Cleaning Chaff From Fresh Seed

Freshly harvested seed comes mixed with dry calyx material, tiny leaf bits and immature duds, and storing it like that invites mould. Rubbing the buds over a coarse screen, then gently blowing across a tray, separates most of the rubbish from the heavy viable seeds. A low tech winnowing method with a hair dryer on the cold setting is described on https://breederregularseeds.com and it works better than it sounds. Whatever floats in a glass of water afterwards is usually not worth keeping either.
