best substrate for box turtles

[ReptileHQ]

my point is....it's basically all the same....but include some sand.....and hay provides nothing in the way of micro-climate opportunities(too dry). I would definitely exclude hay from any Terrepene enclosure....much better choices to be used....

My mix....organic potting soil 30%
peat moss 30%
sand 20%
sphagnum moss 20%

I have experimented over the years with substrate and found this mix to be most effective. I have kept box turtles for 20 years and bred them for 15 years.
