I store my sprouting seeds in these wide-mouth plastic containers from Walmart. They come in two sizes and have a screw-top lid.I made labels for my containers with my label maker. The type of seed in on the front. On the back are instructions for how much seed to use in my sprouting tray (1/4 cup of mung bean seeds).
These containers keep my seeds organized and I can easily see when I need to replenish my seed stock.
