Home Roof Gardens in Chicago
“This past summer, my friends (Art and Heidi) and I tried to grow heirloom vegetables on our respective rooftops in Chicago using homemade Earthboxes. Heidi would come over every few weeks and take some photos of my plants, which she then sent me along with some shots from their roof garden.
“We’re trying to figure out how to automate the watering of all those tubs on my garage roof without spending a lot of money. Here’s what I’ve got so far: Out of a reservoir kept full with a Hudson valve, I’d run supply lines to each of the boxes. If I suck all the air out of these lines, the siphon/water level effect should keep all the tubs watered as long as the vacuum seal isn’t broken.”
