Greenhouse lights are electric lights that aid in the growth of plants by replicating the sun’s light and offering a more suited spectrum to the demands of the growth cycle.
The art of greenhouse lighting is much more nuanced than simply making sure your plants get direct light. Growers looking for the right lighting in their greenhouses should consider the following three things:
- The type of crop being grown
- The time of year
- The amount of sunshine available
Greenhouses need six hours of direct or full-spectrum light on average each day. However, if this can’t be done naturally, growers need to use greenhouse lighting systems to ensure plants will thrive. The employment of numerous, high-intensity artificial indoor greenhouse lights to boost crop growth and production is known as supplemental lighting. Commercial farmers employ this method to improve yields and profitability, while hobbyists with a green thumb use them to sustain growth and lengthen the growing season.
Photoperiod control lighting is just as essential as supplementary lighting, as the cycle of lighting your plants need will vary. A photoperiod is the number of hours a plant gets light over 24 hours. Depending on the plant’s demands, photoperiod control lights imitate long or short days, used to trigger early blooming or support delayed flowering.
Growers have various greenhouse lighting fixtures to choose from, so it’s vital to understand the advantages and differences between them in order to make the right choice.
Advantages of Greenhouse Lights
Everyone already knows plants can’t thrive without sunshine. They develop best when exposed to their required amount of sunlight throughout the day to support the growth cycle. By integrating greenhouse grow lights into your system, plants will grow quicker and stronger, resulting in a shorter harvest cycle and a higher quality yield.
LED greenhouse lighting can be entirely recycled, making them a more ecologically friendly alternative to HID lights. HID lights not only use more energy, they also contain a significant amount of mercury, which may be harmful to the environment when burned. Greenhouse LED grow lights are energy-efficient and free from harmful chemicals, guaranteeing you and your plants are safe.
Using greenhouse lights to power your plants also creates a highly controlled environment that drastically lowers the need for pesticides and chemical treatments.
You can realize your plants’ growth potential through the proper application of greenhouse lighting. Effects including growth rate, stretching, and photoperiodism can occur at specific light wavelengths and wavelength proportions. Plant development and responses have been hampered for years by low quality greenhouse lighting systems, such as metal halide, high-pressure sodium, and fluorescent.
Greenhouse LED grow lights offer a greater and more diverse range of harvesting and plant growth options. It’s a distinct advantage over traditional HID spectrums, regardless of LED range, as HID lights often generate less and lower quality color rendering than LED greenhouse lighting.
This is a significant advancement in lighting technology, and greenhouse lights now enable growers to produce various plant reactions, such as the growth of new leaves or the harvest of sprouts based on light level and wavelengths.
Some plants may be sensitive to UV, IR, direct sunshine, heat, and other elements. Intense light can burn certain plants, indicated by the browning of leaves. However, when you use greenhouse lights, you can regulate heat and light to the correct level without reducing the wavelengths required.
An LED greenhouse lamp has a unique advantage over other lighting options in that it produces considerably less heat. Most plants are damaged by intense heat, slowing their maturation and growth and resulting in a shorter lifespan. LEDs operate at a lower temperature than HID lights, simplifying ventilation operations and expenses while reducing adverse environmental effects.
Commercial greenhouse lighting can be situated closer to your plants than standard HID bulbs due to reduced heat output. Lamps may be placed even a few inches from the plant without damaging them. This flexibility can be particularly beneficial for plant owners who have limited space for mounting lights in their indoor gardens.
Because of the size and height of greenhouse LED grow lights, you can assist them in reaching the canopy of a plant with maximum light. They may be placed closer to the plants depending on your grow light’s photosynthetic photon flux (PPF), allowing you to follow the manufacturer’s instructions for the proper distance between bulbs and plants.
Keep in mind that the mount’s form and the light’s strength will affect how near your plants should be to the greenhouse lamp. Smaller box-shaped lights perform better when positioned over a plant canopy, enabling light to spread until the plants are reached. Large-beam fixtures allow you to position the light closer to the plants. Install greenhouse lights with shorter beam angles if the light has to be further away from your plants.
Greenhouse lights are one of the best alternatives if you’re searching for a low-cost addition to your indoor garden. They can enhance the overall aesthetic of a room while also providing the necessary light for your plants. You can select various shapes and sizes to get the perfect lighting for your plants.
Aside from their high luminosity, LEDs are excellent grow light bulb alternatives as they can last over 10 years without repairs or replacement. Unlike HID bulbs, which need to be replaced every few thousand hours, these diodes do not need to be replaced as frequently once installed.
Another advantage of LED greenhouse lighting is that it’s more adaptable and customizable than other lighting options. Many LED growth panels are versatile, and you can replace components such as PCB boards, lenses, drivers, and fans with new features. This flexibility is crucial for indoor greenhouse lights, as it allows you to adjust the positioning of your lamps based on the size and height of your greenhouse.
What are Different Types of Greenhouse Lighting Fixtures?
LED (light-emitting diode) fixtures have the greatest longevity, with a usual lifespan of 50,000 hours. An LED’s diode doesn’t burn out as quickly as ordinary light bulbs, which is why it has such a long lifespan. This longevity is due to the fact that more of the power input goes towards generating light as opposed to heat, making LED greenhouse lighting fixtures more efficient than conventional lighting. Incandescent lights, for example, are only around 20% efficient since the majority of their input electricity is used to generate heat.
One of the most significant advantages of LED greenhouse lighting is the considerable energy savings. Compared to high-intensity discharge (HID) lighting, they’re simple to integrate into any operation and can save up to 70% in power consumption.
There’s no need for a warm-up period with an LED fixture and they’re mercury-free, making disposal considerably more manageable than conventional bulbs. When utilized as a sole source of light, LEDs provide greater functionality, making them an appealing alternative for all growers.
T5 fluorescent lamps are the most efficient and widely used greenhouse lighting fixtures. They consume less energy and may last up to 50,000 hours, compared to conventional grow lights. For optimal efficiency, these eco-friendly lights may use metal reflectors. They’re great for hydroponics, greenhouses, warehouses, and barns, among other things. Growers can utilize them from the beginning of seedling growth to the end of full-term development.
The greenhouse lamp’s tubular form is indicated by the letter “T,” and its diameter in eighths of an inch is indicated by the number 5. T5 fluorescent tubes are thin, with a diameter of only 5/8″ of an inch, making them more efficient than conventional fluorescent tubes.
Although they seem bright-white to the naked eye, ceramic metal halide lamps are utilized for their blue light. With a typical lifespan of 8,000 to 15,000 hours, they can readily serve as a primary light source.
However, it’s worth noting that metal halides must warm-up for approximately 5 minutes or less before emitting full brightness. They also require a 5- to 10-minute cool-down time. As a result, ceramic metal halides should not be used in areas where lights will often be turned on and off.
High-pressure sodium lights have a golden-white look and give off orange and red spectrum light. These bulbs are about seven times more efficient than incandescent lights and perform best when combined with natural sunlight, making them an excellent choice for greenhouse lighting systems. High-pressure sodium lights can boost intensity and photosynthetically active radiation (PAR) by 10%. These greenhouse lights are often employed later in the plant’s cycle because they encourage budding and blooming.
