I use this ground for my corn snakes and my black Mexican Kingsnake. The blacks I hardly see since he loves it, in the (very slight, pleasant smelling) earth to bury. One can well put plants in the ground, feces can be very well located and the humidity can be controlled perfectly.
Even my corn snakes dig very happy in this ground. There are no problems with mold, etc., also dried remains of ground nice and light and grave capable (without clumping).
The only drawback: The Abpackungsgröße. With 8.8 liters I can not get far in my big terrariums.
