Holds you plants in place with little or no substrate, sand or gravel.

To use, simply slide enough stems of the bare root plants into the ring to maintain a secure hold. If necessary, affix smaller stem numbers with plant glue. Alternatively, you can wrap, stabilize or plug extra space with sponge, foam or rockwool fiber, as found in potted plants, to keep them in place. 

The porous ceramic rings also play a vital role in maintaining a healthy environment by holding beneficial bacteria that help with biologic processes. These rings are made of high-quality ceramics that are fired at high temperatures, resulting in a strong and durable product.
