I am now the proud owner of two 1 year old Herhanns.  We have made a table 4ft by 18" with a  3ft uvb strip and a 100 watt spot bulb both 10" above the highest point of the 50/50 sand and soil, we have a water bowl and slates, as well as a little sheltered house part. The temp is 30 near the basking spot with a slate under it. We put them it on Saturday and they seemed really happy for the first few hours then they buried themselves. 

We are waking them up at the moment to feed them etc, as we are scared because they are not waking up. Once they have eaten they stay awake for about 20 minutes before burying themselves again. Are we just being impatient? They have come from a viv where they had meadow hay and that fake cat litter type stuff. I am concerned about it catching fire so haven't put any in. Is this normal?  Do we need to increase the heat source? We leave it on 24hrs with the uvb on timer.  

Sorry for so many questions - we had thought we had researched and were set up to go but now I am worried that we are doing it wrong and I really want them to be happy and healthy.

The setup you have is fine, I assume the 30C is measured at tort. level.

Does the spot bulb have a dome reflector, to 'aim' the heat over a fairly large 

area ?

As they had keen kept in a vivarium, it will take quite some time for them to acclimatise, so just put them around the basking spot several times a day, as you are doing.

There is no need to leave the heat or light on at night.

Keep us informed,

Tom

Thank you very much for your help, yes the temp is at tort height and have a dome. We also have a nice area away from the lights where they like to dig in.

Glad we seem to be doing everything right, hopefully they'll settle in soon
