I had asked her when I bought the power supply, why can't I think of the name of it lol, I asked her if it would be a problem to run a 400w bulb at 250w and that was her reply, I guess not running at 400 causes damage of some sort.
I'm blowing cold air in, like 55-65f, but with the tent door closed, top accessory holes open, at 400 I think the light is just too strong, cause it's still staying at 89f.
I guess I will turn it down and try and get the heat to at most 80f, but with no thermostat it's kinda tough to control temp.
