400 CFM exhaust 240 CFM intake Any problems? 4x8x7 TENT 1000w MH air cooled hood

[yeti5508]

i ordered a 400cfm exhaust, and a 240 cfm intake inline 6 inch fans..

my setup now is a 6 inch house fan up pushing air threw the hood and out the vent and out the tent,and another 6 inch house fan on the floor next to the open vent blowing in air from the room... temps are 86-90 day,65 night

thast not good i know growth stunts at 86 but i didnt think i would be a t risk of fire its not that hot in there i can chill in there with them for as long as i wanted as long as i had a drink ....

i just got my big fan today should i go ahead and set that bad boy up...


I wondering if i got a problem of making to much air leave the room and not enough coming in..

fans work better when they pull air instead of pushing, try putting your fan at the end to suck air out

I would say try to get the temp to drop a little bit with that new fan. Your temps are not outrageous and I wouldnt worry about setting a house on fire @ 90 degree;s LOL Also as one dude said getting the fans in the right spot will help too.

use passive intake.. i heard it should be twice as big as the out take. i got a 4 inch out take, i got 2 4 1/2 inch passive intakes.

i hooked up the 400cfm fan and its working great i set it up to pull the air threw it.....
havent been home to check temps im sure they will drop though.....

whats passive intake like having vents open?

yep, i built mine myself. i just drilled 2 holes. one on each side. the air sucking out through the top will pull the air in through the bottom and circulate it. i got 2 oscillating fans 6 inch. one on each side in the corner on low blowing across the tops of the plants. i dont think two is needed, but it rather have more then not enough and i got a 400w not 1000w. i was going to upgrade to a 6 inch fan and filter because i currently got a 4 inch but i dont know if i need a 6 inch since it can cool a 1000w lol.

i have vents open in the tent for now..

when i get my 240cfm intake fan il be closing the vents up, hopefully making the temps drop more...

oh and temps are now 82-86 after fan,,hopefully will be 75-80 after intake fan

you shouldnt need a intake fan. the fan you got sucking the air out will make air go in through the vents.
