Hello, I live in Minnesota where the warmth is unpredictable. I am a newbie with a 4 year old russian tortoise. I have had him for 4 days now, and I want to be sure I am doing everything right. I was told to use a UVA non-coiled bulb, but I have read conflicting reports of using a UVB. Do you use both and for how many hours a day? Also, is it normal for it to hide in his half log in the evening hours even when his light is on? I really need to soak him, but he is hiding and I don't think I should move his log to get him. I think he should wake up on his own. On the other hand, I need to soak him. The last time I soaked him was 2 days ago. Any help would be much appreciated!
