I am getting ready to order some catts. The vendor I am ordering from grows these in Charcoal nothing else in the mix. Does anyone have experience growing in this medium?
I haven't heard of straight charcoal, however that does not mean anything. I use approx. 1/4 charcoal in my mix of bark, c. nut husk, perlite. and my cats. seem to like it. Good luck with your new ones.
