How does green light affect photosynthesis?
We often focus on blue and red colors in grow lights because chlorophyl can easily absorb those wavelengths. Green light however is often neglected, but should be a part of grow light strategy that can impact crop yield significantly.
How does light color affect Photosynthesis? A visual guide.
How does light color affect Photosynthesis? White light contains all the colors of a rainbow, and certain colors indeed affect photosynthesis in specific ways. This is a visual guide to colors and plants.
What does far red light do for plants?
Far-red light impacts plants in so many ways that it’s sometimes confusing, misunderstood, and even controversial. Nevertheless, it’s an important topic for indoor growers to grasp in order to harness the strategies of far-red light in their businesses.
Optimizing Indoor Agriculture: Leveraging the Power of UVA Spectrum
Indoor agriculture faces a challenge in delivering visually appealing, nutritious crops without natural sunlight. To overcome this, leveraging UVA spectrum light offers a promising solution. Research shows that controlled UVA exposure enhances fruit ripening, improving sweetness and flavor. Integrating UVA optimization into indoor farming practices can elevate crop quality, meeting consumer preferences effectively.
Hue, Saturation, Brightness and Spectrometers
When we talk about light and color, terms like Hue, Saturation, and Brightness frequently come up, but many of us struggle to explain them or grasp their significance. In this article, we aim to demystify these terms, explain why they matter, and show you how to measure them.
What is a Spectrometer, Spectrophotometer, Spectroradiometer?
3 Spectral Devices standout; Spectrometer, Spectrophotometer and Spectroradiometer. However these terms are often used interchangebly and results in misunderstandings. In this article we discuss the differences.
Do you know Why grow lights are purple?
Grow lights shine purple because they are arrays of bluish and reddish LEDs. And plants are most efficient at absorbing blue light and red light to conduct photosynthesis, that results in sugars used for many of the plants metabolic processes.
What is Light and where does it come from?
We non-scientists take for granted that light is just light, and hardly think about where it comes from or how it’s produced. So if your work involves light, lighting or even indoor farming, we thought you might like to know.
