The LED, or light-emitting diode, is a type of light that is considered extremely energy efficient. Gardeners are switching to this type of lighting for indoor gardening and hydroponics for the simple fact it’s cheap, effective, and greatly aids the development of plants.
LED lights are necessary for photosynthesis- a process that requires light such as the light received from the Sun. Normal lighting may not always do the job, and specific colors of LED light will be required depending on your plant and its current maturity. It is sometimes necessary to change LED lighting according to how old the plant is.
LED lights will not emit a lot of heat, unlike other types of lighting. For that reason you will want to find another means of finding heat for your plants if the room is not properly heated. A heater usually works best, but you can also supplement a heater with normal lighting, better insulation, and other techniques that hydroponics experts will be able to share with you.
You may also notice that your plants do not need as much water. This is because there is less heat from the LED lighting, and the water does not evaporate to the extent that it normally would. Pay very special attention to the amount of water your plants take in, and modify your watering schedule to ensure you are not over-watering your plants. Otherwise you could seriously damage your plants, or even critically injure them.
LED lights can also emit a chemical compound you are probably familiar with- CO2. Since plants need oxygen and carbon dioxide both, having an excess of CO2 would essentially suffocate your plants. You will want a CO2 meter to monitor the levels. If the levels are too high for the recommended average of your plants, you will want to work some ventilation into your hydroponics room. After all, plants have to breathe too- and oxygen is necessary for both human and plants alike.
The light level of an LED is considerably less than what you and I are probably accustomed to. While it would make for bad eye sight, plants are just fine in a lower light level. Plants only need a specific aspect of the light, and can do fine in low-brightness environments. Even still, you may wish to install secondary lighting so that you can see better if your current LED equipment doesn’t leave you satisfied.
Final Thoughts
LED lighting is highly recommended for indoor lighting purposes in regards to hydroponics. You will of course want to learn more about the subject before putting into practice. Ask for an informational booklet to read up more on the lighting source with your purchase at your gardening center.
