clarification with ingredients in Al's gritty mix
Pine or fir bark in 1/8 - 3/8" size (no fines)
Screened Turface MVP
Crushed granite (Gran-I-Grit, in grower size) or #2 cherrystone
First off what is 'screened turface MVP'; I've never heard of it and I'm guessing that what is listed in the mix is an abbreviation.
Also what is '#2 cherrystone'. In reference to the granite, where can you find it, and does it come crushed, or do you have to crush it?
This is a really stupid question, but is gypsum the same as lime, or is it different. If so, how?
If so, what's the easiest method to crush it? How fine does it have to be (coarse, medium, small, a powder.....)
