A vertical farming system comprising:

• 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 including a fan mounted to the platform, the fan being configured to generate an airflow through the ventilation space;
• and
• a support structure configured to support the plurality of support units in a vertically spaced arrangement.
