Lightingg???

im using 4 1000 watt lights.. is it nessescary to vent threw them? is there any other way to keep lights cool from over heating besides venting threw them?

One should start small and learn to walk before attempting a marathon.

have you used "1" 1000w light yet, let alone 4. how big is your grow area that you need that much? how many plants? what type of ventilation? hydro or soil? those are gonna put off alota heat. seriously
