Is Green Light Useful For Plants ?
By definition, PAR is 400 to 700 nm, in the middle of this waveband is green light, which has a wavelength between 500 and 600 nm.

What Is The Absorption Theory ?
Plants are the only photosynthetic organisms to have leaves (and not all plants have leaves). A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water and carbon

Why Is Infrared (IR) Important When Growing Indoors ?
You should always use an LED grow light that includes the infrared spectrum (IR) when growing indoors. Robert Emerson performed a series of experiments in 1957 in order to determine what wavelengths are most efficient for promoting photosynthesis. What he found was very significant, especially in regards to indoor growing and the use of LED […]
