I'm thinking of using Reptichip as one of my choice substrate but heard it often compared to Grow!t and stated that it was exactly the same thing and functions just as well. I've been seeing a few reptile keepers using Grow!t instead of Reptichip and was wondering if anyone else had any experience with it? How does it compare to Reptichip or other substrate you've used? How is it different and how is it similar?
