As they definitely can be easily grown with all the absence of soil, hydroponic plants still need two other pursuits to survive - water and light-weight. Thanks to the developments in agricultural technology, plants don't need to be placed in areas that receive adequate light from the sun. Growers and hobbyists may either choose from LED (light emitting diode) grow lights, HPS (ruthless sodium lights, or MH (metal halide) lights. Although there are other lighting alternatives on the market, these three will be the most popular among hydroponic gardeners.
Phone History of Hydroponics
Contrary to popular belief, hydroponics' origins are in fact very old. Before the term was even coined, ancient cultures have previously practiced a rough version with this growing technique. It's even declared that the Hanging Gardens of Babylon have been, one of the oldest known hydroponic gardens.
Hydroponic technology however, only shot to popularity in the 19th century, after researchers found out that plants absorbed mineral nutrients by means of inorganic ions in water, which essentially resulted in they did not need any soil whatsoever.
Light Still Important
While hydroponic gardening provides growers and hobbyists the opportunity to grow plants, vegatables and fruits inside the comforts of the homes and minus the mess that comes with soil, lights are still very necessary. In order for photosynthesis to occur, plants need all the light they can get. Hydroponic lights behave as an alternative to sunlight, plus allow hydroponic gardens to get placed virtually anywhere in your home. As mentioned earlier, you have a quantity of choices when it comes to hydroponic lights, each one with its share of advantages and disadvantages. Each light is aimed at gardeners with different needs, therefore it is best to determine your lighting requirements before making any choices.
Which Light is for you?
From the 3 main hydroponic lights, the right one for you? Metal halide lamps are miniaturized versions from the streetlights littered along streets and freeways. Despite their small size, they offer a lot of power without eating the electric bill. Unfortunately, it's likely you have to spend more on the special fixtures required these lights.
Underhand sodium lights are created specifically for mature plants which can be at the flowering stage. Despite using little energy, HPS lighting is very powerful-they also go far. However, because HPS lights produce higher lumens, they also generate more heat. Expect to install fans and hoods to cool down the down your garden.
LED lights are prized because of their power-saving qualities. These bulbs eat the least electricity, and create little, to no heat in any respect. For plants that need warm environments, LEDs are certainly not recommended. If you would rather go the LED way, expect to cough out cash to set up more lights.
