Uniform fruit size as an indicator of plant energy levels

Very healthy plants with an abundance of energy will have very uniform blossom size and fruit size in each cluster, or on each head, in the case of grain. The higher the degree of uniformity, the more energy a plant has. For those crops where we prune fruit or prune clusters, such as tomatoes and grapes, less fruit needs to be removed and yields can easily be increased once plants reach higher energy levels.

Higher energy levels become obvious when plants begin storing surplus energy in the form of lipids, and reach level three on the plant health pyramid.
