How Humid Should My Leopard Gecko Tank Be Questions About Female Leopard Gecko Egg Laying?

Questions about female leopard gecko egg laying? - how humid should my leopard gecko tank be

My female leopard gecko is to lay eggs at any time, I have a box for him in the tank is filled with garden soil. Are there any favorite places in the tank which should keep the box (it is 40 gallons and has) plenty of hot and cold? What must I hold the field was wet and damp as they think of him? When the eggs hatch, how to manage them? And how can an incubator house, how can I keep up? All or some of the questions would be a great help!

Thank you,

Kevin
