Temps are too high! need help

xstation420 · Jul 30, 2010

i have cabinet grow in my closet. I'm running a 400w mh. the space is 30 sqr ft, and temps are at a steady 90F. I have a fan blowing fresh air into the cabinet and a small fan pulling exhaust air through my hood and out the top of the cabinet. I want to get a exhuast blower but i dont know where to look for a small one and i dont necessarily know what to look for. any help would be appreciated.

this is the exhaust hose

this blows fresh air into the cabinet

this is a fan i have blowing over the plants

what is the temp of the air you are pulling into your cabinet? mine was around the same in my closet when i was using a single 4" fan, i ended up buying a tent and a 6" vortex, you can see a link to my grow in my sig... i think my main issue before was i was using a passive intake, and it wasnt enough to cool my 600w... in order for my temps to be stable my intake air has to be within range, i keep it 75 in the room, it stays 75 in the tent... im also using my 4" now to intake air, then im pushing air through my hood and out the window... also, where are you exhausting at, you need to get that out of whatever room you are pulling your intake from, it will make keeping it cool easier on you... also, if you would like more assistance from me, please shoot me a PM, or give me a shout in IRC... im about to go to sleep here shortly and i will totally forget everything... basically though, for more help we gotta know where that air is comin from, how cool it is, and where it is going... dont worry man, you will get it sorted...

if youre temp your pullin into that room is any higher than high 70's the results will not be good and you may need to get an AC unit... as for where you can find a blower exhaust, just get a 4" or 6" inline fan and make the ductwork...

Thanks for the advice, i was looking at inline fans but i didnt know if they were powerful enough. The intake air comes from my room which is usually 72-74f. the exhuast goes back into the room but near the door which is always open. Do you know where to buy a cheap inline 6' fan.

My canopy level gets to the mid 90's without apparent distress to the plants. Mostly, I'm in the high 80's to mid 90's when the lights are on. Night time can go down to 70 degrees.

Of course, I'd rather be in the low 80's with the lights on. I'm just saying maybe the low 90's isn't the end of the world.

I have definitely noticed some plant stunting, I think most of all temps effect different strains in different ways. I need to lower my temps, I'm going to look at some online fans but I wanted to see if anyone posts a trusted website I can get one from.
