Sacha,
My tutor on these matters is a Galanthophile, and his recommendation
was specifically to buy snowdrop bulbs as damp packed, as this produced
yielded bulbs with the gratest energy. I bow to his knowledge as a
holder and propogator of many rare Glanthus.
For commercial mass sale I would agree that in the green sales are
vastly superior to buying prepack dry bulbs (a waste of time).
