2 fans helps with placement

400w hps cool hood
2.5x2.5x5.25 tent
6 in 440 cfm inline exhaust fan
and this is in a closet roughly 3.5 times the size of the tent.
newly acquired 6 in 240 duct booster fan



currently have the 440 cfm inline fan connected pulling air out my tent and light.
set is
carbon filter >duct> cool hood >duct>inline fan >duct exhaust

(the inline fan is currently on the outside of the tent sitting on top)

tent still getting too hot for my liking
house temp 75 , tent temp 77-90

& i currently have all 3 of the vents at the bottom open for passive intake.

wondering
should i use this 6 in booster fan to bring air into the tent at the bottom with some duct ?
( how do i do this ?)
or
should i use the booster fan to cool the light by itself?

bump anyone ?

should i use the booster fan dedicated to exhausting the light.
or
should i use the booster fan to pull in air from the bottom ?

well i can see the issue in your first pic

u are dumping hot used air right back into the middle of where the is coming from ........u need to ejected the used hot air outside the air cycle used for the tent (Hot air is raising the temp of your cool higher co2 lvl air) heating the air and lowing the over all Co2 lvl the plants are getting

dump the air outside the house

I dumped my exhaust through a hole in the ceiling after the charcoal filter. Use booster fan to draw air into tent. Pipe hps from outside to hps to filter to hole in ceiling. Save hole cutout to put back later. Problem solved.

Its ideal to run it outside, but if you can't, run it into the wall lol
