I like that garden plan!
Those of us in apartments don't have that option without jumping through hoops that I'm usually too lazy for, so I favor less bacterial-friendly sunstrates that I can use for a much longer time before they end up adding to the landfill situation. I've mentioned to you eleswhere what my system is. But that's me. Because I have no real use for a constant supply of nitrogen-rich soil. For your own situation, this is way better!
Do you get any composting use out of your snake shavings as well?
