CFL light housing/cool tube effect??

jbreeze · #1 01-07-2008, 06:24 PM

Here the run down..I got a cfl grow goin, true closet grow, 3 plants, bout 2 weeks old, but I am goin to have serious heat issues when all the lights are on(I had 12 on just to test in this decent size closet an temps around the lights were like 88-90 degrees with 2 fans, pushin n pullin air). I only have a couple on now cause thats all the plants seem to need for now but it seems like each bulb jumps the temp up like 2 degrees around the lights. I am thinkin about buildin some sort of housing for the lights over the plants that I can vent the heat out of like a cool tube and then just have my side lighting free to move around..lol that just sounds funny, cool tube for my cfl's haha, but I do have serious heat issues. Anyone come up with something like this I can look at? If not im gonna have to get crafty and let you guys see what I ghetto rig, and Im sure it will be ghetto. I wish I just had a full room to use

hey breeze... i know I have seen HOODS... fabricated hoods that can hold a shit load of CFLs.... and that would be easy to VENT/exhaust... it might get a bit pricey.. to get a hood and a fan + ducting...

cheers

i was having the same issues with CFLs i have a cab that is 16x16x34 34tall and i crammed 11 26w CFLs in there. and i am only using 7 of them now due to heat issues.

i am in the process of building a new cab that is much bigger, then my heat issues should go away.

i would like to see something like a hood though that we could vent. i made one that held 4 sockets and i used the Y splitters in each so it held 8 bulbs and i just used the aluminum sheets they sell at home depot and bent it into a hood. i'm guessing you could do this and somehow mount ends on it then a sheet of plexi over the lights and vent it out. thing would be huge though.

I got somethin im buildin right now. I will have to get a pic up. It actually looks like it will work and wont take up to much space. Hopefully it works. Im messin wit bag seed right now but I got some fem snow white on its way and I want as much light as possible in there for flowering.

Would not 1 250W CFL create less heat than 10 x 25W CFL's ?
My guess is yes.
This may save a few degrees.

yes! the smaller cfls cause alot of heat issuses.

yeah but the prices don't compare... i went for maximum lumens for the money. maybe with fans in the long run they will cost me more.. who knows.

it worked!! my cfl light cooling actually works very well. Dropped my temps about 10-12 degrees! I cant find my dam camera cord or I would post a pic. I basically just used a picture frame, cardboard, duct tape, a cardboard roll(like posters come rolled up in), and a computer fan. If you just had those items in front of you, and you are a little crafty, you would probly be able to make what I did with out even seein mine. I can now have 12 cfl's at 77 temps where I had 4 cfl's at 82 temps..Fuckin beautiful
