Philips light recipes capture all the elements of lighting that steer plant growth. They are the result of hundreds of trials and projects between Philips Horticulture Lighting, growers and researchers to investigate how LED grow lights affect various crops and growing phases of plants. Today, we offer a wide array of light recipes, based on proven results for specific varieties, growth phases and cultivation set-ups. From tissue culture, propagation and seedlings to young plants, potted plants and high wire vegetables.
The amount of light shed on a plant (in µmol/s2). Some crops like cucumbers love high light levels, while others prefer lower light levels. Our light recipe sets the optimum light levels for specific crops.
The spectrum is the range from ultraviolet to infra-red that influences plant growth. Plants are particularly sensitive to a mix of red and blue light and each light recipe specifies the color of the LED lighting.
Uniformity is how evenly the light is spread across all the crops, not just the ones in the middle. Uniform light ensures uniform plant growth and makes automatic harvesting possible.
A head of lettuce needs about 14 hours of light per day, while basil prefers 20 hours of light a day. And that may change across the season. A light recipe specifies when to turn the lighting on and off to get the best results based on your geographical location.
