Only if the CFM doesn't match within 10%. The airflow design was made to induce positive pressure to keep dust out (since I don't have to worry about keeping smell in.)
khyberkitsune Reviewed by khyberkitsune on . 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?
