What kind of biochar do you use and where do you get it? I have just started reading about it.Interested to hear people's thoughts...as the OP mentioned, it's a topic where there are lots of opinions but not a lot of first hand experience out there. I'd be interested to hear if people purchase coffee bedding or reuse their own coffee grinds, get them from coffee shops, etc.
When I have it, I add biochar to my bedding. It helps absorb moisture and excess ammonia.
