Refractometer (Brix)


A refractometer is a prism/type tool where light is refracted through the plant sap juices. The more "content" in the sap, the higher the "Brix" reading will be.​

A plant's Brix reading directly correlates with its general health, stress resistance ability, and nutritional density.
