Overwintering is not as simple as it sounds. I do agree with Sandy about reducing temperatures at night and also 30c seems a a little high as a background temperature every day. I would suggest 23c as a more suitable daytime temperature for most Mediterranean tortoises. This should encourage them to bask and provided visual light levels are sufficient it should increase activity. If your tortoises find they need to bask to achieve optimum temperature there is more chance of them choosing the basking site for nesting, giving you the opportunity to provide sufficient depth of soil in this area.. The best depth of soil for nesting in my opinion is a minimum of the tortoises SCL.
