Final Update: 4/20/2022
I decided to repot the seedlings in 6" & 8" hanging pots. Finished the work yesterday and here are a couple of pictures showing the results -
Stats: Shown - 24-8" pots and 3-6" pots. Plus 4-8" pots and several pots of seedlings rehomed. With 3 plants per 8" pot and 2 plants per 6" pot + seedlings rehomed = 90+ plants total.
Now I'm looking forward to the children growing up and showing their personalities. It's been a fun and rewarding project.
