Microgreens should be in your winter plans.
They can be grown indoors so quickly that you won't kill them before they are ready to eat.
Since they can be grown inside, it doesn't matter if you live in a high-rise or a cold zone.
They are nutritious and provide a connection to gardening that can keep you sane.
I've written about them before, so check out the more extensive article: Microgreens! Vegetables in 7 Days!
The YouTube video is very popular too: Grow Microgreens! Vegetables In 7 Days!
Get some groceries in 7 days! Well, 10-14 days if you keep them cold.
Really, you won't believe how much better you feel when you eat fresh, home-grown vegetables in the middle of winter.
