Ok we do not care about the bottom of the cage. Not sure where you found that info or what general rule it was. But with these T5HO fixtures and bulbs literally you lose all uvb about 18 inches down from it. So they do not even penetrate 4 foot down. Your usable UVB focused distance for a 3 UVI is about 8-9 inches away from the bulb with the bulb going through screen. Once you hit about 14 inches your drastically reducing the UVI and lucky to see a 1 UVI level. Which honestly we want the UVB to fall off. They also need to be able to move in and out of it and move down further to get into different gradients of temp and humidity.38" from the bottom
Right at 11" from his basking spot. I will have my husband move it down another two inches when he gets home.
His shower curtain only covers the door and the side of his enclosure. I didn't get a full picture sorry. The top is uncovers as well as the other two sides are uncovered. The fog rolls to the bottom, and then out the other two sides. Should I move him another inch away from the wall to let it flow out more?
Will let the service door be uncovered
Are the other two sides all the way up to the wall though? If so there is not going to be full air flow. Make sure your not getting two much moisture build up on your walls. Fogging comes with its own issues for your house lol.
