Photosyn is a high-end brand under ZOOX specializing in the cultivation of premium indoor plants and freshwateraquatic plants.
Due to the relative ease of caring for plants and freshwater species, many brands in the market offer low-cost products using existing light case and civil use LED chips combinations. However, keeping a plant alive does not necessarily mean it is thriving. Feedback from professional growers indicates that the current lighting spectrum available in the market is clearly insufficient.
The development of lighting LED chips for civil use focuses primarily on visible light intensity and cost, resulting in a spectrum that is far from replicating natural sunlight. Professional growers have also observed that while plants can survive and grow indoors under artificial lighting, the quality of growth is noticeably inferior compared to sunlight.
This includes aspects such as leaf expansion, leaf thickness, stem width, flowering, and fruiting cycles. Some brands prioritize the sales pitch based on the PPFD (Photosynthetic Photon Flux Density) value, believing that higher PPFD results in better plant growth. However, professional botanists point out that the concept of PPFD originated several decades ago as a reference parameter for the civil cultivation industry, which had limited knowledge in the fields of botany and light measurement at the time. PPFD was merely a reference value derived from visible light measurements used for photosynthesis.
With rapid technological advancements over the past few decades, numerous scientific and botanical studies have presented evidence that non-visible light spectrums such as UVB, UVA, and infrared have positive effects on plant development.
For example, plants use special pigments in three light-sensitive Photoreceptors, namely Phototropin (phot), Cryptochrome (cry), and Phytochrome (phy), to gather information from the incident light. These photoreceptors are highly sensitive to different wavelengths of light.
Recent studies have shown that these special pigments in the light photoreceptors respond not only to visible light but also to non-visible light such as UVA, 660 nm photo-red , and infrared, resulting in positive growth reactions.
However, traditional PPFD measurements are unable to detect these non-visible light spectrums.
Due to these findings, Photosyn introduces a new concept and research direction called “Light Quality.”
“Light Quality” refers to the quality of light rather than its intensity (PPFD). Using its proprietary technology, Photosyn simulates a spectrum that closely resembles 95% of sunlight, taking natural sunlight as the reference. This allows us to create the non-visible light that plants require, which is not perceptible to the human eye. As a result, even with equivalent power, the human eye perceives Photosyn’s sunlight as weaker compared to conventional consumer lighting fixtures
