I put mine together in April this year as it started to get quite cold over night and they have been breeding since, what I look for when breeding them is over night temps of around 10 to 15 degrees over night then I turn my heat off over night but I have heat of around 28 to 30 degrees from 7 am to 6 pm during the day, I then wait for the male to start pacing his viv when I see this i put him in with the female then it's a waiting game until both of them stop mating and they stop locking up then I wait to see if the female starts inverting on her back and then I put a nesting tub in with her then it's back to a waiting game again and I sit tight to wait for signs of things getting closer like prelay shedding which lets you know it shouldn't be to long before laying should occur that's just a bit of what I do to get them breeding it's worked for me so far hope it helps.
