Will check video in a minute. Yes, I do know something other than trash bags. Get ya some panda plastic, white on one side (will face grow area), black on other side (side you will see when you open door). Cut it big enough to completely cover door and about 6-8 inches around frame. Once you have done that you can cut it down the middle and buy one of those zipper/velcro closures things from bghydro and you now have a pseudo d00r that is light proof. You could then stick a few staples in it to hold in place, or you could staple it to 1x2's and then screw them in the studs in the walls using drywall screws and then I promise you that would not have any light leaks. The side of the 1x2 you stapled it to would be the side against the wall. That way you have the staples, plus the pressure of the 1x2 pulled against the wall with screws to hold it in place. This way you wouldnt always be pulling the staples out and ripping the plastic, etc. That panda plastic is 6mil I think, its damn sturdy. You can even line your walls with it instead of mylar.

Here is a link to that closure:

Here is link to panda plastic:

Scroll down the page for that second link to see the plastic.

On other sites I have seen entire veg/grow rooms built with panda plastic on a wood frame and using that zipper/velcro thinger I am talking about.

Another question. Is there electric in this room ? If so, does it have grounded receptables (3 prong) If you got an extension cord running into that room that would certainly get some attention. Ideally, and again not an option I know most likely, but is your outlets for your grow on seperate breakers. For example, if my lights would ever kick their breakers, the fans for the cool tubes are on their own breaker and timer so they keep running to cool the lights down after they go off. And REMEMBER, never load a breaker over 80% of its listed Amperage.......NEVER EVER EVER !!!!!!!!!!

Yeah, the carbon filter idea is worthless if blowing the air back in the same room. As far as you needing to buy ducting, I understand it comes in 25' lenghts only, but you can cut it. Thats certainly not a big deal. I'd have just enough to get into that space versus cramming 20 feet of it back in there.

I am close to raising the white flag on this ventilation/odor control issue. I mean there are basically no options I can possibly think of. Unless one of those filter things you had link to works, thats about it. Harder than hell to vent something when you have no place to vent to. Thats pretty simple to understand.

D00d, is the house AC'd at least ? (please say yes)

And no, I dont have any messenger things. Sometimes I am deep thought at the computer and dont want to be interrupted by someone asking me some mindless question about nothing that means nothing. Like where my wife is or something because I wont answer the fone to tell them. I got rid of for that very reason.

Fuck, Bob Villa dont work this hard figuring shit out.....LOL

I am leaving here shortly, but I will be back on topic later this afternoon upon my return. Wife wants to go someplace and get something for something and insisted I go. She told me what it was, but as usual I forgot to pay attention.
