Then depending what I am going to plant will decide what pot or cells are going to go in the tray. This tray will hold 18 - 3" peat pots.

Another is it will hold cell packs. I like the cell packs when you want more plants. I like ones that you can tear off. They come in different sized 4 cell, 6 cells, 12 cells but they are tough. This way you dont have to take the whole tray to plant or you can rip some off and give to friends, neighbors etc. Just make sure you get the right sizes for the trays.
