Awesome thanks, I tried that with a cfl and didnt realize the difference. I think Il try that with the extract thru bottom vent tech. Then the grow tent heater if needed but the ceramic IR I read it can scortch tent fabric and plants and to use probes everywhere on controllers. Just seems like a last resort.
As for spectrum, I was just pointing the cfl away from the plants with those clip on lamps or clamp lamp. So it was just shining in a corner for heat but didnt do much. I wonder if one or two is enough maybe three. Its a 5x3 thats 6 foot tall.
