can i use a 4" In-line Duct Fan instead of a Centrifugal Fan in a hydrohut mini
This is for my veg room .. Im trying to save a few bucks .. Does anybody know the answer ? all my money is going to my flowering room
Can i get by without an exhaust fan ? Do you need a exhaust fan in the veg room And just using table fans to cool the hydrohut
veg room lighting 250 MH NONE cooled hood

I am using both of my fans for my flowering chamber, none in
my veg. I air out the veg. chamber as much as possible, but
haven't had any noticeable problem.
However, the more air-flow, the stronger and thicker your
stalks will be.
