Disclosed herein are a plant cultivation light source and a plant cultivation apparatus. The plant cultivation light source includes a main light source and an auxiliary light source. The main light source emits light having at least two peak wavelengths. The at least two peak wavelengths fall within a wavelength region absorbed by chlorophyll.

Described herein are example portable indoor hydroponic garden assemblies and associated methods of use. The portable indoor hydroponic garden assemblies can include features that facilitate hydroponic gardening in an indoor environment, including structural features that enhance the indoor environment itself, such as through sounds, smells, textures, sights, and so on. In an example, the portable indoor hydroponic garden system includes a tiered growing assembly housed fully within an enclosure. The tiered growing assembly can include a group of trays defining tiers that are recessed from one another, allowing water or other fluid to flow from tray to tray, creating waterfall features there between that can aerate the water and emit a pleasurable sound to the indoor environment. The enclosure can be climate controlled and thus adaptable to a variety of indoor conditions to grow desired plants, including embodiments using programmable heating and lighting systems.

An aeroponic system with uninterrupted operation and energy saving comprises a first nutrient solution storage tank, a second nutrient solution storage tank, a gas storage tank, an air compressor and a planting module; compresses air in the gas storage tank mainly through the air compressor, and transports a nutrient solution stored in the second nutrient solution storage tank to the planting module for watering by gas pressure, the excess nutrient solution dripped after watering is recycled to the first nutrient solution storage tank, and is finally transported back to the second nutrient solution storage tank to complete a circulating supply system. Since operation is carried out through a high-pressure gas stored in the gas storage tank, an object of uninterrupted operation and energy saving can be achieved.

Water purification particles have porous particles and photocatalyst particles formed of titanium-based compound particles that are supported on the porous particles, have absorption at a wavelength of 500 nm in a visible absorption spectrum, and have an absorption peak at 2,700 cm.sup.1 to 3,000 cm.sup.1 in an infrared absorption spectrum, and a metal compound having a metal atom and a hydrocarbon group is bonded to the surface of each of the titanium-based compound particles through an oxygen atom.

A system for cultivating a crop includes a guide and a plurality of gutters. Each gutter is provided to contain a plurality of crop units and the guide is provided to guide the gutters in a first direction and to gradually increase the distance between adjacent gutters in said direction so that the number of crop units per square metre in the area substantially decreases. The area comprises first and second zones, and each gutter in the first zone contains crop units with a first intermediate distance and each gutter in the second zone contains crop units with a second intermediate distance. The first intermediate distance is considerably smaller than the second intermediate distance and the distance between gutters in the first zone at the position of a transition from the first zone to the second zone is considerably greater than the distance between gutters in the second zone.

A hydroponics system and method for growing flowering and/or fruiting plants is disclosed that involves a periodic flood and drain system combined with periodic spraying or misting of the plants and appropriate lighting systems and oxygenation systems. Specific flooding, spraying, lighting and oxygenation times and apparatus are disclosed.

According to aspect of the present invention there is provided the humidifier cultivation and process comprising:

Humidifier system and process of the humidity cultivation such that develops the humidification process in the cultivation system, it can be used to produce humidity, such as water, solution, vapor, gas solution, mist etc. That creates humidity into the system and recycles it. The system automatically controls the increase and decrease of the solution. Humidity generator and humidifiers comprising ultrasonic humidifier that determines the size of the atomize mist size is 2-8 microns.

This invention is a hydroponic appliance that allows users to grow sufficient yields of fresh produce with relatively little maintenance. The appliance incorporates multiple features required for hydroponic plant cultivation into a plug-and-play system with a feedback loop to manage optimal growing conditions, comprising a growing area, a processor, a mixing chamber, and, in embodiments, more than one reservoir. In aspects, the grow area is divided between two or more reservoirs allowing users to stratify their crops or plant different crop types simultaneously. The apparatus and associated method provide the overall system with increased versatility, including removing aspects of day-to-day maintenance. The system automatically regulates the environment in response to various sensor readings. This includes automatically regulating the temperature, humidity, carbon dioxide level, pH level, and/or nutrient concentration. Accordingly, the plants have more optimum conditions for growth. The system utilizes, for example, pre-seeded trays, a single mixing chamber, a processor, and a plurality of reservoirs.

An aquaponics system utilizing_portable hydroponic growing apparatus suspended over an aquatic holding vessel. The vessel is filled with water and stocked with aquatic organisms. A pump of sufficient lift connects to plumbing which runs over the top of the portable hydroponic apparatus. The hydroponics apparatus are suspended directly over the water vessel in such a way that the water drips back into the holding vessel below. Drip rate control emitters maybe installed to regulate the flow of water from the pump. This embodiment works well for low to medium intensity production. For higher intensity production, dedicated filtration and aeration devices are added.

There is provided a hydroponics device including a cover forming an upper part of a cultivation planter and a cover support supporting the cover from beneath the cover and detachably connected to a pan. The cover supports plants, which are a predetermined number of different strains of the same species, so that tips (portions respectively including rootcaps and apical meristems) of taproots of the plants are immersed in a nutrient solution in the pan.
