Amaranth, Chard, Beet, and Spinach Microgreens on Cheesecloth

I'm pretty much sold on using cheesecloth as a base for AG microgreens. The tiny red amaranth seeds have really taken hold, and have roots extending down through the cheesecloth. The microgreens have formed a solid mat, and can probably be harvested any time now (5th day).The Rainbow Sprinkles (beets and Swiss chard) are slower to germinate, but they are coming along. One of the Swiss chard pods in a fairly new Bounty garden turned out to be a dud, so I took three of the "Sprinkles" and put them in the pod. They're growing!Now I'm thinking that the Harvest Microgreens insert may be just the thing for starting hard-to-germinate seeds like spinach. With the paper towel method, only one of about a dozen of my spinach seeds germinated.I tried placing about half a dozen spinach seeds in the upper left corner of the Rainbow Sprinkles tray. With luck, the spinach seeds will germinate.

Today (2/4/22) I started growing some microgreens on cheesecloth in a Harvest Elite. The "cheesecloth method" is described in the YouTube video that campingcorgis mentioned in this post. (The link is right above the photo.)For no particular reason, I decided to try Amaranth and Swiss Chard. The cheesecloth successfully contains the tiny Amaranth seeds. However, it dries out between floodings--unlike felt or fiber mats--so I'm wondering whether that will make a difference in the way the microgreens develop.Something that I learned yesterday, is that it's unwise to dump AG microgreens water down a bathroom sink drain. The drain was running slowly, in part, because there were a couple of sprouts in the drain!
