Product description
Boasting the largest 8 mm–16 mm granule size, these clay hydroponic pebbles create generous air pockets that drive vigorous root growth and optimal nutrient uptake. Their substantial size offers exceptional stability for larger plants and heavy fruiting varieties, ensuring your setup remains clean and clog-free throughout the growing cycle.
Manufactured from premium natural clay, this medium balances superior drainage with excellent aeration, helping to prevent root rot and maintain an ideal environment for indoor and outdoor hydroponic systems. The inert, neutral-pH composition guarantees no chemical interference with your nutrient solution, while the durable, reusable nature of the pebbles delivers long-term value season after season.
