Why light recipes matter?
A light recipe that caters to a plant's needs can enhance photosynthesis, increase yields and improve produce quality.
Is efficacy the higher, the better?
Theoretically, a high efficacy indicates a less energy consumption, but it also means an increased manufacturing cost. It's advised to consider grow space, light intensity and ROI before purchasing a grow light.
Why LED?
LED consumes less energy compared with incandescent lights and HPS, contains no heavy metals, responds quickly and operates under quick switches. LED is also a cold light source that generates less heat and can serve a longer time.
What is LED?
LED refers to Light Emitting Diode, which is made from chemical compounds such as Ga, As, P and N.
Is full spectrum better for crops?
Full spectrum is close to the sunlight, which is suitable for all crops in a broad sense. But plants have varied needs for spectrum at different life stages, a designed light recipe can better increase the yield and improve the produce quality.
What are PAR, PPF and PPFD?
PAR, short for Photosynthetic Active Radiation, refers to the spectrum between 400-700nm that plants use for photosynthesis. PPF, a.k.a. Photosynthetic Photon Flux, is the total micromoles of photons (400-700nm) an artificial light generates per second. PPFD, short for Photosynthetic Photon Flux Density, refers to the total amount of photons (400-700nm) an artificial light generates that hit an area every second.
