take your L x W X H ....this will get your cubic feet....if you want to clean your room once every 5 mins divide by 5 that will be your cfm needed

Example room is 8 ft x 8 ft x 8 ft = 512 cubic ft......512 / 5 is 102 cfm

its in a hot attic so i figured the more the better so 435cfm but would the conversion from 6" to 4" be worth it

take you L x W X H this will get your cubic feet

its 4 wide 4 long and 5 high with fresh air intake so 80cf but like i said its a hot fucker in the summer

its for a cool tube not the room air

i use the 6 inch duct booster fan to cool my 1000w hps and it works fine.

this is my 400w hood with a home depot 4 inch duct booster fan and a home made air filter and my light is good like this.

OK but it will not touch any air in my room one bit in and out the window with a cooltube in the middle get it?

hey sick check out my attic...https://www.rollitup.org/grow-room-design-setup/309747-right-way-d-attic-grow-6.html...... i send a pic to it! if your room is enclosed well like mine what i did was installed a roof vent that is motorised with a thermostat built into it and it moves bout 1400cfm out of he attic to help keep the attic cool!! and it gets hot and humid as fuck around the room but not it because mine is very well insulated but the fan kicks on at 85f and cools the rest of the attic
