Clay Pebbles
Clay pebbles have long been a popular choice for hydroponic growing, offering an ideal substrate for plant roots. Their porous surface helps retain ample moisture, while their rounded shape promotes excellent drainage and ensures plenty of airflow around the roots. In recent years, the quality of clay pebbles for cultivation has seen significant improvements. For instance, Gold Label Hydrocorn is RHP-certified, which guarantees that it meets strict standards for safety, reliability, and consistency in crop production.
