Hi all, I just recently purchased a 3x3x6.5ft grow tent and I need help deciding lighting and ventilation. I'm thinking 4 plants in soil. I'm putting the tent in my basement, which stays pretty cool. I have questions about my lighting.. Should I go HID or LED? I was thinking 400w HPS/MH Cooltube, but I also came across the idea of LEDs. I'm not exactly sure how the wattage goes with LEDs.. But from what little research I did, people say they stay cooler and preform better than HIDs. If someone could please shed some information on me or toss me some suggestions I'd appreciate it. Also, I'm thinking passive intake with a inline exhaust. Any tips?
