Sand, Silt, and clay are terms used to describe SIZE of particles and not
composition.

On bamboodirect, they suggest using Dyna-gro Pro-TeKt to supply the
plant with silica. Is there another product that will work the same?

They only recommend it for container-grown plants in certain
proprietary growth mediums.

Unlike most other plants, grasses metabolise silica, and a lot of it.
Sand, silt and clay are three of the four main components of soil, the
fourth being organic matter. Sand is largely silica (but possibly not
so easily available for metabolism); clay is hydrated silicate rock,
(and probably therefore provides silica most easily available for
metabolism, in general); silt is intermediate between sand and clay.
So if you are are growing bamboo in a balanced soil in the ground, or
in a soil-based growth medium, I think it has plenty of silica
available.
