Horticulture systems and methods including an air handling rack system comprising frame supply and return plenums, an input diffusion assembly physically supported by and fluidically coupled to the frame supply plenum, and a plant support tray assembly physically supported by and fluidically coupled to the frame return plenum. The input diffusion assembly is configured to direct a supply airflow flowing through the frame supply plenum downwardly from an underside thereof. The plant support tray assembly is positioned below the at least one input diffusion assembly to form an environmental cultivation chamber therebetween. The rack system is configured to direct the supply airflow through the environmental cultivation chamber from the input diffusion assembly to the plant support tray assembly past one or more plants positioned on a support side of the plant support tray assembly and into the frame return plenum as a return airflow.
