Thanks! I didn't realize they could last that long in seedling trays.
I've only started Bok Choy in trays for fall once. If I recall, after three weeks they were trying to climb out of their cells and transplant themselves.
But I had started them in prop trays outside in full sun, in the long-day part of summer. We have cool summers! I figure that let them grow faster than any indoor seedling could.
