Questions about my grow box LED Grow Box System | Complete Plant Grow Kit I ordered this and i've been reading a lot about LED's and about their flowering capabilities. I was wondering if I should place additional CFL or HPS lighting in this box for flowering. However, if i were to get an HPS, how would i go about ventilation in this box? Would i even need it?
