-shoot correlative inhibition, shoot removal leads to 1) increased light intensity lower in the crop canopy; 2) changes in the light spectrum (higher intensity of red light compared with far-red light, resulting in a higher red:far-red ratio); and 3) changed source

past few decades it has been demonstrated that discrete sections of the electromagnetic spectrum tickle specific photoreceptors that then ignite plant sensory networks, ultimately resulting in a change in content, stature, or behavior. These concepts

cropping cycles of ornamental plants grown in controlled environments. One approach to enhancing growth is to include far-red light (λ = 700–800 nm) in the spectrum because 1) far-red light can trigger a shade-avoidance and/or acclimation response

illuminance, a measure of radiation expressed as the PPF intensity from 380 to 780 nm [the photosynthetic radiation spectrum ( PAR )], is often used in horticulture for determining the sufficiency of light intensity for proper plant cultivation. Multiple
