I have a few microgreens again - and it looks like we'll always start the indoor greens season with micros, as long as I have seed surplus from what I saved.
This time it's radish, arugula and kale. The radish seed I saved just for this purpose because my mom liked those micros the best - but seed yield wasn't great just enough for one tray.
Oakley, thanks for mentioning the ferts. My delivery to mom got delayed because she had dental surgery and didn't want to deal with them. I notice that once the cots are fully out (about 8-10 days) they are really slow to push out the first leaf at the high density. Probably too late to give ferts now as I think she's close to ready for them. But will keep it in mind for next.
I used a deeper tray and gave them a full inch of compost this time, but didn't really affect that slowing of growth at about 10 days.
