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.
Whether you are targeting the emerson effect, or tweaking plant morphology, or simply looking to add efficient and inexpensive PAR to your grow, our Far Red bars are the one chosen by thousands of growers worldwide.
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.
