Super heavy duty designed to be re-used. Wider hole spacing for better root aeration. They feature a heavier-gauge and more dense plastic netting, which is more resistant to cracking & breakdown than regular net pots. These Heavy-Duty Net Pots are perfect to use in almost any kind of hydroponic system, including ebb/flow (flood & drain), drip & NFT. Made with recycled plastic in Humboldt County.
