  • can some help me figure out the fan and filter i may need? im kinda lost with this but here it goes....
    im using i small grow box. its 34"L x 13"w x 38"h so that means i have a 16,796 cubic inches which converted is 9.72 cubic feet? ok so roughly 10 cubic feet would mean what kinda cfm do i need? cfm= cubic feet per minute and the smallest i see is 170 cfm so wouldnt that be huge overkill in my lil space?
    like htg supplyer says     "For example, if your growing area is 8 feet long by 8 feet wide by 8 feet tall, it contains a total of 512 cubic feet. To treat this area in five minutes, you would need to use a fan with a CFM (cubic feet per minute) rating of approximately 102." so my room is like a 1/4 of that size so that means i would b ok wit like a 25 cfm fan? and also to boot i have to worrie about how loud the fan is. so ive also been looking at a fan filter combo good for my small space thats very quite and as cheap as i can do with it being good craftmanship
    thanks for any and all help    ​

everyone feels your pain, fans are one of the loudest parts of a grow room, i have a 6'' turbo with a carbon filter and the sound of the fan is just as loud with as it is without. build a little wood box around your fan and hang the box with your fan on a suspended line in or out of your box. it takes the vibration from the fan. your left with just the airflow noise.. if i could invent a silent fan for grow rooms i would be a millionair KEEP ON GROWIN..

it say's it'll treat 500 sq feet in 5 mins so since your room is 1/4 the size run it 1/4 of the time? i'm still new to growing so i might be wrong
