Hello. i am growing in an undertsairs cupboard i dont know the measurements but is a normal understairs space in the shame of an L.
ok it also has a door on it
a little similar to that, but its taller the door frame is made from metal, anyways im having, a little trouble figuring out how to create a negative pressure with out having to cut into my door or walls.
I am going to be getting a 5' carbon filter from ebay, im going to be funning the silver hose outside of my door on my growroom, so the door is going to be open, i could drill a few holes in the bottem left of the wall were the brown lines are on the pic below, into the cupbord, and leave the exhaust fan there. i need help just creating and understanding negative pressure.
sorry about the longish post and looking forward to the replys thank you very much.![Weed Leaf :leaf: :leaf:](/styles/smilies/weed.gif)
