how much heat does a 400 watt hps generate and how much heat does a 250 watt HPS generate is it possible to run them in a clost with just a fan blowing on the bulb the closet is 2X7X7 roughly also would a 250 watt be enough light for like 10 plants?
im looking on insidesun.com and i was wondering if there is a difference between hortilux or the bulb that this kit comes with it doesnt specify what kind of bulb it comes with but the hortilux is like a 60$ upgrade so is it worth it or not?
