Please note that our new shipment are irregular-shaped clay pebbles. These are not round, and may be grey or red. Why? I decided to bring y’all a way lower price!
Expanded clay pebbles for use as a standalone hydroponic or semi-hydro substrate. Useful to anchor plants that live in vases and provide weight.
We do NOT recommend this for use in your soil mix due to the rounded 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 :)
