I use the Eco-earth(coconut), never though of mixing it like Kris does? Sounds like a good idea. The coconut takes a lot of mist and water to get the consistency right so it is not so sticky. That's why so members don't like it.
I've had great success with it in regards to easy clean up, long lasting and humidity control.
I may try the mix, next time when it comes time for a complete change.
