      Comments about 31" Self-Watering Windowbox:

      We hung two of these on the chain link fence last summer and loved them so much that we are adding another one for this summer. The plants never looked better since they are now getting sufficient water. I found that I only needed to refill the water resorvoir once a week. Definately a good product!

          Ordered them for Christmas, so haven't used them yet, but very excited to give them a try. All things I've bought from Gardners Supply have been quality items, so no doubt this will be too.

            It makes maintenance much easier, plants have a more even supply of water and grow better than with ordinary planters

              Have put 5 of these across 45 feet of windows on back of house ... wonderful value for the price. They add interest & color, and living in FL, biggest problem is ALWAYS keeping soil moist ... no longer! I also have self-watering vegetable boxes and am SOLD on the concept.

                  I bought 2 of these boxes last year and loved them so much I bought 2 more this year. No more asking neighbors to water my plants when we are away. These boxes hold enough water to keep my flowers moist for up to 2 weeks. By putting the fertilizer in the water reservoir also it is dispensed gradually.

                    One works beautifully- -holding water. The second one- -the water drains. Will check it out when I change the flowers.

                        I have the box attached to a deck rail outside my kitchen window so I can enjoy the flowers every day. The plus is not having to worry about watering when we're away.

                          I bought two of these at the beginning of the summer for our lakeside cottage. The water-fill tube system and large reservoir kept the plants from drying out when we were not there to water. All plants are healthy and lush. These window boxes perform much better than the ones I had been using for the past several years.
                          The bronze color matches the cottage perfectly!
