Hey there great info! From what I've read I'm goning to try and apply it to my situatiuon. Maybe you could help or advise? I have an old dryer exhaust in the basement that I want to convert to a fresh air intake. I think its only 6', my question is if i get a large enough centrigufal fan to suck air inside from outside could I split the intake in to a cooltube 1000W Hps and the other spit use as fresh air for the room or would that cause no vacum pressure and just screw up with cooling the light?

any advice would be a huge thanks!!!

do you think i could attach some 4" ducting to a batwing reflector? and a 4" inline fan to that my room is only 38" widex42"deep and 43" tall. i will only be using about 2-3' of ducting to an 80cfm 4" inline fan for exhaust. i will be using a couple fans blowing on the lights for intake. i dont have an aircooled hood, which is why i want to know if i can attach ducting to an "econowing" batwing reflector. i havent turned on the setup yet so i am hoping my temps dont exceed 80 degrees F.

heres my growspace - bottom half of a closet


i want to attach a 4" inline fan for exhaust to the plywood right by where the door handle is on the right side. intake would be an 8" upside down fan on the left side, blowing on the lights. the room is not "sealed", there is about 4" from the door to the plywood, and about 2" from the plywood to the door frame. i wanted to fit the 4" inline fan inbetween the right door frame by the door handle. like i said the room is not sealed and there is no Co2

btw i would blow the hot exhaust air from the lights to the top half of the closet. and pull cool air right onto the lights on the left side of the room, near the closest edge of plywood. right by the door hinges.

Wow nice thread it has got excited to redo my whole vent setup.
How does that system vent the room automatic baffles or is it a seperate setup.

Sub, what if i'm only venting 1 room thats 10 ft long 8 ft wide 12 ft tall? how would i easily and cheap as possible vent my room?

by the way i'm only running 2 1,000 hps.

im re doing my whole setup for vent i have a 8in 500cfm duct fan witch sucks air through the filter that runs through the cool tube an im shootin it up an out the room. my intake is in the other side at the bottom its a lil over 4 1/2 inch intake.

Do vent your room directly into your attic? If so, how do you prevent mold build up in the attic space from the moisture leaving your room?

The attic is ventilated but thats only a small problem ny system is pulling outside air through the hoods and expelling it so its not picking up loads of moisture on the way passing through.

Hey subcool, this is a great thread with some awesome info. I got a question for you though. I plan on using CFL's inside a cabinet around 78"H x 48"W x 24"D. I will have a 4" Vortex Inline Fan run to a small section of 4 inch piping that will be connected to the Can Carbon Filter. This set up will exhaust straight through the carbon filter into the room. I will also have a type of Hepa filter/air cleaner inside the cab. So, my question is... How or what will I use to bring clean air into the cab and how would I set it up?
