Growing Power: An Urban Farm & Community Center

Even though this is supposed to be a blog about my experiences in Ojai, I recently had an earth-bound experience here in the Midwest and of course, this distinction of place is just silly, because the earth is where I am, whatever the latitude and longitude but my poor little brain likes  categories. Last Saturday, my friend Dorie and I drive to Milwaukee to visit Growing Power, a well-known urban farm and community food center. Founder Will Allen has been featured in the popular film Fresh. An ex-NBA player and son of Southern farmers, Will has created an amazing venue that is on the verge of a huge vertical expansion in situ that will include, among many other cool projects, a culinary school. Currently he grows tons of greens and farms fish 365 days/year in a series of greenhouses that were originally the site of Milwaukee's commerical flower industry in the 1930's. With a staff of 35 and over 200 volunteers, Growing Power produces food for schools and restaurants, a local food coop and farmers' markets. They also have goats, chickens, turkeys and mushrooms!
I especially loved the aquaponics. Tilapia are being farmed in a four foot deep plastic-lined trench, which capitalizes on the geothermal effect of the soil, below trays of watercress, a popular microgreen destined for area restaurants. Water is pumped through the watercress for filtering and back to the fish while also fertilizing the watercress with the fish waste. Worm casings from the vermiculture (worm composting) are also fed to the fish. At Growing Power they take some of the partially composted wood chips and food waste material and give the worms a crack at it which they work through much faster that through fresh foodwaste which is what I have been accustomed to feeding them. Then the worms very quickly produce the rich fertilizer-grade compost that can be diluted for a soil additive or sold in bags as a powerful fertilizer. This answered my question about what was really so great about worms since mine took a very long time to digest what I gave them. The tilapia ponds and watercress operation runs the length of the greenhouse and are expected to produce 30,000 fish!
