For those who don't know, Boulder has a bunch of land outside the city that is designated openspace/'farm' land. Being from the midwest I always sort of laughed at these land parcels being called 'farms' since economically it really can't be farmed outside of selling niche products at affluent farmers markets. I am glad to see that Boulder is finally letting the land be used for something more productive.
And this is a very cool idea. My family grew strawberries in eastern Colorado for a few years and one of the big problems was the extreme sun. In order to extend the growing season we used low tunnels to shield to plants from frost. However, the low tunnels during the peak summer months would act like a lens melting irrigation lines and even damaging produce.
