I decided to take another day off from work to work on my green roof garden instead and I am completely sore today! It was a perfect day for it--nice and cool. I had Anwar from the neighborhood help me and it took us all afternoon to lay down the root barrier and put together 96 trays of the GreenGrid system. Bringing up these 40-lbs soil bags to the roof was a giant task itself. That took us all morning. We haven't yet put in the plants--sedum kamtschaticum--in the GreenGrid trays but we'll do that tonight. Now that it's all laid out, it looks really nice. Maybe I'll save a couple of trays for an herb garden or something. I guess the possibilities are endless.
