Natural root development: the net pot has holes in the bottom to encourage healthy root growth with even drainage, allowing roots to grow downward or through the sides for larger, stronger root systems. Ergonomic design: a comfortably sized lip on the top makes the hydroponic cups easy to handle, lift, and transport. The slits support bigger, healthier roots and make cleaning easier. Durable and reusable: made of sturdy plastic material, these net pots are reusable and resistant to cracking or breaking. The wide top lip ensures secure handling during use and transport. Versatile use: suitable for hydroponic systems or soil-based growing. Can be used with growing media such as clay pebbles, lava rocks, pumice, or vermiculite.
