Because every grow setup is different, results can vary based on experience, environment, and growing methods. While many growers have great success with reusable grow mediums, we can’t guarantee identical results for everyone. If you’re new to reusable mediums, we recommend starting with a small pack to test them in your setup before purchasing in larger quantities. This helps you dial things in and grow with confidence.
