Osram has taken another step into horticultural lighting, this time targeting the residential market by acquiring a minority stake in a German startup that makes climate-controlled boxes for growing greens and herbs in the kitchen using optimized light, water, and temperature.

　　Munich-based Osram did not have to look far to find the firm, agrilution, which also operates out of Munich and which was already using tunable Osram LED technology inside its grow box.

　　The box, called plantCube, is about the size of a compact refrigerator and intelligently controls light spectrum and intensities to cultivate lettuce, basil, dill, parsley, chard, spinach, beetroot, and other produce.

　　Neither company disclosed the size of the investment, which Osram made through its quasi-independent venture capital arm, Fluxunit.
