  • Patent number: 10667476
    Abstract: A sustained release irrigation apparatus for effective water management. The sustained release irrigation apparatus includes a reservoir, a support structure, an absorbent surface, a water permeable top layer and a top opening on the water permeable top layer for filling water in the reservoir. The support structure is positioned on the reservoir and designed to support a potted plant thereon. The absorbent surface is positioned on the support structure and includes an absorbent opening. The top opening positioned on the water permeable top layer receives water from a water source and fills water into the reservoir. The water collected in the reservoir flows upwards to the water permeable top layer and then reaches the soil inside a pot thereby making water available to the roots of the potted plant without any wastage.

  • Patent number: 10251349
    Abstract: A multiple plant container self-watering system comprising a frame supporting multiple grow pots, the multiple grow pots comprising at least a primary grow pot and a secondary grow pot; a primary container at a first elevation on said frame wherein said primary grow pot rests on a primary wick of the primary reservoir pot, and a plurality of secondary containers, each of the plurality of secondary containers being at a different elevation and comprising a secondary grow pot resting on a secondary wick of the secondary reservoir pot; whereby the primary container and the plurality of secondary containers are fluidly connected by means of the tubing and configured to allow for substantially similar dry-down time.

  • Patent number: 9241452
    Abstract: A multiple plant container self-watering system comprises a primary container at a first elevation and a plurality of secondary containers at different elevations, fluidly connected by means of tubing. The primary container comprises a primary outer shell that encloses a primary reservoir pot, having an expanded upper portion and a tubular lower portion, a primary wick and a primary grow pot. Each of the plurality of secondary containers comprises a secondary outer shell that encloses a secondary reservoir pot having an expanded upper portion and a tubular lower portion, a secondary wick, and a secondary grow pot. The diameter of the lower portion of the primary and secondary reservoir pot is greatly reduced in comparison to the diameter of the upper portion thereof, thereby allowing for substantially similar dry-down time for a plurality of fluidly connected plant containers at different elevations.

  • Patent number: 8925246
    Abstract: A plant trellis system for growing plants on hard surfaces such as patios or decks is disclosed. The system comprises a trellis base having a plurality of cutouts, a pot having a plurality of legs protruding from the bottom surface, and a plurality of wire mesh panels supported on the trellis base. The plurality of legs is inserted into the plurality of cutouts forming a firm connection between the trellis base and the pot. The trellis base further comprises a groove on each side where a base wire of the plurality of wire mesh panels is inserted. The trellis base also comprises a plurality of notches on each side to receive the vertical wires coming from the base wire. Clips are used to attach each wire mesh panel to the adjacent wire mesh panel. The system is portable and stable beyond the boundaries of the pot to support larger plants.
