I tried it once. For my location- New Jersey, it just made too much humidity. It took about two weeks to get the humidity going below 75 and that is after we removed scoops of it and blow-dried it. Then it held perfect humidity for a few weeks and I thought OK wonderful, but after that it dried out bone-dry and really needed a thorough soaking to bring the humidity up again. I did not like how wet it had to be to have my humidity at 50-60 much less how wet it had to be for 70%. Also, I was using the compressed brick and even after soaking it was rough on my python's scutes and the dust got inbetween them. After all of that I decided to switch to aspen which holds humidity well for my area.
