>> AND, I transplant very early on.
You're probably smart, but I'm clumsy and I get nervous when I see a tiny white thread that's the entire root. Other than WS, you use plug trays with small cells, or "broadcast" seeds on flats?
I agree that most of the bark in some "mulch" and most "nugget" products are much too coarse for seed starting. I use the finer stuff screened from each bag for seeds, the next bigger cut for containers (like 5-gallon pots) and the biggest c hunks for mulch outdoors.
But it sounds like you have a system that works for you, and with lots of trays. I'm still learning how to kill fewer seedlings.
