Whistler,

Are you thinking about hanging these on the walls rather than at the edge of the roof to grow the lettuce? I've seen this, using the widest available gutters....and mostly plastic ones. I've also seen them mounted at different levels on fences for vertical gardening in small spaces. As long as you cap the ends you should be good.

But the plastic could break down over years of exposure to UV rays.

added - You were obviously adding the above post when I wrote mine. Should work on the railings with no problem. But use wide ones.
