Setup is an 9x9 foot room, 4 600w aircooled lights, 32 plants. A 6" inline fan is pulling air through the lights to the outside and on the other end a 6" inline fan is pushing air through the lights to the other fan and outside. Then I have an exhaust with a carbon scrubber with a 6" inline fan pulling air to the outside. I also have an intake pulling air from outside into the grow room with a 6" inline fan. Plus two oscillating fans. Still it's stuffy in the grow room like it needs more air. I have a spare 8" inline fan, so I was thinking of using it instead of the 6" on the intake. What would that do to the negative pressure and is negative pressure essential anyway? Any other alternatives?
Need help with ventilation for stuffy room
