Ventilation question??

Ok, setting up for indoor in the soon future and was wondering how many cfm i need to move to have control of this room? its 838cubic feet. i wlll be running a 600 to 1000w hps. my intake will be coming from the floor and exhaust into celing. I was thinking every 5 min replace the air so 180 cfm should be ok? the smallest i think i'll go is 270cfm. How am i doing fellas?

Here's a CFM calculator

they recommend an exchange rate of every 1 - 5 minutes, so to be on the safe side let's go with 2 minutes = 419CFM

The Soler & Palau TD-200x pulls 419 on the low setting. perfect

That looks great. yea thats what i was thinking move more air. Thanks for your time

Erm I am confused the CFM converter says I need to do 2.4 every 5 mins in a 2x4 closet my timer does 15 min intervals at lowest ? I have 2x 6" fans for exhaust how do I know wat is right?

straight g you should run a smaller fan continuously. like a amp fan from raidio shack. dose that make sence?

Sure does, thanks4 ur reply will it just plug in?

Peace

never used one i know they use em out of computers though. which should be set up for 110 a wall socket. look up computer fans and see what you come up with .

Cool I will look into it thanks4 the advice, y dyu reckon no1 has replied to my thread Iv had like 80 views and no replies dyu think ive done something wrong I was just trying to apologise for thread jacking before I asked for advice??

STRAIGHT G an old phone charger or something to that effect will work. PC fans are 12V DC so just look on whatever you are going to use and it will tell you the output power. Black is ground, red or yellow is hot. although it should work either way you wire it. or if you go to radio shack and get a 12 volt adapter all you do is plug it into the wall and put the wires into the little holes it has. youll see when you get it in your hand. they are cool because you can switch it to 3 volt 5 volt or 12 volt for 3 speeds. let me know what you do and how it works.
