Seed libraries and banks are critically important because the seeds are adapted to the local environment. Seed libraries have multiplied from only a handful a few years ago to as many as 300 located in towns across America today. Public libraries check out seeds to plant in your garden, asking only that you return harvested seeds for others to enjoy. Farmers can now “back up” their seeds in local seed banks, which are also becoming important educational resources to teach students about these issues.
Microgreens grow so fast that there’s little time for them to run into trouble. Commercial growers use large trays, but home gardeners can also use pretty coffee mugs or tofu boxes rescued from the recycling bin. Drainage holes in the container bottoms work well when growing beets or other slow-sprouting seeds, but are less important for fastgrowing sunflowers or wheat.
