My friends has a attic space that can only be accessed from his room and we have chosen to grow up there. there are 2 air vents in the attic that go straight out side .. i was thinking of hooking this up to a grow box so most the smell goes outside.. ( this is what i should do right..) we want 2 grow as much as possible without it smelling downstairs so how many plants do you think we could grow.. ( i was thinking 6? )also what lights will we need to purchase ( can i buy lights from home depot that will work or do i need to buy them online? ) i also was wondering how long the process would take and how much weight 6 successful plants could make.. i appreciated any help or tips you can give me. and what strains grow the easiest and fastest.. ( im clueless about this ) THANKS!!
