I recently saw (maybe in Family Fun magazine?) an idea to use suction cup hooks to support a clear shoes hanger (the kind with pockets) to grow plants right on the window. We've had very bad luck growing plants inside, and I'm wondering if this might be a good solution. We could move it to follow the sun through the day, if nothing else. Has anyone tried this? What's the instinct of more experienced indoor growers as to the feasibility of this? I'm thinking it would be a super convenient herb garden.
