Good permeability: these net cups feature slotted mesh design to promote efficient plant growth through aeration. Growing by own way: net pots have holes in the bottom for healthy and even drainage, allowing roots to grow naturally downward or through the sides, supporting bigger and healthier plants. Comfortably sized lip on the top makes the hydroponic cups easy to handle, lift, and transport. The design also allows for bigger, healthier root development and makes the baskets easier to clean. Wide range of applications: these hydroponic containers are suitable for use in aquaponic and hydroponic systems with orchids, tomatoes, peppers, and more. Ideal for home gardens, balcony gardens, soilless cultivation, and liquid-based growing methods. Designed for hydroponic plants: the wide-lip round net pots are compatible with various soil-based and hydroponic media such as expanded clay, lava rock, pumice, and rockwool. Roots can easily grow through the sides and bottom of the cup.
