Overview 

The FGI 730nm Lightbar is the best dedicated far red LED grow light on the market today. It's rugged all aluminum body dissipates heat well. A crystal lens covers the diodes making the waterproof. A little overspray won't hurt at all. Built for difficult indoor grow rooms, this light can be bumped around and moved easily. 

Our dedicated far red led grow lightbar boosts light levels in veg and/or flower. Adding two of these bars to your 4x4 grow space will lift PFD (photon flux density) 10%.

(Quick note: This 730nm energy is outside of 400-700nm PAR. A standard quantum PAR meter cannot measure this additive energy. And neither can a Lux meter. We recommend using an Apogee MQ-610 extended PAR meter for checking light levels with supplemental far red or UV spectrum).

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. 

Use this energy in flower and you'll see earlier trichome development. 

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.

If you are only after the Emerson Effect one of these bars will help your plants to sleep over a 6'x4' area. 


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. 

Description 

At 30 watts of input power they sip energy too, while emitting a strong boost of red spectrum. 

Each Lightbar is prewired with an 8’ cord and 110v plug and are stand alone. Separate timer/switches are recommended to control the light interval.

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.

Emerson Effect

The Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to light of wavelength 680 nm (deep red spectrum) and more than 680 nm (far red spectrum). When simultaneously exposed to light of both wavelengths, the rate of photosynthesis is far higher than the sum of the red light and far red light photosynthesis rates. The effect was early evidence that two photosystems, processing different wavelengths, cooperate in photosynthesis.

Dr. Robert Emerson, who taught at the University of Illinois, discovered that light on the far end of the spectrum, infrared light, boosted photosynthesis when combined with other wavelengths. Emerson’s primary observations included:

There are two chemical procedures that contribute to photosynthesis. These processes are hastened, and are more efficient, when the plant is exposed to far-red and infrared light.

The plant protein phytochrome absorbs red, far-red and infrared wavelengths; this protein is responsible for regulating flowering.

Modern indoor grow professionals have taken Emerson’s studies and applied it to their own gardens, finding that infrared light can also result in strong stem growth, tighter node formation and boosted flower yields.
