You inspired me to pick up some plug trays with smaller cells than I've ever used before - 200 square cells with 1" tops, 2" deep. That's a 10x20 array of cells.
If I learn to plant out from them before seedlings get root-bound, maybe some day I'll try a 12x24 tray with 288 cells!
How many days after emergence can you leave a lettuce seedling in a cell that small, before it's root bound? 3/4" square?
