Expanded clay pebbles for use as a standalone hydroponic or semi-hydro substrate. Useful to anchor plants that live in vases and provide weight.
Please note: we do NOT recommend this for use in your soil mix due to the round shape and fine pores. It does not help much with drainage. If you're looking for something to increase weight and drainage we recommend pumice or lava rock. Just looking for drainage? Check out our rice hulls and coco chips :)
