The original. PhysioSpec is available with RAZR and designed for rapid root development and tight internode spacing for seedling and cutting propagation, along with full-cycle cultivation of leafy greens and microgreens.
As with all Fluence PhysioSpec spectra, PhysioSpec is a broad spectrum designed first and foremost with cultivation in mind, yet has the added benefit for an ideal research and cultivation environment.
To create the most advanced spectrum for complete physiological plant growth, we had to challenge every assumption. Not only did this make the spectra better, it made it beautiful. Previously, 660nm (red) and 450nm (blue) were the most efficient LED packages, and coincided with peak Chl A and Chl B absorption areas. This led to a negligence of key photoreceptors and pigments outside this range.
PhysioSpec Indoor is a full-cycle spectrum optimized for rapid growth and complete plant development. Tailored for growing plants from propagation to senescence (germination, clones/cuttings, mothers, vegetative and flowering applications) in indoor environments. With a CRI rating of 85, PhysioSpec Indoor offers a beautiful work and research environment with vivid colors and greater contrast to study the health of your crop.
Compared to PhysioSpec Indoor, PhysioSpec Greenhouse is enriched with a higher amount of blue photons in the 400-500nm range, which are used to offset plant stretch induced by the sun’s far red radiation. As an added bonus, PhysioSpec Greenhouse offers a world-class work and research environment with vivid colors and greater contrast to study the health of your crop.
With a peak spectrum at 730nm, PfrSpec™ is designed to exclusively target phytochrome far red photoreceptors. This spectrum is widely used to target Phytochrome Far Red (Pfr) in photomorphogenic lighting applications, and it is used to lengthen the dark period to encourage the flowering process in Short Day Plants.
With a peak wavelength of 400nm, UVSpec™ is designed to provide beneficial photomorphogenic responses by creating a mild stress response in plants. As an example, when applied correctly, research shows increased THC content in cannabis plants. When applied incorrectly, research shows UV stress causes photoinhibition of chloroplasts, resulting in lower biomass production, photobleaching and death of leaves.
