The probe is for the TH-100 Digital Thermometer that I purchased from Reptile Basics. The probe is basically sitting in the substrate over the hot spot area. I'm not sure how you keep it from moving once the snake and hides are in place. I don't have a probe for the ambient side. I was just using a tempgun to measure (75ish on substrate).

The humidity was hovering around 50% but I haven't put in any water dishes yet or wet the substrate. I assume that number will increase when I do. I'm also wondering if I should just scrap the small bag of coco soft and go w/ a reptichip or something else to help conditions.
Thanks again for the response.
