I use both small glass bowls (8-12-18 ounces, buy in packs of 4 or 6 or 8 depending on size) and paper bags, and like them both for different reasons. The bowls are stackable, heavy, even around me they seem unlikely to break very often, and the only drawback is my husband runs off with them to sort electronic parts. I use the bowls for wet seeds that need soaking. Dry seeds go into paper bags, label with a marker and park somewhere to dry until being cleaned. If I fold 2X and staple the top shut, I do not have to worry about aforementioned spouse or self knocking them over, etc. Speaking of seeds, despite a very cool summer here on the PNW coast, my Dierama pulcherrima plants managed to set seed. I know this is not a geophyte, but if anyone is interested, let me know and I can send some seeds on to others. Kathleen PNW coast, z 7-8-9, depending on the winter
