Cheap exhaust system?

make sure you have negative pressure... u might need to turn the speed up.

Everything in my closet is sealed except the bottom of my door. When i shut the door to my closet.. you can hear the air moving under the door when ur head is about 1 foot away. It will blow out a lighter when an inch away from the bottom of the door.

Post up some pics.


My guess is that the slower the air can move through the carbon the better it will filter. So,

Seal up the box (i would recommend having the intake as low to the floor as possible, to pull in the coldest air in the room)
Then adjust your fan, start slow and work your way up.
(you will want the fan to just create enough air movement to eliminate smell, cool the grow and keep negative pressure)

Also... Don't forget to get the ONA Gel. You could even rig a pc fan to a hole cut in the lid of the jug.

Ona gel is coming, i will get it. There is negative pressure in it, i have 2x intakes so there sucking in good air ill take some pics brb
Damn cameras dead pics will be up in a hour.

my intakes are 2x 2" pvc pipes. When i have it on medium I can feel the air getting sucked in pretty good.
Negative pressures there, when i turn it on low. I can still feel air going in just not as much.
I'll try with slower fan speed, but is a bong rip too much or should it filter it?

<-- those are my intakes my exhaust hung on the ceiling of the box.
Need more flex duct, going to run it into a box with ona, this should work. hopefully

Make sure all the duct work connections are tight... I only saw duct tape... You should get some worm screw clamps or at least zip ties...
As far as the bong rip test... I'm not sure... I have never done that... I don't smoke actually lol.

I think a good test would be to get a qp or half p and spread it all out on a tray inside the box. But I don't know if u make moves with that much weight...

Looks like u got a nice build there though... Take lots of pics as you build it.. I would like to see more.

My box thread, ill be throwing more pics
The duct tape was because the ducting riped a bit.
Will be alot more upgrades on the venting, thats just the start.
