Nutrient density

Nutrient-dense crops begin with °Brix.

°Brix measures the sugar content of a plant's sap. The higher the refractometer reading, the healthier and stronger the plant: less pest pressure, less disease, better taste and storability.

Healthy °Brix ranges by crop
12°
Nutrient-dense

12 is the standard base reading for nutrient-dense crops. Better taste, longer storage, less pest, disease and weed pressure.

This is a general scale. Healthy ranges vary by crop.
