LED’s (Light Emitting Diodes) are widely considered to be the future of plant grow lighting. This is because LED manufacturers are achieving better and better control over the spectrum of light that comes out of LED fixtures through fine-tuning the array of LED’s on […]

HID lighting stands for High Intensity Discharge, which is a type of light that is one of the more intense (brighter) types of of lighting available. An HID lighting system consists of a ballast, reflector, socket and lamp (light bulb). The ballast acts like the engine, converting […]

Color Temperature is not how hot the lamp is. Color temperature is the relative whiteness of a piece of tungsten steel heated to that temperature in degrees Kelvin. For example, High Pressure Sodium lamps (HPS) have a warm (red) color temperature of around 2700K as compared to Metal Halide (MH) at 4200K, which has a […]

While the sun is the best “grow light” ever invented, only part of the light that comes from the sun is used by plants for photosynthesis. The photosynthetically active radiation (PAR) contains the wavelengths between 400 and 700 nanometers, and falls just within the so-called visible spectrum (380-770nm). The total visible spectrum is perceived by […]
