Milliard 3in. Hydroponic/Orchid Slotted Net Pot/Cup - 20 Pack Designed with vented sides and a reinforced top rim to promote more efficient plant growth through aeration. Provides proper drainage to encourage healthy root development and a tapered bottom for easy fitting or removal of plants or pots. When a plant becomes too big for a solid pot, the roots begin to circle and choke each other. More airflow to the root zone prunes the root structure and prevents circling. The net pots allow water to drain through, so you can use them with your favorite drip or watering system. Pack of 20 3 in. Net pots.
