Hi,
I thought the repti-temp was an on/off thermostat? Does that mean you have a flashing bulb or does the one you have not give off any visible light?
If it gives off no light then I would leave it on 24/7 - other wise I would probably use a dimmer switch to control the lamp instead as flashing lights can cause stress in the animals and family around it.![]()
As to the insulation Mine is simply fixed onto the outside of the glass tank with good heavy duct tape.
The tinfoil will help a little but it really isnt very good at keeping temperatures up in the same way that cork or polystyrene is.
