lux to PPFD Convertor – Online calculator

Convert LUX to PPFD Converting LUX (Lumen/m²) to PPFD Photosynthetic Photon Flux Density. The Conversion-factor is depending on the light spectrum.  Note: a higher value does not indicate a better or more efficient light source. LUX / light-meter are much less expensive than a quantum spectrometer to measure PPFD. Also, every state of the art…

LED Test, Performance and Chemical resistance Seoul 3030C Vs SAMSUNG LM301 B/H

MID-POWER LED Comparison : Seoul 3030C vs SAMSUNG LM301 B/H Before hortiONE released the first product, we created numerous prototypes and carried out tests with different LEDs on the 3030 platform. Seoul and SAMSUNG provided the best performance on this platform. That’s why these two types have been reviewed and tested in more detail. Performance…

Light Spectrum and absorption curves for horticulture

Light Spectras and Absorption Curves for horticulture When we talk about plants and their interaction with light, we mostly talk about photosynthesis. But this is only a small part of the story, there are numerous other mechanisms controlled by light.  This article aims to help understanding the different mechanisms. Due to the complexity, we just…

Sulfur Resistance – Why Seoul 3030c?

The Role of Sulfur in horticulture Sulfur as Secondary Nutrients Sulphur (S) is an essential element in forming proteins, enzymes, vitamins, and chlorophyll in plants.  Sulfur is a so-called Secondary Nutrient. S activates several enzymes S improves crop winter hardiness S has an important role in photosynthesis S is important for plants with high oil…
