Before the 1970s, it was a "primitive era"! People believed that plants could only survive under a continuous spectrum (such as sunlight or old-fashioned electric light sources). Why? This belief stemmed from the lack of effective tools in those days!
In the 1960s, red LEDs appeared; in the 1990s, blue LEDs appeared. This directly led to a revolution in plant photobiology. We discovered that plant spectral requirements are selective, discontinuous, and substitutable!
Of photosynthetically active radiation, red and blue light are the most important for plant photosynthesis! You see, scientists can use red-blue combined light to replace the traditional continuous spectrum to cultivate higher plants, such as wheat. This means we've simplified artificial light cultivation from a complex continuous spectrum to a highly efficient red-blue composite light quality! This simplifies lamp design and significantly reduces manufacturing costs, directly boosting the return on investment in facility agriculture!
2. Only a red-blue spectrum solution?
Red and blue light are essential for plant survival; that's true. But if you want to achieve specific goals in yield and quality, red and blue light alone is far from enough!
What we're aiming for is "beneficial light quality", which includes other visible light besides red and blue, UV (ultraviolet) light, and IR (far-red) light!
And UV-IR behavior is especially powerful in fast-cycle crops like rice, as explained in Strive for 1/1 Acre Rice Yield.
You can't use one set of LED grow lights to illuminate the entire growth cycle! This is completely contrary to the physiological rhythms of plants! If your grow lights cannot provide dynamic spectral adjustments according to the crop's growth cycle, then your energy investment is a serious waste!
Plants' light quality needs are phased! This is the core logic behind our professional LED grow lights:
Germination stage (spring): Requires IR and heat.
Vegetative growth stage (summer): Requires more blue light, focusing on morphogenesis.
Autumn maturation stage: Requires more red light to promote photosynthesis and carbohydrate accumulation.
3. Professionally led grow lights for different light quality stages
This is also why JT Photoelectric stands out in the fierce market competition! Our products go far beyond basic red-blue light combinations, focusing on solutions covering the entire life cycle and the entire spectrum!
Advantages of JT Photoelectric's lighting systems:
1) True full-spectrum LED grow lights
We understand that while sunlight is not the "optimal" spectrum, it encompasses all physiological effects. Our full-spectrum LED grow lights go beyond simple red and blue light by providing a continuous, balanced, and efficient spectrum. This ensures that plants absorb all beneficial light qualities, maximising your crop's dry matter production, as plant dry weight is the most convincing indicator of the effects of light quality.
2) LED grow lights with UV-IR technology
This is a disruptive core technology! Our lights can precisely control the ratio and intensity of UV and IR. Providing IR during germination promotes growth, while UV at specific stages enhances plant resistance, pigment deposition, and flavour. Our LED grow lights with UV-IR solutions ensure your crops not only grow faster but also achieve higher quality, commanding higher prices!
3) High-quality products and services
JT Photoelectric is committed to providing professional LED grow lights. Our lights not only have high luminous efficacy but also prioritise energy efficiency. Our systems provide the most energy-efficient total light output and photoperiod based on different plant species and growth stages, maximising energy savings! Our professional services include determining your crop's spectral response curve, providing the optimal red-blue light ratio and photoperiod scheme, and ensuring every penny you invest is well spent!
Light is the plant's "nutrient", directly affecting its photosynthetic response (vegetative growth and energy production) and photomorphological response (morphological development and pigment synthesis).
You can no longer waste energy with outdated knowledge and inefficient grow lights! Remember, there are two main ways to improve the efficiency of your lighting system: first, determine the plant's needs; second, provide artificial light on demand!
JT Photoelectric has prepared the second way for you! Our full-spectrum LED grow lights, especially our professional LED grow lights incorporating UV-IR technology, perfectly match the light quality requirements of plants at different stages of growth, taking into account spatial, temporal, species, and varietal differences.
It's time to ditch those ordinary lights that only keep you "alive"! Choose JT Photoelectric, and with precise spectrum and top-notch technology, let your crops grow stronger and of higher quality, truly achieving your commercial goals of energy saving, high yield, and high quality!
