CANNA AQUA Clay Pebbles is a superior expanded clay medium. The large and porous pebbles make them a great base for growers who want to control the supply of moisture directly throughout the growth process.
They are inorganic, have a neutral pH and consist of several fractions which create a heterogeneous texture for optimum rooting. CANNA Aqua Clay Pebbles give you the basis for optimal growth and flowering.
CANNA Aqua Clay Pebbles deliver a high pore volume with high air content; this promotes strong roots with a firm hold. They are manufactured from superior clay with a low content of soluble salts. This makes them especially suitable for growing in re-circulating systems, like the rest of the CANNA AQUA line.
They also work very well in Run-to-Waste systems and are perfect to improve soil drainage.
