CANNA Aqua Clay Pebbles are baked clay pellets that form an ideal substrate for use by experienced growers. Aqua Clay Pebbles are ideal for growers who want to control the application of nutrients and the humidity level of their plants throughout the entire cultivation process. CANNA Aqua Clay Pebbles are manufactured from special types of clay that have a low soluble salt content. Because of this, they are particularly suited for use in closed hydroponic cultivation systems. CANNA Aqua Clay Pebbles have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well. Strong roots mean bigger yields. Aqua Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot.

Also known as hydroton, LECA balls, lightweight expanded clay pebbles and hydro corn, Hydro korrels form an ideal growing medium for hydroponics and aquaponics, and aid in soil-grown crops and house plant cultivation.

Ranging in size from 8 mm - 16 mm (1/3 - 3/5 of an inch), the porous pebbles hold plants in place when used as a growing medium, and allow for excellent oxygen penetration and moisture retention and release.

Clay pebbles may be used as the sole growing medium for plants in a hydroponic or aquaponic system, or used as a soil additive for soil-grown crops, breaking up heavy clay soils and helping with retaining proper moisture levels.

Clay pebbles may also be used as a decorative top dressing for landscaping and for house plants, where they will help to slow moisture evaporation.

Composed completely of clay that's heated in high temperatures in a manufacturing furnace, expanded clay pebbles are sterile and free of phytotoxic materials.
