Mycorrhiza started Urban Rooftop Beekeeping

I visited Malmö for few days and passed Mycorrhiza's urban kitchen garden. They are doing great work. I was amazed to see them starting with urban roof-top beekeeping on Malmö roofs :) so cool. Will see if I can help them build a few inexpensive African Top Bar Hives this winter :)
