Lighting for Bonsai

Natural light produces a visible spectrum and is not only a source of energy, but also much needed information. Plants react to quality, intensity, duration and the direction of light. Because it is needed to aid photosynthesis necessary for germination, growth, inducing protective substances and changing from vegetative growth to fruit and flower.


The light visible to humans is 400 nm to 700 nm, a wavelength range called Photosynthetically Active Radiation (PAR) and much of the light that plants need is within this range. But will use other wavelengths for example, UV light (280 – 400 nm) is critical for optimal growth and far-red light (700-800 nm) is critical for flowering and fruiting. Known photoreceptors are most efficient in the blue and red area of the spectrum. Plants also reflect a significant part of light in the green area of the light spectrum, while absorbing a…
