Supplemental lighting

"What would you say is the biggest benefit of supplemental lighting in greenhouse growing?For me, the use of supplemental lighting in greenhouse growing has its largest impact concerning carbon footprints. Using the greatest light source in the world (the sun) for the heavy lifting and just supplementing a few hours a day when sunlight intensity is low is a much greener way of producig crops than with straight indoor growing. Also, with this method, you can produce quality crops all year round with lower production costs."

The demonstration greenhouse should prove that CPV glass is ideally suited to this type of project.

For this application the focus will be on functionality, aesthetics not so much.

I like the idea of rooftop greenhouses which take advantage and of what is otherwise wasted space.
