Do LED grow lights provide enough heat in a greenhouse?

Tunable LEDs are all the rage for dialing the right light recipe. But one Belgium tomato farm wasn’t so sure they would be physically warm enough. So the growers took extra steps.

Tunable LED lights are gaining acclaim for providing just the right spectra to suit the varying wavelength preferences of different indoor crops.
