Searched but couldn't really find anything relevant to my situation... lots of stuff came up.
I'm starting a closet grow soon, it's an ok sized closet that I can walk in and lay down in, and it's about 8 or 9 feet high, i dunno. I have a 400 watt hps I plan on using, only problem is the closet has no leaks in it, and I'm afraid it's gonna get really hot in there. Am I going to have to cut a hole in the door or something? Having to open the door every few hours would get annoying.
I rent, so cutting a hole in their door wasn't an option. But I lucked out and found a "damaged" (small scratch that a bit of paint & putty covered) door that was the same size at the local builder supply for $10! The old closet door is taken off and I get my new door ready.
1) I drilled a 3 inch hole through the door to fit a small fan I already had. The hole is about 6' 2" from the bottom of the door.
2) I got a thin piece of wood that was about 4 x 18 and some contrasting wood trim that was about 1 inch thick. I cut the trim so the 2 long pieces were 18 inches and the end pieces were about 7 inches (to hide the cut ends of the long pieces).
3) I then split one of the long pieces of trim so it was about as thick as the 4 x 18 board.
4) I assembled the pieces to make a very shallow box with one side much lower than the other 3. From the front (the bottom of the box) you can't tell that there is a vent on top (unless you are about 6'9" tall, lol). The split trim side forms the top of the coat rack- and the vent to your closet.
5) I added some brass coat hooks, varnished it and hung it over the hole. The fan got mounted on the other side with some foam rubber padding between it and the door to lessen vibration. Air is exhausted upwards through the hidden vent. :D
It looks like a kid's wood-shop project being proudly displayed by Mom! :D Get a GOOD fan- mine is cheap and you can still hear it hum :( , but otherwise, it works OK.
Granny :hippy:
I vent into my attic, have the fan and filter up there, actually just checked the filter still blowing nice kitty litter smell after 3 grows! anyway its pretty simple setup, i let it suck air in from under the door ( has a big gap so it had plenty of area) and made a shelf in there a foot up from the ground so i could put in 4 abs 90 degree elbows so the light would not leak.
I have a similar situation, my whole building is made of block, I am the super and wanna start in my closet instead of a grow box in the closet. There are no holes or anything and it has those shitty hanging sliding doors that you see in apartments all the time. What I plan to do is just inside the door is put one of those room divider tarps with a zipper in it just inside the sliding doors so it still looks like a closet. There is another small shoe closet next to it so I plan to make a 4" hole in the drywall ( easy to repair with drywall, tape and mud, sand then paint, will look like it was never there) going through to the closet nextdoor with a carbon filter hooked up so it doesnt smell, and leave the closet next to it open all the time so it sucks all the hot air out, especially if you have a cool tube this would work, also i find just basic air circulation helps some, "blowing the air around. so adding an oscillating fan (which you should have anyways to simulate wind) will blow the air around.. you can have a grow without a fan unless its outdoors, the lights required most always produce large amounts of heat. I would recommend purchasing a small exhaust fan to blow over yous ballast and bulb to pull the heat off it and another to pull the air from the room, but it must vent to out of the room or your just moving the hot air around...
No way you can run a moderate power HPS in the closet you've described without any forced extraction. Yer plants will cook. I have a 2' x 6' x 8' closet and I run a 5" extractor (no carbon filter or silencer), two 12" recirc fans to exercise the girls and keep airflow good, and a 4 inch active intake for fresh Co2 laden air. All this to keep a 1000 watt rig from giving my plants a permanent orange afro. At some point you will have to cut and run.
Like the idea of buying spare doors to cut and then replace them when you move. I did the same. You can't have your cake and eat it. You're either growing or your an angelic tenant. Make your mind up and start having fun.
