So the guy who sold me the QB boards told me that it's best to have the room temps at 82-85 with the LEDs. So how do most people heat their tents/rooms efficiently? If I am saving 50% on the wattage of the lights, but now have to run 60% extra electric as heat, I'm not really saving anything, I'm spending more. So what heat options that are efficient do people use? My tent is like 15X8. The digital ballasts and HID lights currently keep it around 75-81 in the winter time with no extra heat pumped in except at night when lights are off. Now I am looking at having to heat it with the lights on as well.
