Growing indoors and employing L.E.D grow light technology is one of the newer methods employed in growing your plants effectively indoors. This promising new form of light is completely different than the standard (HID) high-pressure sodium and (MH) Metal Halide variety of grow lamps.
L.E.D grow lights contain multiple low-watt light bulbs which work together on a single processing board where HPS and MH lamps employ single, extremely high power bulbs to spread light over a greater space. LED Grow Light bulbs can be found in 1W, 3W, and 5W, while the more common HPS and MH bulbs are 400W, 600W, and 1000W, however other wattage’s definitely exist.
You want a system that tunes & test their chips to provide results, provides a warranty period which is rock solid (at least 2 years).
The vast majority of manufacturers use 120º degree lenses in their L.E.D grow lamps. This spreads the light out so much that the spectra have difficulty reaching the lower canopy of the plant. Companies are able to trump up the coverage areas of their lamps by employing this practice. This looks great in terms of numbers however it unfortunately does not create an optimal growing environment for your plants. High-end, smaller wattage grow lamps feature 60º degree lenses, which allow your plants denser, more concentrated lumens and better lower canopy coverage. Higher wattage units can employ a lens system which disperse light over a much wider area, generally 90º degrees, or a mix of 90º to 120º degree lenses.
When choosing a L.E.D grow light system you need to take into consideration the overall light intensity and coverage area as they both affect each other greatly You can measure both of these components by the viewing angle of the LED lens itself, which measures in degrees, a quality lamp’s viewing angle is created by a mix of custom lenses that can either focus the light tightly into one area, or spread the light out over a wide area.
Consider the reaction a plant receives by light direction alone. By employing a reflector to a High Intensity Discharge lamp you are able to focus the broad spectrums employed by the unit downward, creating more intense light penetration. You can employ the exact same concept with the directional intensity of the light emitted by our Pro-Grow L.E.D grow light series.
Chlorophyll absorption and L.E.D Grow Lighting: Plants convert light energy into plant energy via photosynthesis. There are two primary compounds that achieve photosynthesis: Chlorophyll A, and Chlorophyll B. These compounds absorb blue and red light, while nearly all other spectra are reflected away from the plant and into the nether. There is a term called the “absorption peak” which is the point at which Chlorophyll converts light energy into plant energy the most efficiently. These absorption rises can be measured in units called nanometers (nm).
L.E.D’s are light sources that emit narrow wavelengths of light, and can be tailored to nearly any nm that you as a grower desire. By using L.E.D’s at the same nm as each of the absorption points for Chlorophyll, quality LED systems convert light energy into plant energy much more effectively.
High Intensity Discharge lights emit full spectrum’s of light (most of which is unused by plants), quality LED systems like Hydroponic Hut’s Pro-Grow line emits only the spectra that plants require which results in much higher efficiency in terms of growth per wattage used. By using the ideal ratio of L.E.D’s, 95% – 100% of the light created is used for photosynthesis. The bottom line is that your plants will utilize less overall wattage with our lamps and produce the exact same yields you have been accustomed to as a grower under HID lamps.
