Kool Ray™

Spray-Applied Semi-Permanent Liquid Greenhouse Shading Concentrate

Since 1953, Kool Ray™ Liquid Shade has been helping greenhouses keep their cool. Kool Ray Liquid Shade is a shading concentrate that, when diluted with water to a desired shading density and applied to the external glazing of a greenhouse, provides a cost-effective, easy-to-use alternative to mechanical greenhouse shading and ventilation systems.

Kool Ray’s bright white formulation effectively lowers the inside greenhouse temperatures during the peak growing season while allowing the growth wavelengths of light to pass through on their way to your plants. Once applied, Kool Ray’s environmentally friendly ingredients will slowly wear off during the growing season (weather permitting) gradually allowing for increased light levels as the amount of daylight decreases. Kool Ray works best when spray applied, but it can also be applied with a brush or a roller.
