Abstract: A modular system for plants and air purification having a plant module with a containment portion for holding a plant growth medium and a conduit for passage of air therethrough. The modular system also contains an exhaust module having an inlet aperture for receiving air flow from the plant module, an outlet aperture and an air pumping unit arranged to pump air from the inlet aperture to the outlet aperture. The plant module and exhaust module are connectable one with the other, and wherein when connected air flow is permitted between the two units.

Abstract: A plant monitoring system for the monitoring of environmental parameters that affect growing plants and that is capable of producing audible and visible alerts when the health of the plant is threatened. In some embodiments, the plant monitoring system is configured to produce calibrated alerts specific to the type of plant being monitored based upon information stored in an on-line database. In still other embodiments, plants are remotely monitored by web-enabled devices which further allow for additional calibration settings to be entered by the user.
