Microgreen Seed Density Calculator
We recommend using these values as a starting point, and then experimenting to find what works best for you. Varieties with a * after them are based on the seed densities used by our co-founder Garrett Corwin at his farm Piedmont Microgreens. You can read more in our yield and sow density cheatsheet.
