Michelle, how do you set up your winter radish and buckwheat? Are you growing them as shoots and eating them as soon as they sprout, or are you growing microgreens to the point where they have a couple true leaves and need some light?
My radishes I grow as sprouts in a jar and has greens in a black pot.
I started growing them as larger greens in large black pots two summers ago when we moved and did not have the space for a regular garden.
It is easy to grow them quite large till the real leaves start to grow. This whole process takes two weeks. They are so quick to get to a very large size that there is no comparison with growing lettuce for volume and speed. The
After this period I consider them oversized. If they are oversized then I cut them and throw them in the freezer as it is the quickest way to deal with my surpluses.
Out of one pot, I can get enough greens to fill a large bowl. Usually I divide the greens into 3 or 4 days harvest days as I mix them with lettuce and other greens or sprouts that I have to make a nice salade.
Now last winter, I did not grow them in large black pots. I grew them in bowls according to this book. It is a great method.

But after two summers growing them in large pots and having them grow to quite large leaves compared to growing them in the bowls, this winter I am expermenting of growing them in the pots since they can grow much larger before they get the new leaves. But to grow them in pots, since it takes much more space like a greenhouse, or dedicated location, then for most people the method of doing them in bowls might work much better since you need a lot less space indoors and most people do not have a greenhouse or space they can have large pots.
Radish leaves are edible, but since they get prickly, most people do not, althought if I have some prickly radish greens, I will cut it in small pieces and add them to soups and then there is no prickly feeling.
For our needs, I do two black pots each week to get sufficient radish greens, but we still have some lettuce that I grew in pots in the late summer that I mix with the radish greens. Now I will also do buckwheat greens this way. They are often referred to as buckwheat lettuce. If the stems get thick, then instead of adding the stems to the salad, I chop the stems to add to soups or stirfries and the leaves I keep for salads.
I also continue to grow radish sprouts in jars throught the winter. They are nice in sandwiches or I'll add them to soups.
My buckwheat seeds have shells so I cannot sprout them as there is no way to separate the shells from the greens. So I grow them either in bowls or pots.
This winter I will probably buy some sunflower seeds to grow them as greens. I currently only have already shelled sunflower seeds and they do not grow right as shoots. So for now I just sprout my sunflower seeds and add them to salads & natural peanut butter as an extra crunch.
