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.
An LED will fill the role of the Sun; this much is simple to learn. What you may not have known is that the LED can actually be used in a highly customized environment to promote different types of growth. When a plant is just a seed, for instance, you may want to use a different color of LED to promote growth. Mature plants would do better with other wavelengths of light.
The lighting that an LED provides is so energy efficient because there is little heat that is given off. That is a mixed blessing. While you save money on energy costs, you will also have to spend extra money to heat the room if the temperature is too low. This is important during Winter, when temperatures can get dangerously low. A heating unit will have to be installed.
In addition to the lack of heat an LED will give off, and the problems you will face in cold situations, you will have to make plans to counteract the effect of less evaporation. Normally you would water a plant vigorously in the Summer to make up for the evaporation. While indoors and with little heat emitted, you will not have to water a plant so much. Take care that you are not watering the plant too much, for fear of damaging it beyond repair.
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.
If at first you notice that your LED light doesn’t seem to be emitting much like, don’t worry. LED lights emit a different wavelength of light, and you can be rest assured that the plants are still getting an abundance of light necessary for photosynthesis. You can also supplement lighting with a proper soft-white light bulb to encourage the development of fruit in plants such as tomatoes.
In Conclusion
Gardening is so much easier when you have the power of the LED on hand. Look at gardening manuals that reference LED hydroponics to get more familiar with the basics. Such manuals will also steer you clear of common mistakes that will keep you safe from harm when first starting out.
