Hi again glad you made it from Profile posts to the Introductions. I think 104 is probably too high for a Russian, but this is the caresheet you need to follow to make sure you get the temps and living conditions right.
I chose the title of this care sheet very carefully. Are there other ways to raise babies and care for adults? Yes. Yes there are, but those ways are not as good. What follows is the BEST way, according to 30 years of research and experimentation with hundreds of babies of many species. What is...
Temps must be read with a reliable thermometer. When deciding on the height lamps, I use a stone or upturned bowl about the same height as my tort under basking bulbs/che to check the temps on the surface so that I know how hot it is on his shell. If you hang the bulbs you can adjust the temp by raising or lowering them.
In your profile post you mentioned that you thought your tort has shell rot but I'm wondering if the lamp is burning him. Please post some photos of it so that you can get advice on what it is and how to treat it. If you post pics of his enclosure and lamps you'll also get advice on making sure is enclosure is as safe as possible for him.
I think Tom's superb care guide suggests 95-100 in the basking zone, but 104 is probably acceptable, so long as the tort is properly soaked and hydrated and the temps in the rest of the enclosure allow it to cool down as it wishes.
Unless there's a specific reason for it, and there are redundancies built in, I think a 104F basking spot is too hot for an indoor enclosure. There is significantly less margin for error with heat/hot temperatures.
