Metrics¶
Metrics are broken down into three topics: Air, Light, and Water. Each metric contains a min and max acceptable value. The smaller the difference between the min and max of a metric, the more strictly it should be regulated. The absence of a metric should indicate that the metric should not be tracked. If a certain metric is supposed to not appear, it should be explicitly defined with a min and max of zero.

Light¶
Light metrics are separated into one or more bands. A band is defined as an upper and lower wavelength (nanometers) within the electromagnetic spectrum. Within a band a light intensity is defined with the usual min and max values. Light intensity is represented in PPFD (µmol/m2/s)
