Right now I have my 2 month old bp in a 20gal long tank, I know day and night cycles are important for them, and so I have a day and night lamp that I switch out. But I'm in the Army and I go to the field a lot, so I have my wife do it when I can't. I was thinking, to make it easier on my wife, can I keep the black night heat bulb on 24/7 as long as I open the shades to keep the natural light cycle going and so she doesn't have to swap lamps?
