Avoiding cutting an exhaust hole in closet

My friend Bob has a great little mother-clone grow space in his closet.
He avoided cutting a hole in the wood, although adopted putting a few small nails in it.
First, he took a sheet of clear, flexible plastic lying around the house and cut two pieces.

The first sheet he cut was the width of the closet, and half the height. He nailed this just inside the doors, sealing the top half of the grow space behind a transparent '4th wall' (even with open doors). Bob then cut a 6 inch round hole for his fan to poke through, up the top of the plastic, a bit left of the middle. This allows the fan to blow out with the left door a bit open, and the right door closed.

The second sheet he cut was half the size of his floor space, but slightly larger in one direction. If it was used as a floor mat for the left side of the closet, a few inches would be pushed to stick up against the back wall when you close the door.
Bob positioned this plastic horizontally, on the left side of the closet, raised up to a few inches beneath the fan. He nailed it to the walls and duct taped the front right corner to the middle of the front first plastic sheet.

Bob hung his open batwing hood in the right half of his closet. It fit snuggly with an inch either side to the walls and the side of the second plastic sheet, which was drooping from the extra size.
Bob poked a hole a hanging rope through the second plastic sheet, tying a knot in the rope. He could therefore adjust the height of the drooping second sheet a bit by changing the height of the knot on the rope, raising and lowering it when doing the same to the reflector.

This setup appears to be extremely advantageous for Bob's air cooling technique - forcing air to be sucked up all around the bulb, without any glass between the bulb and the plant.

Bob keeps a mother in the right half of the closet, and roots clones in the left half, with a supplemental small ~24 watt compact flouro. This hangs from a rope, which of course needed another hole poked through the second sheet of plastic.

Finally, bob nailed a towel hanging across the left half of his closet. It can be lifted like a wedding veil and stuck above, for access to the closet.
It has a hole cut in it for the fan to poke through, and hangs to several inches from the bottom of the closet. This provides a reduction in light pollution to his bedroom, while making for a nice low passive intake zone. It is a white towel to give some internal reflection, but Bob is considering hanging a second, black towel over it for extra stealth.

There's been no melting yet - it's only a 250w compact florescent, and there's an inch between the plastic and hood with a lot of air flowing through it :)
 
Often here we get growers wanting to grow in their rented abode

the easiest way imo, is to get a new door in and fix an extract fan to the stop of the door

with passive inlet holes at floor level

hot air is sucked out at the top

with cool air being sucked in at the bottom

once the lease is up

replace the original door

later much later that used door makes a great germing table ,..lol

good luck
