Keeping our beautful "Direct Mount Laguna" window box planters looking vibrant with flowers is as simple as keeping the root balls of the plants supplied with water. This challenge is "no sweat" with our Laguna boxes packaged with removable self watering reservoirs. Designed to deliver water up to 9" for the reservoir's perimeter plus a low profile design that maximizes vertical planting space - these self watering planter solutions are up to the task. For 48, 60 and 72" boxes, there are two reservoirs, each with their own fill tube for easy access. Depending on your climate or your out of town travel plans, these hard working reservoirs easily "plant sit" while you don't have to.
