CANNA Clay Pebbles 45L

Thanks to their unique structure, CANNA Aqua Clay Pebbles offer the ideal basis for growers who want to control the application of nutrients and the humidity level of their plants throughout the entire process of cultivation in a simple way. 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 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. 
CANNA Aqua Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot. They consist of different components that together form an optimum, heterogeneous structure that is ideal for root development.

Before using:

- It is important to thoroughly rinse your pebbles to remove any sand and wash off all remaining residues.

- It is recommended that you always check the pH level.Put some pebbles in a glass of water with adjusted pH to 6.0. Stir well and let it rest.Measure the pH. If it is high (7.0 or higher), soak the pebbles overnight in a solution of phosphoric or nitric acid (or pH Down liquid or powder).Then rinse thoroughly before using. - If your Grorox is neutral, wash it profusely and rinse it well.

After the harvest:

- It is generally sufficient to wash off all organic debris and rinse well.

- If needed, in case of insect or fungi infestation, it is recommended to disinfect the pebbles. To do so, soak in strong acid (or pH Down). Let them soak overnight. Rinse very thoroughly to wash the acid off completely.

Clay pebbles can be mixed with other media too.
There are several possible combinations : in hydroponics mix with pouzzolane or lava rocks; and in soil, mix with earth, perlite or vermiculite.

A great advantage to using Grorox is that, unlike rockwool, it is harmless to humans, reusable, and non-polluting. It is natural and can be used several times, from crop to crop.To discard, it can be recycled in your garden to lighten the soil.
