The critical ones that are immediately necessary for survival are #1 and 2. For number 3, any additional light source will do. Just a cheap lamp with an LED bulb from another room, or if the blinds are open during the day will help.Hello Tom how are you doing today? I can't get all of those different lights right now, ( I know Fred needs them but what do I absolutely need right now? I got the basking light.
You don't need number four if you can get the tortoise outside in a safe enclosure a few times per week for some sunshine for an hour. Its okay of the tortoise hides in the shade because of the intense AZ heat. Access to sun will do it. Try to sun in the morning, before it gets too hot. Make sure your calcium supplement has D3 in it and that will help too.
