Venting to the attic?

[M.B.A.]

Ok this is my situation, I want to invest into a 4'x4'x6' GrowHut, I am growing in a 15'x6' Walk-in Closet, my question is if I hooked up a GrowHut setup, would I be able to vent the exhaust from their into my attic access(picture) in the same closet on the roof if I made a custom panel to hook the tubing to?would It save on Heating?

Sure you can, I vent into the attic, and actually have the fan and filter in there as well. I dont think it will save you on heating, too drafty in the attic to make a difference.

ok, was thinkin of putting a homemade carbon filter on the exhaust too saw the DIY on here for that

MBA, you are fortunate to live in a warmer climate. i've heard of folks needing a whole new roof because of venting warm air from their grow room into the attic when its cold. the differing air temps cause moisture and slowly deteriorates the building material.

You should not vent directly into the attic, as warm and humid air can cause mold to form. Mold will make your house very difficult to sell.

There should already be at least one vent built into your roof for bathroom fans. Check your attic and you will likely see the duct hoses leading to the roof. Go to Home Depot or whatever and get a splitter for the ducting. You should be able to share this roof vent for garden venting purposes.

The only problem I know of with this setup is that warm air would be vented often from the roof and would be visible to an IR camera. However, this is expected since bath fans and kitchen fans usually vent this way.

If you must vent directly into the attic, I would recommend installing a traditional attic vent fan with a humidistat. Roof and gable models are available. The humidistat will turn the fan on when a certain humidity is reached.

Making sure it's not a shared attic is likely important, too. I lived in a condo and the moron next-door thought that the attic would be a great place to set-up his train set. Could smell the booze and smokes from our place. Never made any noise, but I did have shitloads of dreams that I was Sam Malone, from Cheers. :jointsmile:

Very good point Rusty, I vent into my attic and my house is attached to next door. There is a brick wall between the 2 attics, but the mortar between the bricks is pretty crappy and I found a few holes in the mortar (not sure if they go right through though). So as a precaution (can't be too careful), I went round and sealed as much as I could by putting a plastic sheet up and sealing around the edges with silicone sealant.

Hopefully that will stop any odour passing through......so far so good! :thumbsup:
