    I would always have trouble keeping up with plants and their need for water in the hot summer months, plus I wanted something attractive to put on my kitchen window sill! I achieved both with this wonderful planter!!!

      I looked a long time to find deck rail self watering planters AND brackets that were white strong and had assembly options to make my boxes sit level. I love these! They come with brackets that are the best I've found. Great value, plus the planters hold lots of plants. I used the self watering soil and my plants look amazing and I only water about 1/week. Highly recommend!

          We are so happy with this window box. It is on our outdoor shed at some distance from water source so having this self-watering is not only handy but really works. The lobelia are doing better than any other year.

          I love it for the looks, exactly what I need under a small garage window. Husband hates it for the difficulties he had attaching it to the window and siding without causing damage to either.

              These planters have been under my front windows for 20 years. They are in full Southern sun, and the water reservoirs keep them healthy all summer. Recently I bought another one for a back window, and the new ones are of the same quality. Very attractive.

                    The instructions say to drill the bottom with a 1/8th in bit. It should be much larger because drainage is a problem. Small plants drown. I would highly recommend you fill it with larger flowering plants. Not good for starters. And drill a much larger hole in the bottom.
