This is an interesting question. In order to answer it you have to realise that infrared light is further to the right of the visible light spectrum that turfgrass generally uses but that Infrared waves can also affect how plants grow.
An “infrared heater” converts electricity into light and heat as well as emits infrared light.
Turfgrass cannot make use of infrared light for photosynthesis because they lack a pigment which can utilise light with that wavelength.
Plants grown in light that is too red may seem spindly and long-stemmed. Too much infrared light, especially in the far red end of the spectrum, may actually damage plants.
