Subsitute for Turface in Gritty Mix
I cannot find any local suppliers of Turface, and shipping costs are ridiculous. Same for clay pellets (Hydroton) and expanded shale.
So is there anything I can use instead? The only thing I could think of is one part of good quality potting soil (e.g. Black Gold) with added pumice, to go along with one part each of fine bark and grit.
