Large Round Crate. Crate Size: 10"dia.x 7.5" deep. Tricker’s black aquatic planting crates are designed to be specifically used in the water garden to promote and successfully grow your water plants. They all have "lattice" sides which will allow the roots to penetrate into the surrounding water. This feature allows the exchange of gases and water nutrients to enter the aquatic plants. In addtion, these crates have easy Carrying Handles and Lifting Slots. These special features make it easier to handle, not only to carry to your pond but arrange in the pool! Better than the solid sided tubs or other containers.
