GROW STONES GS2
GS2 replaces pearlite /vermiculite/clay balls for aeriation of substrates and is one of the last years outstanding products for us. Its amazing air and nutrient holding capabilities amazed us, not only with its lightweight honeycomb white appearance but with the effect it had on turning roots bright white. This genius product is made from recycled glass & uses a minimal amount of water in its production.
