A plant watering device. The plant watering device includes an outer container having a plurality of apertures on a lower portion of a first sidewall, an inner container having a second sidewall defining and open upper end and an open lower end, wherein the second sidewall of the inner container is secured to an interior surface of the first sidewall of the outer container via a fastener; and an apron encircling an outer side of the first sidewall. The plant watering device is securable to the ground via a stake. In use, water is poured into the inner container, flows through the open lower end of the inner container to the outer container interior volume, and then exits the apertures of the outer container. This allows the water to gently diffuse around an area where a plant is planted, while the apron prevents soil erosion and damage to the plant.

A plant watering assembly for retaining water around a plant includes a canister that is positionable around a plant. The canister is comprised of a fluid impermeable material thereby facilitating a fluid to be poured therein. Thus, the canister retains the fluid around the plant for nourishing the plant. The canister has a plurality of spikes thereon and each of the spikes pierces ground when the canister is positioned around the plant. In this way the spikes inhibit the canister from being displaced.

A self-contained air filtration system is disclosed herein. The system includes a processor. The processor can receive data from one or several components of the system and can provide control signals to one or several components of the system. The system can include a housing. The housing can include: a reservoir portion; and a greenhouse portion. The greenhouse portion can connect to the reservoir portion via a grow tray. A top of the reservoir portion and the greenhouse portion define an enclosed volume. The greenhouse portion can include an inlet aperture and an outlet aperture. The inlet aperture can be obstructed by an inlet filter such that air flowing into the greenhouse portion passes through the inlet filter, and the greenhouse portion can be connected to a fan that can propel air through the inlet aperture and out of the outlet aperture.

A self-watering planter comprises an outer shell, an inner shell and a water delivery device having a valve element. The outer shell is defined by a bottom surface, a body section and a top opening providing access to an interior. The inner shell is defined by a bottom surface, a body section and a top opening providing access to an interior. The inner shell is sized to be smaller than the interior of the outer shell such that when the inner shell is disposed within the interior of the outer shell, a hollow area is formed between the inner shell and the outer shell for retaining water. An opening is formed through a rim of the planter to provide access to the hollow area for water to be received and stored, and water is metered into the interior of the inner shell by the valve element.

A plant pot or a plant pot insert includes a water filling chamber having a fill opening to receive water, a water outlet to provide water to a water reservoir, and an overflow conduit to discharge excess water through a weep hole on a sidewall of the plant pot. The water reservoir provides water to a root system of a plant to be grown in the plant pot by capillary action. A water level sensing unit detects a water level of the water reservoir.

An indoor system and process for cultivating, harvesting, and outputting a culture of aquatic plants, namely duckweed, are provided. The system includes a water treatment system and cultivation and harvesting system. The water treatment system provides for mixing of nutrients and treated water to form a treatment mixture which is supplied to the cultivation and harvesting system for facilitating growth of the duckweed.

Disclosed is a hydroculture pot that can store an optimum amount of water at which a water level is appropriate for a depth of roots. A soil culture pot, having a supply and drainage hole that enables supplying and draining of water in a bottom portion, is used and a partitioning wall, vertically partitioning an interior of the pot main body in a watertight manner to store an optimum amount of water at which a water level is appropriate for a depth of roots of a spider plant, is disposed at an inner circumferential surface of a pot main body. An interior of the pot main body is filled with hydroculture soil and the optimum amount of water is stored in the pot main body so that the water level appropriate for the depth of roots of spider plant planted in the pot main body is a maximum level.
