You should really incubate those eggs on your own...Just kidding! I would give her a hot spot of 88. She'll most likely lay her eggs right on the heat. To keep the humidity up you could always use damp sphagnum moss. I personally would not use any mulch from Home Depot. They do not treat any of thier products for bugs and it could potentially be a problem. If you are going to use Cypress, get it from a pet supply place(just my opinion). Keep us posted BTW.
