Abstract: The present disclosure relates to the use of an aeroponic propagator for supplying fog within an aeroponic propagator for the cultivation of plants. An aeroponic propagator according to the disclosure comprises a fogging system for supplying fog within the aeroponic propagator, wherein the fogging system comprises a droplet generator, the droplet generator comprising at least one outlet, and the droplet generator being configures such that in use each at least one outlet ejects one droplet of liquid at a time.

Abstract: The present disclosure relates to the use of an aeroponic propagator for the cultivation of plants. The aeroponic propagator of the present disclosure may be a human intervention free system. The aeroponic propagator of the present disclosure may allow the total spectrum of all stages of plant growth from seedling to harvest and multi-cropping per system with minimum human intervention. The aeroponic propagator comprises a self-harvesting system for collecting produce from cultivated plants, wherein the self-harvesting system is configures to collect produce that has detached from the cultivated plants.

Abstract: The present invention relates a control system and method for supplying droplets within a space for controlling humidity. The control system comprises a droplet generator and a control unit. The droplet generator comprises at least one outlet and is configured to supply droplets to the space. The control unit is configured to control ejection of the droplets from the droplet generator to control the humidity in the space.

Abstract: Fire suppressant apparatus comprises a container (11) which may be spherical or cylindrical with domed ends, housing a liquid such as water in an interior chamber (25) and having low pressure nozzles (19, 20) housed in recesses covered by caps or covers (26, 27). A gas generator (22) is also located within the chamber (25) and contains a stable combustible material (21) which can be ignited by an ignitor (26) triggered by a sensor (28). The gas generated by combustion of the material (21) drives the water out through the nozzles (19, 20) to form fine droplets the majority of which are in the region of 50 &mgr;m without creating a high pressure within the chamber (25). The burn time of the gas generator material is 15 to 20 seconds so that a mist or fog lasting at least this duration is generated in the protected environment and can be carried to the seat of a fire by convection currents within this environment.
