When it comes to indoor plant cultivation, it’s always been hard for people to find a good source of light
comparable to sunlight. Before greenhouse farming was revolutionized by LED technology, gardeners
were trying to cultivate plants using traditional lighting, like high pressure sodium lamps (HPS) and
compact fluorescent lights (CFL).
These options weren’t good enough bercause they were not exactly meeting the needs of growing
plants, and other options seemed to be very costly. This has resulted in the increased uptake of LED
lighting in plant cultivation. These days, gardeners have found LED grow lights to be very useful for
cultivating plants indoors and can now grow fresh and healthy crops throughout the year no matter the
season. Apart from simply “going green” or reducing power consumption, there are lots of benefits
associated with growing plants using LEDs. Read on to learn more.
Tailored quality of light to produce better yields
LEDs allow gardeners to get more control over their greenhouse environment, in which they can use
different light inputs to increase their crop yields. Gardeners can customize light spectrums specifically
to the requirements of their crop, instead of generating unnecessary light that’s ineffective.
Eco-friendly: Less humidity and heat
The heat produced by LED grow lights is less strong than that produced by hot filaments of previous
generation bulbs. Particularly if high pressure metal or sodium halide lighting is used for long hours
every day, it produces plenty of heat which raises environmental humidity and temperature inside the
greenhouse. This requires extra ventilation for circulating air and cooling the environment to prevent
excess heat or destruction of the crop. However, with LEDs, gardeners can control indoor humidity and
temperatures easily. As LEDs have less thermal output when compared to several other conventional
bulbs, they help keep the indoor environment cool and boost growth.
Energy savings and increased lifespan
In an environment which requires constant lighting for growing plants, energy consumption and bulb
lifespan are vital and that’s why LED grow lights shine. LEDs that are manufactured using premium
components consume less energy and are more efficient. They also have long shelf lives and can work
efficiently for years without needing to be replaced or upgraded. Some gardeners consider LED lighting
as a huge investment but they don’t know that they can recoup their investment within a short time due
to the extended lifespan and energy efficiency of LEDs.
Stimulate early/uniform plant growth
Compared to traditional sources of lighting, LEDs generate narrow spectrum light that’s highly absorbed
by plants and may easily be customized for different growth needs of plants at various stages. The key
stage of crop development is the initial vegetative phase, where the crop needs the right intensity of
light to stimulate growth. The majority of conventional lights aren’t suitable for this phase because they
can’t generate a uniform light.
They generate light from one part of the bulb, which may be too strong for crops that are closer. This
means that plants closer to the lighting get too much light compared to those that are at a further
distance. Supplying too strong light at the early vegetative phase can lead to damage or even hamper
further crop development. However, LEDs are extremely effective during this phase too, because they
generate even light via all parts of its surface. With LED grow lights, cultivators can make sure light is
uniformly distributed no matter the plant’s location within the indoor setup.
Flexible design and placement
Another hurdle that gardeners usually face when it comes to greenhouse cultivation is the challenge of
placing grow lights. As LED grow lights are comparatively smaller than their alternatives, they are flexible
in terms of design and placement. Farmers can use different LED lights according their farming needs.
Moreover, the ability to place LEDs nearer the plants lets farmers have flexibility in urban farming
environments. They may use various cultivation methods, including multilayer farming which involves
stacking layers of garden in one growing space to increase production volume.
Thus, if you’re considering setting up a new grow light or switching to LEDs from conventional HID
lighting, the best time to do that is during the winter. The results will surpass your expectations and the
environment and your budget will thank you.
