VLOG; Comparing the Uniformity Pro Flex to the Uniformity Pro 640

Overview  Rugged, waterproof, glass lens, 100-277 VAC. This unit is built to last.  Our far red lightbar is the most popular 4' long 730nm grow light on the market today. Industrial grade construction. All aluminium housing. Internal LED driver.  About Growing with Far Red Energy Far-red light is good for plant growth. It can increase photosynthesis, enhance growth, and increase plant size. Far-red light is significant to plants because it increases the ability of plants to capture light. Plants use light not only as a source of energy, but also for information about the surrounding environment. Far-red light is typically not absorbed much by plant leaves, and it doesn't drive any photosynthesis because it is mostly reflected off leaves. However, if a plant "senses" a greater ratio of far-red to normal light then it "knows" that obstructions or other plants are close to it. Far-red light can also regulate leaf angle and increase plant height and leaf area, via expression of associated genes, to capture more light energy. The lightbar features a crystal lens that covers the diodes, making it waterproof and resistant to overspray. Additionally, the lightbar is designed to be easily moved and bumped around, making it one of the most versatile and user-friendly grow lights on the market. However, what sets this light apart from others is its ability to stimulate plant morphology. By emitting a high intensity of far red light, the FGI Far Red Lightbar encourages plant growth and development, making it the perfect choice for any serious gardener or farmer. Use far red energy in veg to keep plants compact and strong. Recent studies at Utah State University by Dr Bruce Bugbee, have proven that additional energy, even in the red spectrum, keeps plants more compact.  The science of using far red light on plants Recent studies at the University of Texas El Paso / University of Texas Arlington, concluded that plants exposed to full spectrum plus dosing with far red spectrum, increased overall plant mass/yield and also improved terpene profiles. Read the study here. The light coverage of this product is unmatched. It will fully cover a 4' wide grow tray in bloom and generally covers a 2' wide swath. We recommend a pair for each 4x4 grow space and this unit comes with hardware which allows you to position it inside the frame of most 5 and 8 bar full spectrum LEDs. This light system is one of the best on the market and will give your plants the light they need to thrive. Order now and be sure to get your grow space set up correctly so you can achieve maximum light coverage. Targeting the Emerson Effect. The Emerson Effect is the name given to the increase in the rate of photosynthesis that occurs when chloroplasts are exposed to far red energy just before the nighttime lights off cycle. This effect was first discovered by scientist Alexander Emerson in 1883, and it has since been extensively studied by plant biologists. While the Emerson Effect is typically associated with increases in photosynthesis, it can also lead to other changes in plant physiology, such as increased cell division and growth. One way to take advantage of the Emerson Effect is to use our supplimental far red LED grow light for 10-15 minutes after full spectrum lights are turned off. If you are looking to create the ideal environment for your plants, an LED grow light can help you to achieve the Emerson Effect.   Far Red Spectrum Use We recommend 2 units per 4x4 grow space for daytime enhanced PPFD delivery. Height over canopy should be the same as your full spectrum LED but it will not hurt the plants to hang beneath a 4x4 LED.  Time General use: Studies indicate that dosing with far red light is most effective with 4 hours on, 4 off, and 4 on. We recommend a digital wall timer, or if using TrolMaster the DSP-1 (for 110V connections) or a DSP-2 (for 240V).  Emerson Effect:  10-15 minutes after full spectrum lights are turned off. Plant Morphology Theory Plants use phytochrome to detect and respond to red and far-red wavelengths. Phytochromes are signaling proteins that promote photomorphogenesis in response to red light and far-red light. Phytochrome is the only known photoreceptor that absorbs light in the red/far red spectrum of light (600-750 nm). (source: Wikipedia) Far Red light is believed to create a competitive response in plants, pushing desirable terpene production and assisting in the formation of trichomes.   Read more about Far Red and extended spectrum in this recent release from Design Lights Consortium: Read It Here   ~Technical Specs~ Product 30W（±5%） PPF 72.1 umols/s  100-277VAC,50/60 Hz 102.3BTU IP65 44.88”x 2.24”x 1.53” 4.4 lbs Photometric Test Report Download  Product Warranty (see our warranty here) 3 year warranty

DESCRIPTION Rugged, waterproof, glass lens, 100-277 VAC. This unit is built to last.  Designed to match natural sunlight levels, the FGI UVA LED Grow Light offers extended spectrum Supplemental Blue 340-400 nm with an added PAR Booster to ensure optimal absorption of the light energy. Perfect for indoor growers and plant enthusiasts! The reason for this is that plant morphology is affected by the spectral composition of light, which means that different wavelengths of light can promote different plant growth. In particular, blue light is known to encourage compact growth and strong stems, making it an essential part of plant development. By providing plants with the same level of blue light as they would receive from the sun, the FGI 385nm UV Lightbar ensures that they can grow and develop in the best possible way. As a result, it is an invaluable tool for any gardener or plant lover who wants their plants to thrive. Science behind using UV-A supplemental energy on plants Recent studies at Utah State University have shown that plants absorb and benefit from light between 380-740NM. This research has led to the study of E-PAR or extended PAR and is redefining measurement of photosynthetic light.  Below are the spectrum charts which compare natural sunlight to full spectrum LEDs and then to full spectrum plus supplemental UV.  The result is a closer match to sunlight providing more of the beneficial blue light that plants benefit from.  Sunlight Levels of 380NM UV Natural sunlight provides plants 1.22 umols of 380nm blue energy.  Natural Sunlight Spectrum Blue Energy 1.2234 umols Typical Full Spectrum LED Lack 380NM UV Full spectrum LEDs have limited blue spectrum which peak at 460nm.   Full Spectrum LED 460nm Blue Energy Levels .0514 umols Full Spectrum LED with Supplemental 380NM UV  Adding supplemental 385NM UV creates a secondary peak of blue energy at 1.5047 umols at 12" from the canopy, roughly equaling natural sunlight.  Supplemental UV Spectrum plus Full Spectrum Blue Energy 1.5047 umols (3x greater)  Build Quality These are high quality units with a crystal glass lens cover to protect the diodes and allow for cleaning. The all aluminum frame dissipates what little heat the bar creates. At 30 watts the Lightbar sips energy too.  Spectrum Theory  Blue energy is scientifically known to help form more compact plants. More lush leaf growth, stronger and larger stems and tighter internodal spacing. We gave a prominent researcher at a major State University one our 385NM UVA Lightbars:  "Your UVA lights arrived and we have confirmed their 385 nm peak. This looks like a high quality fixture." He went on to say: "Elevated exposure to UV photons is known to enhance the synthesis of UV blocking compounds in the leaves of many species and it is reasonable to think that UV photons can increase the synthesis of secondary metabolites in plants." And further, "I expect we will find value in dosing of CSat plants with UV photons, but not surprisingly, the effects will likely interact with UV wavelength, intensity, timing of delivery, and growth stage." The UVA Lightbar fits neatly inside the frame of our Uniformity Pro LEDs as well as many other multi-bar style full spectrum LEDs. Use We recommend two of our UV-A LEDs over each 4'x4' area. The slim design allows them to be hung inside the frame of most 6 and 8 bar LEDs. Mounting height should be at the same level to avoid creating shadowing.  Control A basic digital 110V wall timer can be used, or if using the TrolMaster Hydro X we recommend the DSP-1 module for 110V or DSP-2 for 120V power connection and multiple on/off timer programming.   ~Technical Specs~ Product 30W（±5%） 20 UVA Diodes Per Bar 100-277VAC,50/60 Hz 102.3BTU IP65 44.88”x 2.24”x 1.53” 4.4 lbs Photometric File Download Product Warranty (see our warranty here) 3 year warranty
