hey there, thought about setting up a little grow room in a closet and it worked out with CFL's but I've recently upgraded to a 400w HPS system. This is where I've come into problems, specifically with heat.
My set up is a closet. It's ten feet wide, 2 feet deep, and 8 feet tall. It has a shelf that is about 5'10" high. It also has 2 doors, right next to each other, that both go into the closet.
this is what it looks like from the outside.
This is a simple drawing of what it looks on the inside if i were to remove the doors and the rest of the front wall.
I took some paneling and kinda sealed up the portion of the closet i'm using as the grow room. I used duct tape to seal it to the wall for a mostly light and draft proof seal. The top of the sealed off portion is at the same level the shelf is. The light is a 400w HPS bulb inside of an 8 inch cooltube w/ wing reflector. On the bulb side of the cooltube I have a cheap 3 speed 8" fan hanging and blowing into the cooltube. On the other side of the cooltube I have a 6" diameter section of ducting that hooks up to an 8" inline duct fan from home depot. That inline fan is in a hole on the top right back portion of the panel i used to create the grow room. I have my intake on the front bottom right section on the floor. I had a fan blowing into it, but decided to use the second cheap 8" fan to sit on a shelf in the grow room and point in between the lamp and the top of the plant i have in there. I've hung a thermometer from a piece of chain at the same level as the top of the plants and since i installed the HPS 2 days ago, it hasn't been below 86 with the lights on.
My plant is starting to look a little withered and I really don't want to lose my baby. I want to have the door with the plants in it to be shut most of the time and i don't mind leaving the second one open. I assume one of the issues with my ventilation is because I have the exhaust going into the rest of the closet and have the intake coming from a hole facing the same side of the rest of the closet.
I really didn't want to cut a hole in any of the permanent walls or ceiling, but would it help out a lot more if i just went ahead and cut a hole in the roof or wall to vent my exhaust into in order to get all that hot air out since i'm intaking from the same closet? does it make that much of a difference?
Would really NOT like to cut into the door, that is why i created it's own sectioned off area. I need to be able to close the doors, at least for a little while, without noticing anything going on in the closet. not worried about smell.
I'm open to any ideas, just need to get it cool fast! Thanks for the help.
