Forgot to mention that the bowls are only 5 inches across. The bag of milled sphagnum came from Lilian Maroushek (the 90 year old). I am guessing it is at least 15 years old. BTW, the lily books she recently gave me are a set of NALS Yearbooks, dating from 1949 through 1988, Two or three missing in every decade, but what a jackpot!

Regarding builder's sand and the variable size grains and pebbles, Lorn spoke of aggregate grains too fine to be of good use. My thoughts exactly. That in builder's sand there is basically fine grains and pebbles with very little mid sized aggregate, makes it a difficult soil amendment for gardeners to use properly. The alpine pants that I grow require far better drainage than any lily. However, while the larger pebbles are not particularly amenable to seed growing, they are integral in providing a more continuous capillary flow
downward, and thus contribute to a better draining medium. The mineral based component of amendments in my soils is play sand (for the same reason as Lorn) for lilies, with the addition of various size chic grits for alpines.
So, Jo Ann, builder's sand is not the same as your stone sand. Turkey grit would be the #4 Grit here:
Sand with polymer binders, as far as I know, is not used as a base underlying pavers as a general rule. There are exceptions, and Jo Ann's nicely done walks are good examples. This combination costs four to eight times times that of sand, so is normally used as the filler aggregate
between pavers, be they stone or cement. There are different types of sand/polymer mixes. Some harden almost like cement, others merely lock the particles in place, but can be picked at, with a fork, for example.
