Modular plant growing systems

A pot module for a modular plant growing system, comprising:

• a) a pot body having a base, a top vertically opposite the base, and at least one cavity open to the top for receiving a plant growing medium;
• b) a control system including at least one processor in the pot body for controlling operation of the plant growing system;
• and
• c) a pot module interface on the base for detachably stacking the pot module atop a modular expansion platform comprising grow equipment, the pot module interface including one or more pot module electrical connectors for providing electrical communication between the control system and the grow equipment to expand plant growing functionality when the pot module is detachably stacked atop the modular expansion platform.

A modular plant growing system, comprising:

• a) a pot module including:
• (i) a pot body having a pot body base for supporting the pot body upright, a pot body top vertically opposite the pot body base, and at least one cavity open to the pot body top for receiving a plant growing medium, and (ii) a pot module interface on the pot body base and including one or more pot module fluid connectors for conducting fluid to the at least one cavity;
• and
• b) a modular expansion platform supporting the pot module and including:
• (i) a platform body having a platform base for supporting the platform body upright and a platform top vertically opposite the platform base,
• (ii) a platform interface on the platform top and including one or more platform fluid connectors, the platform interface interlockable with the pot module interface to detachably stack the pot module atop the modular expansion platform with the one or more pot module fluid connectors coupled to the one or more platform fluid connectors for fluid communication therebetween;
• and
• (iii) a fluid pump system in fluid communication with the one or more platform fluid connectors, the fluid pump system including a fluid pump and a fluid reservoir in fluid communication with the fluid pump for supplying fluid thereto to pump the fluid from the fluid reservoir to the at least one cavity of the pot body through the pot module and platform fluid connectors, the fluid pump provided in a detachable pump expansion module and at least a portion of the fluid reservoir provided in a detachable reservoir expansion module detachably stacked between the pump expansion module and the pot module.
