Lettuce is something that is cold hardy and can be grown over the winter. All you need is a bag of potting soil, a packet of seeds, and a plastic container box. The bottom of the container is used as a green house if you are in a cold climate area and need your greens to be protected from the harsh winter.
This is something that most people can try where ever they are!! Here is the video by Roots and Refuge called “Grow Salad Greens All Winter For Less Than 20 Dollars”. I hope you enjoy this video.
