I have decided to build a grow box and put it in a closet in my spare bedroom. The closet is 5' (Deep) x 4.5' (Wide) x 9' (Tall). The box I am putting in will have 2 sides with 3 chambers. The box will be 3.5' (Deep) x 4.5' (Wide) x 6' (Tall). I am going to make two main chambers, one for veg (3.5' Deep x 1.5' Wide x 6' Tall) and one for flowering (3.5' Deep x 3' Wide x 6' Tall). The veg chamber will be two smaller chambers, one being up top for clones 1.5' Wide x 2' Tall. The bottom part of that chamber will be for mothers and will be 1.5' Wide x 4' Tall. I want to end up flowering like 3-4 plants at a time. I am planning to use a passive intake active exhaust for ventilation with an inline duct fan like Inductor 6 In. In-Line Duct Booster Fan - DB206 at The Home Depot used for the exhaust. I just need to figure out how to wire that fan so I can just plug it into an outlet. I am planning to build the box out of wood using thin particle board or similar for the walls and lining it with mylar sheeting. I am growing Joey Weed Blueberry and Cindy 99 x AK47. Here is the layout: What does everyone think? Any ideas? Suggestions?
