Good point Flowerbug-- I didn't think of that. So far I am using seeds that I have an abundance of. I am going to be up to my eye balls in Alpine Poblano seedlings, because they are germinating like crazy with this method.
Also, the first cucumbers are forming on my Bushcrop plants. Exciting!
@Branching Out If we think about the first two stages we grow microgreens -
Stage 1 / Germination: Warmth and Moist are necessary, Substrates and Light are not necessary
Stage 2 / Cotyledons: Warmth, Moist, Light are necessary, Substrates is still not necessary
Maybe sowing most of the vegetable seeds in the way we grow microgreens and then prick them out is practical and can save a lot of troubles and space.
I pricked out and transplanted some strong seedlings from the previous batch of microgreens in the module trays, and the result is very satisfying. Therefore, I ordered some silicone mat and tried such a setting this morning. If it works well, then both microgreens and some veggies can be done with this method, imo.
The seeds I used in this experiment is basil from the microgreen seeds I have, and I can easily put this small cream cheese container on the window sill (with heat from the below, our radiators are always below the window). As basil and lettuce seeds are much more sensitive and prone to rotting in an overly wet condition, I misted the seeds lightly instead of soaking them in the water.
Silicone mat are easy to handle, clean, and reuse. When I saw people use it to grow microgreens, I immediately thought about this might be a good solution for seed germination.
