set up question??

hi i am living in the process of growing a couple of plants in a closet.they are nearly a month old and doing good.i will be making a number of clones off theses 2 plants aftr anothr month or so. when im flowering these clones ill need to take them from the closet and put them in my growroom. my growroom wil be an area sealed off inside my bedroom wit the an opening on the top to leave out hot air. i purchased inline fans for ventilation but they are too loud. wud a few oscilating fans be sufficent to push air into the room and have the top of the room open to leave air out??. i wud also have a co2 container in dere and have my window open at all times. wud the plants grow in this situation?? i cant have intake air from outside because it b too cold!! i ewill be using 800w of hps in a 4 x 4 area.

never hear of an 800 watt hps. i would be more concerned about a filter than a co2 set up and if you leave the top open light will grt in during the dark sycle. mabee there is something wromg with the fans, i have a 450 cfm fan and i dont even here that at night. you need to exchange the air every 3 to 5 minuites i dont think oscilating room fan is enough. do you know if thier females or not. i wopuld take a top and flower it to see and then it will bush the mothers out to clone more.

i was going to black out the room by covering the windows wit black platic. wud that fan be strong enough to cover the 4x4 area both for bringing in and extracting air???? using inline fans t100 think dere called. quite powerfull thats probably why so loud!

i could vent my whole house with the one i have. you dont need an intake fan, just exhaust. do you know how to figure out how big a fan you need? 4x4x6= 96 cfm then you need to add a bit for filter back pressure so i would say about 150 cfm and you will be ok with one fan. i only assumed the hight was 6 foot. so take width x depth x hight = cubic feet per minuite needed. you have to be carefull with the light leaks, it only takes as little as a lighter on for 1 hour to possibly hermie. neighboors tend to get suspicious wit something blocking windows.

im using 2 x 400w hps. my curtains are closed the whole time and have black plastic covering the curtains. absolutely no light gets in. have no neighbours at the back! wud the exhaust do so. where can i get it. livin in the uk can i get it on the net??? wasnt sure about what fan i need so just bought the tt100. thanks for ur time...
