2 Dans Toiling at Twilight; Thankfulness

Dan and Dan were recently improving the insulation on one of Cultivate the City‘s rooftop greenhouses ahead of the winter.

This greenhouse hosts a hydroponic system with 25 vertical zipgrow towers; stacked-pot drip-line vertical hydroponic systems; and an aquaponic system we will be overhauling in the months ahead.

Controlled environment agriculture gives us the ability to produce food in the middle of Washington, DC in the middle of winter — as opposed to shipping all of our fresh produce thousands of miles for half the year. And vertical growing gives us the ability to produce large quantities of food relative to square land area.

The problem: our nation’s economic structure. We do not charge the true cost of carbon. Big companies have an implicit subsidy to use as much carbon as they want to get their food here from across the planet and compete against efficient local growers. Sad.

So this year I’m thankful for Dan, Dan, and the rest of the Washington, DC urban agriculture community!
