So glad you mentioned this, I was curious if I would need make/purchase a high cfm kit. I don't have any negative pressure at the moment but I also have all mesh lined openings "open" lol. Alot opening happening geesh!
What speed is your exhaust fan on? And is it constant?
Yeah I keep it on constant
Have the fan in my loft ducted to a carbon filter in the tent
Works a treat
I used to use a 4 inch connected straight to the carbon filter in the tent
But in the loft the 4 inch didnt have enough power
You can open the wee holes abit I closed them all tight start of this grow
I haven't seen it being like that much suction in previous grows
Could do at like
