Published in today’s HortiDaily, there is a very interesting story about greenhouses that are using pink glass to produce energy.

Michael Loik, of the Loik Laboratory in the Environmental Studies Department at the University of California, Santa Cruz explains why the choice of pink: “That is because of the dye that was selected to allow the red wavelengths of sunlight to be able to pass through. Colors that are not absorbed by the dye are reflected or transmitted. In this case, the dye absorbs green and some of the blue. The blue that is not absorbed, as well as the red wavelengths of sunlight, are transmitted or reflected (red + some blue = magenta).”

Beyond energy production, commercial trials have increased cucumber yields by 10% increase and lettuce / herb yields by nearly 50%. There is also a reduction in water usage due to lower temperatures.

These greenhouses can be used anywhere, so you may see a pink greenhouse in your area soon!
