. So unless you plan on ditching the CFL set up and getting a HID set up that will not work. I have seen custom made air cooled hoods for CFLs though. I use to just use a fan blowing on the CFLs at all times and that kept my room significantly lower in temp just by keeping the lights so much cooler. Other than that you need ventilation to get rid of that heat.

Well, you *COULD* cooltube the CFLs, but it'd be more like a small shallow box around all the CFLs and venting instead of a tube, so maybe a coolbox.

Anyways, yea those temps are a little out there. I made a plastic tubing to go from my AC vent to my grow room to help with cooling. Maybe you could do somethign similar?

nice set-up. After exhausting all my varibles in this experiment I've decided to relocate my project. It's funny that you put this picture up too, because my new area looks kind of like this. I built it using pvc tubes for the frame and then cover it using blk/wht poly paper. I will put up some pics later today when I get home from work.

Why would you say something like that?

Have you ever had a cool tube...?

Sorry Bro, you can put just about any kind of light inside of a glass tube that is big enough to fit it in... including CFLs

Please do not spread bad info....

I have seen custom made air cooled hoods for CFLs though.

Uh....I thought you said you can't do it... I am confused....

Are you saying it is possible in a hood but not a tube??? why?

I use to just use a fan blowing on the CFLs at all times and that kept my room significantly lower in temp just by keeping the lights so much cooler.

If you have a fan blowing on your light inside of a closed space, you are still heating up that space...

Other than that you need ventilation to get rid of that heat.

Ah ! I agree with this one... ventilation gets rid of heat....

Sorry if I sounded like a prick, but you are steering the dude away from one of the most effective solutions to a heat problem... a cooltube...

anyways...


Cheers..

Yeah you could... but why not a tube?

Very nice... I feed my cooltube fresh winter air from outside...

Looking FWD to it Mate...

Hey Gypsy i was going to put a fan inside of my growbox to blow on my 150 watt HPS.

Will this really increase the temp inside? How?

 

[KaliKitsune]

Why not a tube? let's see, just how do YOU propose TUBING 18 CFL bulbs? Gonna do all that custom wiring? Plus, with the liklihood of the configuration of 18 CFLs being probably all above like a huge panel light, just for venting efficency it'd be easier to box that off and give it ducting instead of trying to make a tube large enough to encompass all those bulbs.

In other words - simple engineering says tubes in this design are not effective. You could do just as well inverting a shallow fish tank, porting it for airflow, and putting that directly over the CFL mass. It'd probably be a bit more cost-effective, too.

God i hate ignorant people. Gypsy you are retarded.

Ok Gypsy so how do you suppose to fit 18 CFLS in this cool tube? Ugh you fucking cant.

doesnt even have to be that cool tube BUT ANY COOL TUBE?!?!?!? Kalikitsune said it exactly right.

And like i said, you can make a CUSTOM DIY AIR COOLED HOOD for the CFLS. The same thing as a cool tube so stfu.

Dont know what else to say about the fan on the CFLS, i did that and it worked great.... so therefore it worked.

I did not say that adding a fan will increase temps...

I did say that if you have no exhaust or intake, any heat in the box will stay in box... and that a circulating fan would only circulate the heat...

is that better?

I see...

I agree with what you said 100%, but I imagined the higher wattage bulbs I see people using...

If you are using 18 CFLs, a box is the way to go... and I give you +rep for the aquarium idea.. freaking brilliant....

But if you are running that much power.. why not just stick a HPS in the cool tube...?

my 2 cents...

Oh I had noticed your post...

I apologize ...

I will remove my ignorant retarded self from this post...

I am sorry for wasting your time...

Best of luck...

Well, the guy who started this thread is using 720w of CFL. Only at 47K lumens, though. I'm using 432w of T5HO and getting 40K flat.

As for why the guy's not using a 600w MH or HPS, I dunno, either. That plus a cooltube would be tossing off about double the light at about 5/6 the power usage. and would be a hell of a lot easier to keep cool.

Thanks for the new signature...lol...

You are a very rude person by the way... you can disagree with me, even prove me wrong... while maintaining respect all along...

Respect will never hurt you...

But it is apparent that you don't care about such things...

Be Well...

Lol all that? Thanks for the sig. Glad to see it hit the point.

I have 12 lights above, and 6 lights along the side and under neath the canopy. I decided to use the CFLs instead of a HID system just to see what all the excitement is about using CFLs. It's more of an experiment than anything else. I've always grown outside without any unneeded disturbances because of my location.

Thanks to all for your opinions, and insight. I will be putting up some pics and more info in my new journal. Once everything is set-up I will make sure to drop by and leave a link.

Yeah.. I hear ya...

I am running a 600 HPS in a 36"x20"x60" tent.... at 95 000 lumens... I am getting about 19 000 lumens/sq ft...

With the light 10" from my plants, the temp is around 75F... and since I am feeding the cool tube with cold air... the light's exhaust right now sits at 60F (that is after going through the light)...

So I am currently using that (170 CFM light exhaust) as my intake blower... which will match nicely with the 265 CFM exhaust...

Cheers...
