Hey all, I'm new to this forum but have reading this forum like it was the bible for a couple weeks now...

I live in an apartment like many other indoor growers and I am looking for a solution that requires the least damage to the closet for Ventilation. This needs to be a completely STEALTH grow. I have heard of others making custom doors with vent holes and replacing with orginal when they leave. This method doesn't suit me well because it very noticable if inside the apartment. So basically my main question is as follows:

Is it possible to devise a ventilation scheme in a closet that is completely stealthy but requires no/min. damage?

Welcome to the forum. Now that you have started four threads, all while I was stingy enough to sleep instead of being there for you, No. You are not going to be able to reinvent the wheel either. In order to do stealth ventilation of a closet, you have to have access to an attic space directly above. Unless you are on the top floor, and unless the building has a peeked roof, there isn't an attic space above. If you want to lightproof around the door, don't do it at the door. Do it by making a Panda Film curtian on the inside. Attach it to the sides of the closet and across the front. VV

if you ran it to the attic wouldn't it be easier to pick up with infared? what about venting under the apartment?

you dont need alot of ventilation you just really need a fan and open the door at least 3 times a day and it will be fine.

They dont pick up the scent or the little bit of heat that you will be venting in the attic. And if you vent under the apartment then the smell will come out down low and is more easily smelt. That is why people vent in the attic. The scent is up high and the wind usually caries the smell away and no one even smells it. You need to read the faq section more to get an idea on what you should do. I feel for anyone that has to grow in an apartment. They have more guts than me. I would not attempt a grow if i was doing it in the place that i had to rent. But that is just me. Too many nosey landlords that will come in when you don't know it and the will snoop threw you shit. I just dont trust them.

what if you were using an enclosed style with no smell?

Yea, i guess you could vent under the apartment if you use a carbon filter on the vent.
