?Lowers Heating Costs for Building Above
Even the most efficient LED lights generate waste heat,which means that they heat up the farm,and for most modern indoor farms that's a major issue because not only energy is lost through lighting,but it's also required to cool down the farm. (4)FF.Besides,people are working on ways to recycle the waste heat in order to help heat the building above and reduce its energy.
