Nice. Cool looking little pachy seedlings. I had some pachy sp seedlings at one point, but unfortunately I didn't have them in good pots and in a rain storm they overflowed and what didn't get lost had drowned by the time I got to them. They were still very tiny at the time.
What size are the pots on the left in the first pic? They look about 3"? Soon I'm going to have to repot my adenium babies that are currently in 1.5" & 2" cell trays, but haven't decided what size I should repot up to. I want to pot them up enough to be worth the work of repotting ~100 seedlings without overpotting them. I was figuring 4" pots? Maybe quart, but thought that might be too large. My seedlings are all about 3-5 months old and probably all between about 2" to 3" tall. They just seem to be getting cramped in their little cell trays.
