The CCH2O heavy-duty net pots were designed for optimum root penetration into nutrient solution. The reinforced ribbed collar ensures a secure fit into our Under Current? lids and offers support for large trees, while the blacked-out upper prevents light intrusion into the root zone. An inverted planting deck makes transplanting and setting water levels a breeze. Made from solid ABS, our CCH2O net pots are suitable for any gardening application. Made in California. Comes standard with all Under Current? systems.
