Dean, I think it will be a little difficult to get these plants to stir-fry size in (what?) 72 cells per flat. So, that would be maybe 150-200 plants in a little more than a square foot? Maybe wait until all of them would make a nice addition to a salad with a friend but you couldn't wait much longer than that.

We eat bok choy beginning when the entire plant is only about the size of my thumb and continue until just the flowering stalk is about the size of my thumb or bigger. (At that point, we are eating the stalk and flowers not the leaves.)

I think if you have sufficient seed, harvesting even the smallest size would make sense.

I think they are 2" cells actually, but I get the point. So basically, the cells need to be thinned to one seedling as soon as they germinate? Guess I better get to snipping.

I don't know if sowing a bunch of seeds in a large pot (20"?) indoors would make any sense to be able to get bigger seedlings to eat for the winter. I was going to rig up a straw bale cold frame outside too, maybe that would work. Or maybe, I'll look into sprouts.

These Asian greens are hardy! And, can even survive sub-zero temperatures (altho' not well). Of course, surviving and being palatable are 2 different things.

Sproutpeople have quite a few brassica seeds. Some of these are tiny seeds so the price for those goes really ^UP^!!
