On Saturday Feb 12, I gave a talk with Zhenya Fomin of the Energy Coordinating Agency and a former green roofer, on the zoning, permitting, and engineering realities of green roofs and rooftop farms, at the Horticulture Center in Fairmount Park. The talk was part of the Second Saturday Gardening series, and you can check out the other great offerings here and by clicking around the Extension website here. To register for future events, call the Penn State Philadelphia Extension office at 215- 471-2200 Ext 100 or just show up.
