Vortex inline fan question

**dj crane** · 05-03-2009, 08:43 AM

i have a 4" 177 cfm fan exchausting my grow room, my temps are still kinda high and i know if i turn the fan around and have it sucking in air rather then sucking it out, it will drop my temps, but i am worried it might have adverse consequences, such as bringing in mold spores or raising humitity, or something else i can't even think of, any knowlege lent would be much appriciated!!!

is there a fresh air vent letting new air into the room?

You are going to stink up the whole block doing that.

HEPA intake filters are made to prevent intake of spores, bugs ect. Best of luck.

i am venting outside now, i want to swtich to incomeing only, not stinking up the block cause the air from outside will be sucked in, did you think it backwards or am i misunderstanding what u are saying?

Right now i have only negative pressure to bring in new air, and a fan laid outside the door pointed at the opening

No your right, I assumed you were using a carbon scrubber or something to clean the air before you exhausted it. Sort answer is : Yes changing you ventilation around will drop your room a few degrees.

I was thinking the same thing man, right now i have a canfan 4inch sucking air in and it works great just have to put some airfillters between the outside and inside. Then i have a 6inch Blower hooked up to a air ducing T with a 9inch house fan on the other side both fans sucking air out.

Do you have a cool tube ??

I setup a cheap cooltube i made durning the grow it helped out allot bringing the temp down, but still had problems every once in a while.

I was planning on making a way better DIY cooltube after my harvest, take my 4'' canfan hook it up to a Carbon Fillter then the other side to my light so air gets sucked in threw the fillter passes threw the light (cooling it down) then out the room(were i used to bring air in from)

So i think i am going to use my 6inch Blower as a intake and the 4inch canfan as my outake, i believe you want more bad/hot air blowing out then cool air blowing in

Still have to think of where i am going to pull my new cool air intake
