How grass grows, how light works and how to read a grow light spec sheet. Written by the people who build the technology.
Light science
Dynamic Light Spectrum explained
Sunlight changes all day long, in strength and in colour. A fixed LED spectrum stays the same from the moment it switches on. Dynamic Light Spectrum (DLS) lets you change the light during the day, so your grass gets what it needs at each moment.
Grass does not only use light as food. It also reads light as information. The colour of the light tells the plant what time of day it is, whether it is in the shade and how it should grow. A good grow light strategy uses both.
Grow light spec sheets are full of terms and numbers. This article explains what they mean, which ones matter most, and how to compare grow lights fairly.
A grow light is only as good as the light it spreads evenly over the grass. If some areas get much more light than others, the pitch grows unevenly. Light distribution is one of the most underestimated parts of a grow light system.
For years, stadium grow lights used HPS SON-T lamps: the orange high-pressure sodium lamps many groundsmen know well. Today, LED has taken over. This article explains the differences and what they mean for your pitch and your energy bill.
Two grow lights with the same wattage can give very different results on the grass. The difference is in the LEDs themselves, how they are cooled and how they are controlled. This article explains what makes an efficient grow light.
Healthy grass needs five things: light, temperature, water, CO₂ and nutrients. If one of them falls short, growth and recovery slow down, no matter how much you give of the others. Good turf management keeps all five in balance.
Light is only half the story. What happens in the root zone decides how well grass can use that light. Soil sensors on your grow light rig show you water, salt and nutrient levels in real time, right where the unit stands.
