Greens don’t have a huge root base so they can actually live in pretty shallow containers. I saw loads of people affix rain gutters to walls and fences to grow lettuce, so I figured, why not a balcony railing? I found this gutter at Home Depot for $6 and the end caps for $1 each. What a steal! I just secured it with jute rope but I might switch to white zip ties eventually. There are some baby lettuces you can’t see, interspersed with my romaine lettuces I sprouted from kitchen scraps, and some flowers for color.
I’m so pleased with this project that I’m going to go buy more guttering to wrap around both balconies.
