I went looking for sieve analyses of different producers of "light aggregate".
There seem to be mostly "too big" and "too fine" products.
Hydrock Medium might be interesting but I could find the size range.
Haydite Greenhouse Blend straddles the right size, but aren't ¼" too big and 1/16 too small?
Haydite Nursery Blend seems close but too coarse, primarily ⅛" to 3/8" particles sizes

Hydrocks Fines 0 - ⅛"
Medium?
Hydrocks Coarse 3/16 - 5/8

Norlite see photo -
Intermediate is 62.5% bigger than 1/4"
Fine is 60% passing 16 mesh.
