Clay pebbles, also knows as Hydroton or Hydrocorn are made by heating clay at high temperatures causing it to expand. This produces a roughly finished and highly porous medium excellent at retaining moisture, trapping air, and oxygenating any nutrient solution flowing over it. The uneven exterior of hydroton creates the ideal surface for roots to bind to and promotes the colonization of beneficial bacteria. The honeycomb-like interior is great at retaining liquid solutions. Even better, clay pebbles are pH stable and completely inert once initially rinsed!

Growstones are an environmentally friendly and sustainable soilless option made from recycled glass. Growstones are generally used in one of two ways. The first and most basic way to use growstones is as a stand alone hydroponic growing medium. The second way is to have growstones used as a soil enhancement to aerate container gardens, potted plants, and flower beds.

Growstones are available in several particle sizes depending on your specific application. Smaller stones are ideal for propagation mixes, medium stones are best for soil enhancement, and larger stones are perfect for most hydroponic systems.

Hydroton and growstones maintain their structural integrity over time so they can be reused for years, reducing costs, and waste. Just rinse and sterilize between crops!
