Good permeability: these net cups feature a slotted mesh design to promote efficient plant growth through improved aeration. The net pots have holes in the bottom to encourage healthy root development with even drainage, allowing roots to grow naturally downward or outward for larger, stronger root systems. The comfortably sized lip on top makes the hydroponic cups easy to handle, lift, and transport. The slits support robust root growth and make the baskets easier to clean. Made of durable plastic, these net pots are reusable and resistant to cracking. The wide lip ensures secure handling and stability when placed in larger containers. Versatile use: suitable for hydroponic systems or soil-based applications; can be used with clay pebbles, lava rocks, pumice, vermiculite, and other growing media.
