I am looking to upgrade my beardie's terrarium from her current one, which is 36x18x12 (LxWxH). She is 2.5 years old and 15" from head to tail. A couple of options I saw were available were 36x24x18 and 36x18x24. The main question I had for either one would be how I setup heating and lighting for the tank. Currently, I have a 22" T5-HO 10.0 on top of the screen of her current tank and a 100 watt basking bulb on a dimmer to make sure the basking spot is around 105-110. How far away from her basking area would I need to setup the T5-HO, and how can I setup the basking bulb nearby? Note that I would want to keep the screen on the top since she is a climber. If any other information is needed, please let me know and thank you!
