Garden with Insight v1.0 Help: storage organ

A storage organ as used here is any part of the plant in which excess sugars are stored in order to be used for future growth (usually in biennial or perennial plants). In the first year biomass is added to the storage organ according to a linear equation based on the heat unit index. In the second year the heat unit index is reset to zero and some of the biomass from the storage organ is returned to the rest of the plant.
