The UNS Glass Cup is a versatile tool for aquarists, designed for the cultivation of aquatic plants. Made from durable glass, it easily attaches to any desired location in the aquarium via suction cups. Ideal for nurturing juvenile or fragile plant species, it features a vented base to accommodate root growth. This cup is particularly useful for growing plants that need extra care or isolation from bottom-dwelling creatures, ensuring their roots can establish undisturbed.
