humidity seems to be ok, i've coverd the screen top w/ foil and i have a 125w heat lamp on one side.

i have a small uth under the hidebox. it doesn't get real hot but will keep her warm at night(the tank is in my oldest son's room and a nighttime bulb will disturb his sleep). is it ok for the uth to be under the hidebox or do i need one that will fit across most of the bottom?

i also just bought a 50qt plastic tote (26.7x15.8x10.8)to toy around with. i have some ?s about setting this up as her house...

there are 2 decent lock tabs on the ends but what could i use to keep it securely shut?

how do i heat it? a uth under the whole thing? how would i incorporate a heat lamp or do i need it?
