My Leopard Tortoise is 2 years old and I live in Michigan. I have made her a indoor open enclosure and need help with a few questions. I have a 250 watt ceramic bulb for heat Hanging above the substrate about 1 foot away from it. I have a uvb light hanging about 2 feet away from the heat bulb. I am wondering about humidity without a cover. I have some live plants in it and have dandelion seeds and grass seed planted.
