Hydrofarm gray dirt pots offer value & versatility for outdoor use or as part of hydroponic growing systems. Featuring porous breathable fabric that is made from 100% recycled water bottles, these planters allow your plants to thrive by promoting exceptional root health & vigorous plant growth. The soft-sided construction allows the planter to conform to your terrain, making it the perfect choice for all growing areas. Gray dirt pots are stronger than similar products, with reinforced seams & stitching. They are non-degradable, so they will hold up for multiple growing seasons.
