Liaflor Hydroton - 8/16MM 5 Litres

Liaflor Hydroton is an expanded clay substrate for hydroculture and professional hydroponics, designed to support healthy plant growth with steady moisture buffering and root-zone aeration. This mineral growing medium offers a clean, durable foundation for growers who want a consistent, low-mess alternative to traditional potting substrates.

Liaflor Hydroton is made from natural Liassic clay that is baked in a rotary oven at approximately 1,200 °C, then expanded and sieved into clay granules. That high-temperature process creates a germ-free substrate that is chemically and biologically neutral, helping keep the root environment stable and predictable. It’s also frostproof and non-flammable, which speaks to the material’s toughness and reliability in day-to-day horticultural setups.

The structure of Liaflor clay granules is defined by countless air gaps throughout each piece. Those air gaps give the product its light weight while supporting adequate aeration around roots. At the same time, the high baking temperature makes the granules strong and stable, so they retain their shape even when wet. That shape stability helps maintain a consistent root-zone structure instead of breaking down into compacted fines over time.

Moisture handling is another key reason growers choose an expanded clay substrate. Liaflor Hydroton is described as providing ideal drainage for indoor and terrace plants while also absorbing excess moisture, storing it, and releasing it again when plants need it. This moisture buffering can help reduce the risk of waterlogging and mould in the root area, while also helping minimize the chance of the growing medium drying out too quickly. For propagation shelves, indoor plant racks, and hydroculture containers, that balance of drainage and water holding can support steadier root conditions with fewer swings.

Liaflor Hydroton is a good fit for gardeners who want a hydroculture substrate that stays clean and odour-free, supports prevention of soil pests, and promotes healthy plant growth through a well-aerated, moisture-buffering structure. If you’re setting up an easy-to-maintain hydroponic project or building a dependable indoor planting system where consistent drainage and adequate aeration matter, this expanded clay substrate is a practical, professional-grade choice.
