Arbor Originals Decorative architectural arbors and brackets instead of window boxes? Maybe just a shallow pan so the wood doesn't look dirty?? What about the hurricane shutters though? would they still fit???
Plastic Bottles instead of Pea Gravel Pea gravel and pebbles can weigh down window boxes. Empty water bottles are a lightweight option. Place rinsed bottles inside the planter and add soil on top of them. The space between the bottles will allow proper drainage without the extra weight.
Plant your edible goodies in a window planter, and you can snip off what you need for salads and cooking and then watch them magically regrow. http://www.ehow.com/ehow-home/blog/no-garden-no-problem-create-a-self-sustaining-decorative-and-edible-windowsill-planter/?utm_source=pinterest.com&utm_medium=referral&utm_content=blog&utm_campaign=fanpage
