Need a way to create an air tight door...

About to start my first closet grow. I need to make the room airtight so the air only comes in through the ingress pipe and leaves through the egress pipe. This wouldn't be much of a problem except I still need a way to get to my plants and other hardware.

Rather than just have a rolled or zippered mylar flap as the door, does anyone have a way to create an entrance that is sealed against air (doesn't have to be max efficiency. just enough to put most of the air through my CO2 filters) but still allows easy access?

Yeah your best bet would be to buy a pre-hung door, add extra weather stripping/rubber seals, and/or shim the existing stripping. It'll never be an airlock but should be more than adequate.

I don't need it to be perfect. I'm absolutely terrible at woodworking so I'm not really sure how to do this basic stuff.

Try expanding foam around the edges.

i made one, just buy weather strip, put some locks on that can hold it tight against the seal.

I'm putting my grow box inside a closet so I'm gonna have to build the door separately I was hoping someone would have a cheap and effective way that I haven't thought about yet, but the weather stripping idea works. It's only for a few months anyway.

it's for smell control. not light.

Hi I'm not really sure wat your asking but here goes . I work in the asbestos game and the way we make airtight rooms with access is a polythene door with a weight at the bottom . It creates a vac like room .

my grow space got shortened. Instead of having a room to do it in, I've moved it to a closet. My cheapass plywood box is going to be 34" L x 78" H x 22" W. I can use silicone caulk around most of the edges to keep the air from escaping, but I need a way to seal round the door so the only way air has to travel is in from my ingress and out through my exhaust which goes through a few tiny carbon filters that are coiled on the back of the box like a fridge coil. I want the air exchange to go through three different carbon filters before leaving the closet and I plan on running that ghetto bucket and pump thing with pine sol in it to catch any leftover smell. I live in a duplex and I don't want to cut a bunch of holes in the walls.

weather stripping is your best bet, i didnt weather strip for air leaks, i did it for light leaks, but still......

You need a vault door. Keeps everything in and everything else out.

PCV, 2 mil black or white poly, and a lot of duct tape.
And weather stripping.
