These are seed starter pots designed to fit inside the 1020 Bootstrap Farmer Extra Strength Microgreen Trays. They fix 3 x 5 for a total of 15 starting pots per 1020 tray. The bottom is removable so when you're ready you can push the entire plant plug up from the bottom.
The compactor can be used to compact the soil in the pot, or to make a small hole to drop the seed in.
