GreenGrow 5-8mm Expanded Clay Granules For Hydroponics - Excellent Aeration And Water Tank

Expanded clay granules are an inert planting substrate designed for hydroponics and traditional pots. Tough, lightweight and non-toxic, these granules support healthy plant growth without harming them or the fauna in the spaces where they are used.

• Granule size: 5–8 mm, providing an optimal distribution of oxygen and water in planting systems.
• Material: natural expanded clay, manufactured at high temperatures for a durable porous structure.
• Packaging: presented as 1 L volume for hydroponic planting substrate.
• Aeration and retention properties: the porous structure ensures excellent root aeration and acts as a water reservoir to balance moisture.
• Applications: main substrate in hydroponic systems, drainage material for pots, heavy soil loosening and decorative ground cover.
• Safety and durability: natural, non-toxic, odorless and potentially reusable; does not lose its properties over time.
• Handling: easy to use and clean, ideal for taking care of plants in homes, on the balcony or terrace.
• Production note: size and weight may vary slightly due to manual measurements; the product is shown per litre, not per gram.

This expanded clay substrate provides an optimal balance between water retention and root aeration, which supports vigorous plant growth, reduces the risk of root rot and supports the flow of nutrients to the roots. It is suitable for houseplants, aromatic plants and urban gardening projects, facilitating drainage in pots, improving soil texture and adding a decorative selection to the surface of the substrate. In hydroponic systems, granules act as a stable planting medium, helping to distribute nutrients evenly and maintain a healthy root environment. Their possible repeated use reduces waste and contributes to less stressful plant care.
