I've found this video http://www.youtube.com/watch?v=qB0a7...eature=related which shows a guys terrariums and I am really impressed with the dry, cracked desert type substrate he has in most of the tanks (starting with tank #2/P. murinus onward)
Anyone know what that substrate is? I'm supposing a clay of some sort.
I'm softening a sample from a sack of all natural kitty litter (bentonite clay) in water overnight to experiment with sculpting & drying in hopes of getting close to this guys work. I know it's supposed to sculpt and grow moss well in frog tanks but it also cracks when it dries, which is exactly what I want in a desert tank and can't achieve with dry peat or coir. Anyone else done a kitty litter tank yet, moist tropical or dry desert? Any hints to working with it? Can I rapidly dry "layers" of clay strata in my oven at low temp?
