Unlock the benefits of Under-Canopy Lighting

Under-Canopy Lighting: Boost Yields, Bud Quality & Color

Under-canopy lighting transforms indoor horticulture by actively delivering light to the lower parts of plants, which are usually shaded and underexposed. This method ensures better light penetration to areas that traditional overhead lighting cannot reach, promoting healthier growth and more uniform development throughout the plant, ultimately boosting both yield and quality.

This innovative lighting strategy employs scientifically designed lights placed beneath the plant canopy. These lights target areas that traditional overhead lighting systems cannot reach effectively.

The science behind sub-canopy lighting centers on the principle of photosynthetically active radiation (PAR). PAR is crucial for plant health as it involves the wavelengths of light that plants use for photosynthesis.
