Anyone else using this mix?
It is supposed to give balanced silicon and pH.
The mix they use is for all their studies is:
75% peat
13% vermiculite
12% rice hulls
0.7kg/m3 wetting agent
1kg/m3 wollastonite (equals 1g/L)
1.3kg/m3 hydrated lime
Here is a publication documenting performance of the USU mix.

I had never heard of Wollastonite before now!
