The Seed Density Calculator Course gives you access to the calculators I have created that provide you with either the number of grams or teaspoons of seed you need for any size microgreen tray.  Over 30 different microgreen varieties are included in the calculators. 

The course has a video that shows you how to calculate the size of the planting area of your microgreen trays and how to adjust the calculator to give you the correct amount of seed to use.

The calculators are web-based only. They are not downloadable. 

There is a calculator that provides how much weight of seed to use in grams. As well as another calculator that will give you the volume in either teaspoons, tablespoons or cups depending on the seed size. 

Because I know it can be a burden to access the calculators everytime you want to use them I have created downloadable sheets where you can write down the weight or volume of seed you need for your tray sizes and store these sheets where you can access them quickly.
