living roof and container gardening

I just read a post on this site by Sunflower, who wants to green her home. I love this idea, and I hope people know about the Learn section we have on this site, we have a section all about how to green your home.

I especially love the living roof idea, if anybody out there has tips or DIY instructions for how to make a living roof or container gardening (for those of us in apartments) Please post them to this site and I will add them to the Learn section!
