Lighting is essential for plant growth and plays an important role in determining crop yields. Hydroponics growing equipment manufacturers therefore have a wide range of lighting designs include the specific needs of different crops grown to meet in the rooms.
lighting requirements vary depending mainly on the type of plant, the area of the plants are grown and the facility is its proximity to the source of light. The most important consideration is the level of lighting that a plant needs to grow healthy. Some plants such as ferns and indoor plants not as much light as salads and herbs need, while the tomatoes, orchids and flowering plants need as much light. It was observed that for indoor growers usually tend to illuminate the interior little room in their attempt to grow a large area, the ‘cover Backlight. You must understand the importance of adequate lighting in mind that a smaller area which is lit properly, will produce better results than a larger one with insufficient light.
Fluorescent lamps are ideal for small salad and herb gardens and the production of seedlings and cuttings. T-5 fluorescent lamps are suitable for the plants a little larger than the T-5 fluorescent lamps are equal in value to the pair of light 400-watt metal halide lamps. These lights should be kept near the plant on all sides, but are crops with short internode distances large, unless the plant is too large. T-5 are best suited for vegetative growth.
High-pressure discharge lamp lighting vegetables, flowers and various other varieties best you can with all the light, HID lamps and modern exactly what they need. HID lighting has been designed with improved lamp and reflector design a piece of equipment for special needs of an almost “plug and play”, the use of the laity. HID lamps are available in two versions – with remote ballasts and lighting and integrated. The remote ballast design has the advantage that only the light-reflector unit to be suspended from the ceiling, it requires an integrated design that lifted the entire unit, including the heavy burden of being. Are
HID lighting is available in two basic types of high-pressure sodium vapor lamps, metal halide lamps and high. Metal halide lamps, HID lighting produces a light blue and white, and has been recognized itself as particularly suitable for the whole plant growth, while sodium vapor high pressure lamps have a red / is orange is best for flowering and the period of fruiting bodies, where the plants easier it can use. Both types of HID lighting with producers either alternately on both the growth cycle of plants or the mixture of the two during the harvest. But the final design of the sodium lamps, which now in the “Agro” or a series of “Ground” can light energy during the growth cycle of plants and offer are increasingly used by professional breeders.
HID lamps are available in power 250-1000 watts and beyond. The lamp, which provides the maximum light output, wattage of the lamp lumens 600 watt sodium, which produced 92 000 lumens.
Reflector While it is important to use appropriate lights to indicate the amount and type of production of light is equally important to ensure that the light in a way that ensures minimal waste is addressed. Reflector design plays an important role in maximizing the use of light can be a well designed reflector up to 30% more efficient than wasting a poorly designed reflector according to their ability to minimize light. More efficient reflectors now supported on the real estate market designs using modeling techniques by computer. These designs maximize the reflection of light on plants and to improve the life of the lamp.
1. Light Movers In addition to enabling efficient reflectors, light rail, the movement of the lamp to ensure exposure to the most remote work go a long way in improving the use of light. A rail system called Light Rail 3.5 has proved particularly effective in improving the use of light and should be taken by those with a rectangular area of growth into consideration. This is a simple device that uses a two-meter track with a precision engineering company that moves forward and backward light on the culture surface. The light rail system offers advantages 3.5-ranging and covers a larger area to ensure that all plants immediately receive much light, but removes the plants have some exposure moves to eliminate light and shade it provides for a uniform growth of plants . It also provides more detail on the exposure of plants to light without burning the foliage. There are other systems that move the light along a circular path, they are better suited for square grow room. Some systems also allow the lighting with metal halide lamps in one arm and a high-pressure sodium vapor lamps in the other, or 4 different ceramic lamps on four separate arms, each with a different color temperature. These four different lamps combine to make a comprehensive offer, if offset by a circular light engine or rotation.
2 reflected light . Reflective surfaces near the area under cultivation can make a difference in the amount of light the plants get to make the poor reflectivity of the surfaces around the plant reduces the amount of light surfaces absorb a large portion of incident light. It is difficult to ensure highly reflective surfaces around the plants in a culture. The walls may simply with white paint, which is an excellent reflector can be painted. If this is not possible from the walls is black with a plastic / white, which can also be used for floors covered. Polystyrene foam sheets can also be used because it is a good reflection surface. The vinyl floor is bright white reflective. It is tough and hard and is a perfect reflective surface. Finally, the reflective Mylar material reflects 92% of the light it receives.
3 timer on and off automatic lighting requires the use of a timer effectively. The addition of a timer in the lighting set provides that the plant growth in space, light is exposed during the time “on” set up after the lights go out during the “off” time. The constant repetition of this cycle unbroken ON / OFF is essential, is a reliable timer, good quality and comfort. It is best to avoid, ungrounded current plug-in timers, because they cause too prone to breakdowns, disruption of flowering cycles in some plants and higher electricity bills.
Power The energy consumption is one of the factors taken into account, while the work of the economics of the project will be removed. But this general should not deter the novice and the associated costs are surprisingly small. The beginner should calculate the energy demand and its economy at first, to avoid problems later.
Warning Anything can be damp and humid areas. All electrical appliances, fittings and accessories are carefully placed to avoid contact with water spray. You should install the help of a licensed electrician in the electrical system.
