Dry-stall vs Horticultural pumice ... was algae and moss in seedling pots

Hi Ken,

I have been using Dry-Stall for a long while and usually get really good
results from it. For a few years the grains were pretty small and even. In
the last year, they seem to have switched to ones that have a good mix of
sizes, even the fine powdery size mixed in, not unlike horticultural
pumice. Some people don't like this dust but I don't mind and my bulbs
don't seem to mind either.

Both Dry-Stall and the common horticultural pumice in California is mine by
a single company. I think the only difference between the two is that one
is sifted better and the other one has different marketing.
