Are Fluorescent lights (instead of RHPs ) sufficient to keep the ambient temps up enough if you use belly heat? Someone in another thread suggested foregoing RHPs entirely (because they use a good bit of power) and using fluorescent lights to keep up the daytime ambient temps, and an LED light string to provide sufficient ambient heat in the night time (?). Also, now difficult is it to install RHPs? Does AP pre-install them on request? I didn't see any related steps in the thread.....(forgive me if they're there...)
