These came up fast, one in under two days and two in under three days. Like all my Night Owls these are very slender and delicate, and one has the longest stem I've seen on a normally grown bean at four inches, the others are more normal but all three are very very thin and require help to stay up. They should be able to hold themselves up in a few more days.
This is the first time that I have soaked and squeezed the plugs, normally I just soak them, but I expelled the waste down the drain and re soaked and I repeated this till I was getting a run off of about 250ppm.
