Hey guys im starting my first grow. yay for me right.lol but i have a question regarding ventilation. Ok So i wanna setup in this closet i have in my back room, its an open closet with the type shudder doors. but i pick the back room cus the ceiling opens up into my attic ( ceiling of the room not the closet) and i have a big exgust fan up there that we use every once in a while, that i thought could help move things around. I guess the people lived her before us did it for there kids, when u look a one of the walls in the room it looks like a ledge and the have a ladder u can climb up and go thru the rest of the attic. So its a big space im working with, but im only trying to grow 2-4 personal plants thats all in the closet of that room. so does any one have any tips on how i should setup my ventilation?
