Reusable for three to five years, these degradable Root Pots promote vigorous root growth by allowing roots to breathe. They work great with drip lines and hydroponic flood trays. Unlike plastic pots, Root Pots are designed to break down after multiple seasons of use. Root Pots are not tapered like plastic pots, so they stand up well to strong winds and heavy harvests. Works great for hydroponic or soil gardening.
