11-hole x2 hydroponic grow tubs with air lines and air stones.

These two hydroponic growing systems feature 11 planting holes each. And one has modified holes to accommodate larger cups for plants needing more root development above water level. White plastic containers with included tubing and aeration components. Approximately 40 cm x 25 cm x 15 cm or 15.7" x 9.8" x 5.9". I used for plants crowded and need for higher lighting from Aerogarden started systems.
