Phenotypic horticulture systems and methods

A horticulture system, comprising:

• an air handling first rack system comprising:
• at least one frame supply plenum extending upwardly from a bottom side of the first rack system;
• at least one frame return plenum extending upwardly from the bottom side of the first rack system;
• at least one input diffusion assembly physically supported by and fluidically coupled to the at least one frame supply plenum, the at least one input diffusion assembly being configured to direct a supply airflow flowing through the at least one frame supply plenum downwardly from an underside thereof;
• at least one plant support tray assembly physically supported by and fluidically coupled to the at least one frame return plenum, the at least one plant support tray assembly being positioned below the at least one input diffusion assembly to form at least one environmental cultivation chamber therebetween;
• and
• a plurality of panels that collectively extend about a periphery of at least a portion of the first environmental cultivation chamber to substantially enclose the first environmental cultivation chamber, and
• wherein the first rack system is configured to direct the supply airflow through the at least one environmental cultivation chamber from the at least one input diffusion assembly to the at least one plant support tray assembly past at least one plant positioned on a support side of the at least one plant support tray assembly and into the at least one frame return plenum as a return airflow.
