I passed your post on to Moggy. She said to get some sprouting seeds if you can.
I know from past experience if you want sprouting seeds through organic farmers you tell them you want growing seeds. Hopefully you can find them locally. Put them in food type air tight containers take the air out. I used Israel’s suggestion back when with dry ice. Put it in the bottom of a food grade bucked covered it on both sides with paper plates waited till a match went out when the slightly open lid in the bucket and sealed it.
