CU-35-680 Delivering high Photosynthetic conversion for Photosystems I
In nature, sunlight contains almost as much far-red light (20%) as red light (21%). The top of the canopy is most exposed to sunlight and readily absorb’s red light while reflecting or transmitting most far-red light.
As a result, leaves lower in the canopy have less red light available and receive a higher proportion of far-red light. This relatively low red to far-red ratio triggers stems to extend and leaves to expand to intercept more sunlight. Supplemental LED lighting can be utilised to trigger this response.
With the stretching response of plants to far-red light, grow areas can benefit from more compact growth but should be done so cautiously So when adding far-red to your lighting regimen, It is important to consider the ratio of far-red light to other wavebands, and the plant variety when adding far-red light to your lighting recipe.
Red/Far Red it plays a critical role in photosynthetic efficiency. The “Emerson Effect” is the notion that two photosystems, one that is most sensitive to 680 nm photons and one to 700 nm photons (and far-red light up to 850 nm), work together to optimise electron transport and photosynthetic rates
