OK so i knew it was a little crazy but i bought a grow tent 36"x20"x64", and got a crazy deal on a 1000 hps with a coolable hood. so i installed the thing to the very top of the tent(which i got to fit in my closet). Turned it on and in 30 minutes it was 120 degrees. So i went and got a 6" inline fan and put it to suck air through the hood and out the top of the tent... still 110 degrees. I just put a cool mist humidifier in there on low. but my question is will a humidifier crack the bulb? I live in a dry climate so i figured i would need one anyway. anyone have any comments or ideas? I will post pics as soon as i get the rest of the work done.

Ok. so I added a fan to push air up to the intake of the exhuast. Still up to 100 degrees. Then i opened up one of the closet doors and temps dropped to just under 90. Thats good enough for now. I took a couple pics of my setup. Anyone with suggestions?

i have a 600W cooltube, in a closet. the only thing I could do to bring the temps down was to buy a portable a/c.

you could also get some ducting, and suck air from a cooler part of the room. that will bring cooler air over the bulb.

also what size fan are you using? cfm?

Thanks for the reply.. U play bass?

Im using a 6" Inline 250 cfm. might just end up sticking clones in there and leaving the doors open for now. 7a-7p flower.
Started a seed few days ago. One mystery bagseed(supposed to be of decent quality). Sprouted today so im gonna use some cfls for a couple weeks, then ill turn on the sun!!

you think it would be better if i suck air from a cooler part of the room, straight thru the hood and out, Or just suck cooler air into the tent and let it go up to the hood and get sucked out?

the closet isnt hot bro.. the light is... bring the cool air from the room, across the bulb, and out of the room... try to exhaust the heat from the bulb into another room altogether...

youre gonna need a bigger fan. I have a 450cfm cooling my 600. that would help your temps drop.

yeah i play.. the one in my pic is my musicman stingray, i also have a fender jazz marcus miller edition...

Cheap fix.... Get a portable ac unit like said earlier. Check my grow journal I use a 400watt in a tent 4FTx4FTx6.5FT. Going for 12 plants, mostly all 'fucking incredible' and 'white widow max' strains. The temps are perfect(72 at "night"(going 18/6) and 81 is the hottest i've ever recoreded, and thats on a miserable hot day), the electric bill is hardly noticeable. Maybe consider sizing the light to at least a 600. I've seen excellent results with 250HPS. In that little space a 1000watt is insane and you'll NEVER get ideal temps, not without a portable ac unit that will also use minimally 600 watts of energy. And then with your 6"inline fan has got to be at least 100 watts (1700 watts!!! OUCHH)...a bit sketchy for an apartment, for that is where I grow.

i have to agree but in your situation i would leave one of the vents on the hood with nothing on it and have the fan sucking on the other side and then blow it out a window or through the roof in to the attic or something, if your only venting from the tent to the room then the hot air is just getting sucked right back through the whole set up causing the sky high temps, your 250 cfm fan is plents to cool the 1000, its what you do with the hot air thats fucking you right now, with any temp above mid 80's your going to need co2 to make them grow but shit, once you get the light vented right temps wont be an issue and you will be putting down some fire in that tent, those plants will grow some nugs that are tighter than a 12 year old

I don't care what you say, with that closet door closed, and a 1000 watt light on, NO FUCKING WAY will you get cooler than mid 80s. I bet upper 90s even the way fat sam says to do, maybe he didn't read how small your space actually is. Good thoughts, but in that small of a area there's no way, I'll bet my life on it!!!!! But if you live in an apartment, it would be crazy to run ducting through the walls, and exhaust to outdoors, if you have an attic even that would be nuts cutting holes in roofs and shit. fuck that. get a new light. or bigger space.

Also, make sure that ballast remains outside the tent. You can easily start a fire if you keep it all closed up in the closet, and the heat from the ballast won't help your situation either. Sell that 1000watt light on ebay, and buy a digital 400 watt, or 600 watt... 1000 watt light performs best in open well ventilated areas, such as a grow room, not closet... Don't burn your apartment complex down dude.

Yeah. I have decided to get the 1000 watt out. Im going to buy a 400w mh and put it in my closet. I found a large crawlspace to put the 1000. Im thinking of setting up a stadium style free flow system. in there and use the closet to grow moms. I just ordered Mazar kush from attitude seed bank. i get a free auto quicksilver seed as well.

For now ill just use the 6 or so cfls i have laying around and get this mystery seedling going. more pics soon.

Anyone try attitude seedbank? What about mazar kush or auto quicksilver

wow i couldnt imagine having a 1000w in my cab. its 3x3x7.5' I use 600w, cool tube. Had to also continuously exaust the room to get lower temps. But im using a sealed room so i got a closed loop ac that mounts to the side of the cabinet and dosent exchange any air. The 1000w is overkill. the money you save using the 600 will pay for itself int he decreased energy to run the light and cool the room. I know you got the 1000 cheap but in the long run it will be alot more expensive when you will most likely get the samr esults with a lower wattage.
