I got a question?
I was just wondering if there was any other ideas/setups out there that keeps hps low and cool. I plan on using a 250w hps ina closet with a small 4' statinary fan and a ocsilating 3 speed fan simliar to "ionic breeze". I already put hps in there with no fans got up to 99 F. Im lookin 4 cheap not a cooltube or dayton or a/c types thanks
happy growin & smokin:weed:

You could get hoods with openings and just use ducting that they use for dryers then run from one side to the other light this.

Intakefan|____light__light____|exit


__=ducting
Light= your lights
| |= walls
Exit= Exit
Intakefan= Equal any kind of fan you can mount to push cooler air through ducts and your lights keeping temps very low. An intake fan..like a 4 incher..should do the job nicely.

with the fans in there it should lower the heat but yer just cut a hole in the roof and stick a extractor in or leave the door open.

first put a bowl of water in there to get ur humidity to around 60% then cut a whole in the tarps and stick in a extractor fan. iv also heard of people putting a ice cream tub of water or something in the freezer till frozen then stick infront of fan. only thing is u have to put a new one out every day or something.

You need circulating ventilation, cut a hole in the top of the tarp in the doorway, then cut a similiar size hole in the bottom. This way it will suck cold air from the floor up to the top and blow the hot air out.

I have some of the same problems most of the time i just leave the door open a bit but i would like to have a way to come down to around 80 im at 86 and i use 3 out fan's and 2 clamp on fans that turn. should i turn one of my out fan's in to a blower so it blows out side air mid 70-80 in to the grow room or will that be an issue?

does that really work to raise humidity? ill try that ghetto idea and get back with u, tried the frozen thing before lower temps by 3 degrees F at most never will do it again just wastes space

so thats what i did last night i turned one of my out fans to an blower now it blows outside air through a filter and now i can run a 600w hps and 4 200 cfl and it only gets to around 82. anyone have a problem with outside air coming in i did run it through a hepa filter first but can things get through that and screw things up?

are u pulling air straight from outside or from still in the house? if its straight from outside i always like to have a bit of fly screen or something over the end so no flys get through even tho half of them would prob get chopped by the fan. whats a hepa filter?. benzo just checking out ur grow now.

Im pulling air from outside and its been a few days it has been great.

A hepa filter is kind of like one thats in a vac-cleaner seems to block alot and not effect the air flow that much. I push the out side air over the top of the plants they seem to like it.
