Keeping your grow light reflector clean is another topic we will address in an upcoming maintenance blog. It also provides a corrosion resistant surface and a low sensitivity to pollution. PL’s grow light reflector has a highly reflective finish which provides diffusion. So, when you are looking at a grow light reflector, ensure that you are getting maximum reflectivity from a shiny, curved and dimple textured surface. a smooth surface will also diffuse the light and provide more coverage. White is a reflective medium, but it is not as reflective as a shiny aluminum type surface. Basic Physics….Flat surfaces do not reflect as efficiently as a curved surface in a reflector. Reflector patterns, materials and shapes really affect the dispersion of light and how it is distributed out of the grow light reflector. This will have an impact on your crop and your pocketbook. The lower lit areas will also have a lower rate of photosynthesis due to the lower light intensity creating less growth. Alternatively, an unevenly lit crop will have darker areas that will be over watered and over fertilized if you are meeting the higher lit crop areas’ needs. How can uniformity affect the health of your crop and yield? Simply, an evenly lit crop will consume all inputs such as nutrients, water, CO2 etc. Maximize your uniformity and reduce the number of light fixtures you require to achieve your light levels and crop quality. The right grow light reflector will increase your light output. Uniformity is critical for the health of your crop and to generate consistent growth and yield. When we are looking at High Intensity Discharge (HID) lighting like HPS, the purpose of a grow light reflector is to efficiently get that light down into your crop-while spreading that light evenly or uniformly over the crop. Let’s discuss the importance of your often forgotten and yes, sometimes neglected (luminaire) grow light reflector.
