Greenlab installed a demonstration green roof on the Storage Container at the Gowanus Canal Conservancy Salt Lot in the fall of 2011. We wanted to update on the progress since it is now the second season and very active! The roof is not irrigated but the bed is designed to hold water and slow release through the gabion - wood edge. The grasses and forbes did not survive through the first season, but the sedum are absolutely thriving! The sedum roof and honeybee hives at the Salt Lot are mutually benefiting each other - we love the fact that the green roof + gowanus compost + gowanus bee hives are making a complete cycle!
