Ok heres what i have. I have read a lot about ventilation setup in a tent. i am growin in a grow tent in my closet the tent is 20x 36x 64. the closet is 5 foot 7 inch wide, 2 foot deep, 8 feet tall. i dont have any way to vent outside the closet. I will be running a 400watt hps by the way. my plan is to have a cool tube reflector with a 6 inch incline fan in it (250 cfm). i will have a 4inch incline fan (80 cfm) at the bottom of the tent. and finally a 6inch incline fan (170 cfm) at the top with a carbon filter going to the top of the closet. now this is my first idea at a ventilation setup so i know its probably ganna need some expert advice

thanks for reading

Wait, so you are going to vent the cooltube into your growtent?

You need to have the air coming from the cooltube vented directly out of the closet. If you dont have it leave the closet, you will simply be recycling the hot air from the 400w HPS, and your closet will reach 120-130 degrees F in no time. Is there an attic above your bedroom? Punching a 6" hole in the drywall isnt THAT big of a deal, and would allow you to get rid of ALL of your hot air.

Thats not wat i said , the out take fan from the top of the door will have 2 intakes 1 from the cooltube and the other whole for the rooms air to go to the top and exite ther

Ok. Do you plan on keeping your closet doors closed for any amount of time? If so, you need a way to get the heat out of the closet. The heat from your exhaust from the top of your tent will eventually heat up the entire closet if its not vented, until the intake on the bottom starts sucking in hot air, and then it compounds the problem. If you leave the doors open all the time, then you should be fine. Your room might get a little warm, but it should be fine.

I am not just speaking out of my ass. The heat needs somewhere to go. A 400w HPS, as you know, gets REALLY hot.

I understand what you are saying, kind of. Where does the hot exhaust air get vented to though when the doors are closed?

well bottom line is i need to do something, killed first crop to heat. if i vent to the attic wont it be a dead giveaway for thermal imaging

Your attic is probably 140 degrees during the day. And maybe down to 90 or so at night. I highly doubt thermal imaging would see anything, not to mention I don't think they can do that without a warrant.

i dont think you want to make a hole in the door. A hole in the door means you have to buy a new door when you move out. A hole in the ceiling means you have to get some putty and some paint and make it look semi presentable, because no one is gonna be looking at the ceiling of a closet when you move out.
