Even though we show that you can easily grow a new tray of microgreens on reused microgreen soil, we still do not recommend it.

The chance for disease is too great, and it takes a bit of time to prepare the trays for planting. We'd rather throw the old soil in the compost heap and plant a new tray of microgreens on fresh soil.

Fresh soil leads to fresh microgreens. 

This is the reason we use soil over planting on microgreen mats.
