Ceravision is a privately owned lighting company based in Milton Keynes, UK. Ceravision is the inventor of High Efficiency Plasma (HEP) lighting technology, a new and unique genre of electrodeless lamps, driven by radio frequency (RF) and particularly suited to medium and high power commercial applications."Switched on to a bulb that lasts", The Sunday Times"Everlasting Light", The Economist HEP lighting technology is ideally suited for a number of high-output commercial lighting applications. Ceravision has exploited the ability to use various doses to efficiently deliver tailored spectra for particular applications. The company has launched an HEP plasma grow-light for the horticulture and hydroponics markets that delivers the blue-light, UV-A and UV-B missing from most available grow-light spectrums in the market.

An HPS (High Pressure Sodium) grow light bulb in an air-cooled reflector with hammer finish. The yellowish light is the signature color produced by an HPS. High- pressure sodium lights are a more efficient type of HID lighting than metal halides. HPS bulbs emit light in the yellow/red visible light as well as small portions of all other visible light.

This cactus has 11 to 12 thin and white radial spines that range from 8 to 10 mm long. Their 3 to 4 central spines are dark brown and are commonly 10 mm long. Mammillaria fraileana grow light pink flowers with a darker pink median line. These flowers are 2.5 to 3 cm in diameter and their stigma is bright pink.

Fluorescent lighting was formerly the most common type of indoor grow light but HID lights have surpassed them. High intensity discharge lamps have a high lumen-per-watt efficiency. There are several different types of HID lights including mercury vapor, metal halide, high pressure sodium and conversion bulbs. Metal halide and HPS lamps produce a color spectrum that is somewhat comparable to the sun and can be used to grow plants.

Fluorescent grow light Fluorescent lights come in many form factors, including long, thin bulbs as well as smaller spiral shaped bulbs (compact fluorescent lights). Fluorescent lights are available in color temperatures ranging from 2700 K to 10,000 K. The luminous efficacy ranges from 30 lm/W to 90 lm/W. The two main types of fluorescent lights used for growing plants are the tube-style lights and compact fluorescent lights.

The quantity, quality, and duration of light regulate plant growth and development. In general, if a plant does not get enough light, it will become stunted, have reduced pigmentation, or begin shade-avoidance response. A plant that does not receive the right quality of light may exhibit physiological differences when compared to the same plants grown under optimal lighting conditions. Grow light quantity and quality has been technologically limited in the past.

In tests conducted by Philips Lighting on LED grow lights to find an optimal light recipe for growing various vegetables in greenhouses, they found that the following aspects of light affects both plant growth (photosynthesis) and plant development (morphology): light intensity, total light over time, light at which moment of the day, light/dark period per day, light quality (spectrum), light direction and light distribution over the plants. However it's noted that in tests between tomatoes, mini cucumbers and bell peppers, the optimal light recipe was not the same for all plants, and varied depending on both the crop and the region, so currently they must optimize LED lighting in greenhouses based on trial and error. They've shown that LED light affects disease resistance, taste and nutritional levels, but as of 2014 they haven't found a practical way to use that information. Ficus plant grown under a white LED grow light. The diodes used in initial LED grow light designs were usually 1/3 watt to 1 watt in power.

The majority of HPS lamps while providing good growth, offer poor color rendering index (CRI) rendering. As a result, the yellowish light of an HPS can make monitoring plant health indoors more difficult. CRI isn't an issue when HPS lamps are used as supplemental lighting in greenhouses which make use of natural daylight (which offsets the yellow light of the HPS). High-pressure sodium lights have a long usable bulb life, and six times more light output per watt of energy consumed than a standard incandescent grow light.

Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour, temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation (e.g. the germination/vegetative phase or the flowering/fruiting phase), and the photoperiod required by the plants, specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.

The most sophisticated examples are totally enclosed, and contain a built-in grow light, intake and exhaust fan system for ventilation, hydroponics system that waters the plants with nutrient-rich solution, and an odor control filter. Some advanced grow box units even include air conditioning to keep running temperatures down, as well as to boost the plant's growth rate. These advanced elements allow the gardener to maintain optimal temperature, light patterns, nutrition levels, and other conditions for the chosen plants. Key growlight options include fluorescent bulbs, which offer relatively limited light output; high-intensity discharge lamps such as sodium-vapor lamps and metal-halide lamps; and light- emitting diodes bulbs, which are becoming more energy-efficient.

A rotary hydroponic cultivation demonstration at the Belgian Pavilion Expo in 2015 A rotary hydroponic garden is a style of commercial hydroponics created within a circular frame which rotates continuously during the entire growth cycle of whatever plant is being grown. While system specifics vary, systems typically rotate once per hour, giving a plant 24 full turns within the circle each 24-hour period. Within the center of each rotary hydroponic garden can be a high intensity grow light, designed to simulate sunlight, often with the assistance of a mechanized timer. Each day, as the plants rotate, they are periodically watered with a hydroponic growth solution to provide all nutrients necessary for robust growth.

Two plants growing under an LED grow light LED grow lights are composed of multiple individual light-emitting diodes, usually in a casing with a heat sink and built-in fans. LED grow lights do not usually require a separate ballast and can be plugged directly into a standard electrical socket. Individual LEDs usually provide only a single narrow range of colors, and so different color LEDs are mixed in grow lights in proportions depending on the intended use. It is known from the study of photomorphogenesis that green, red, far-red and blue light spectra have an effect on root formation, plant growth, and flowering, but there are not enough scientific studies or field-tested trials using LED grow lights to recommend specific color ratios for optimal plant growth under LED grow lights.

III "Britain, ask of thyself" – Solo Bass and Chorus (Tenor and Bass) Britain, ask of thyself, and see that thy sons be strong, See that thy sons be strong, Strong to arise and go, See that thy sons be strong, See that thy navies speed, to the sound of the battle-song; Then, when the winds are up, and the shuddering bulwarks reel, Smite, the mountainous wave, and scatter the flying foam, Big with the battle-thunder that echoeth load, loud and long; Britain, ask of thyself, and see that thy sons be strong, See that thy sons be strong, Strong to arise and go, If ever the war-trump peal; See that thy squadrons haste, when loos'd are the hounds of hell; Then shall the eye flash fire, and the valourous heart grow light, Under the drifting smoke, and the scream of the flying shell, When the hillside hisses with death, and never a foe in sight. Britain, ask of thyself, and see that thy sons be strong. So shall thou rest in peace, enthron'd in thine island home. So shall thou rest in peace, Enthron'd in thine island home, So shall thou rest in peace, enthron'd in thine island home.
