How long should a uvb lamp be on for per day? I currently have a heat lamp and uvb bulb combined but I’m debating getting them separate, how long would it have to be on for per day? Thank you! ?
Depends on the amount of UV output. There are two general strategies. Lower levels can be run all day, or you can run higher levels of UV for 3-4 hours mid day, which simulates what happens outside.
