Hydroponics gardening is a technique through which plants are cultivated without any need of soil. Studies tell that soil is only needed for its mineral contents by the plant. The mineral contents are absorbed by the plant when they are watered and the nutrients dissolve in the water. Hydroponics is a technique by which it is possible to provide the plants with the necessary nutrients artificially. Hydroponics Gardening is essentially not much different from any kind of indoor gardening when it comes to the use of grow lights.
Grow lights are needed for proper synthesis of food as well as growing and reproduction in plants. The most often used grow light is the HID grow lights. High intensity discharge light come in many varieties which all have a digital ballast to keep check on the electricity passed through the lamp to ensure that it is working efficiently. Two kinds of HID grow lights are HPS grow lights and metal halide grow lights. Conjunctions are also used with a reflector which makes the light of the bulb purchased more intense. Metal halide grow lights are quite efficient and beneficial. Run with the help of argon gas, mercury, alumina, lots of metals and vapor HID grow light proves to be quite advantageous in magnifying the light produced by small bulbs. HPS grow lights also known as high pressure sodium lights are not much unlike in composition than the MH lights. HPS grow lights use sodium, mercury, xenon for functioning and they also require ballast to ensure smooth functioning and stabilize the whole process.
Another very popular kind of grow light is the LED grow lights . These kinds of grow lights are relatively inexpensive and are ideal for hydroponics. They are light in weight and easy to maintain. They produce light in a number of colors making it quite effective in helping the plants growth. LED lights are not much different from the one’s put on the Christmas trees. LED grow lights have a diode of whose function is similar to of a semi conductor. The light emitted is very bright and the lights are surrounded by reflectors. Reflectors magnify the light and once coupled with a lens it can be specifically used to direct light in any particular direction one may want.
Every plant has a need of different type of grow light and one must determine the type of grow light by considering not only the cost but also the color spectrum needed by the plant to flourish.
