Abstract: A vertical farming system includes: a plurality of grow trays for receiving a growth medium for germinating, propagating and/or growing living organisms, each grow tray including a bottom tray surface; a plurality of support units, each support unit including a single platform including+ a top platform surface for supporting the bottom tray surface of a grow tray from below, wherein each bottom tray surface and/or each top platform surface are configured such that when a grow tray is supported on top of a support unit, a ventilation space is defined between the bottom tray surface and the top platform surface. Each support unit includes a fan mounted to the platform, the fan being configured to generate an airflow through the ventilation space. A support structure supports the plurality of support units in a vertically spaced arrangement.

Abstract: A grow tray including a perimeter wall and a base. The base includes an irrigation opening extending through the base for allowing fluid to enter and leave the grow tray. The base is couplable to a conduit to allow fluid communication between the conduit and the base via the irrigation opening.
