Hi, i am building a cabinet grow so i can try to grow some. The size is 91 cm x 68 cm x 37 cm (36" Hight X 26" Wide X 15" deep). My questions are: how much lights do i need? Can i get away with 3x 24W CFL? Venting, how much do i need? I have 4 120mm pc fans. How many plants should i try? Autoflowers or normal female?
