Bess Self-Watering Plastic Railing Planter

Made from durable polyethylene resin, this planter can withstand any weather conditions and won’t crack. And because it's HDPE, it is BPA-free and perfectly safe to contact edibles at it does not contain, nor ever leach, harmful chemicals. Additionally, the planter drainage holes allow deep plant roots to breathe and prevent stagnant water from accumulating. The best feature is the insertable soil trays that form a small pocket of air just above the waterline and below plant roots. This allows for proper aeration as roots take up water from the reservoir and completely self-watering for several days with virtually no water loss to evaporation.
