Product information

Euro Pebbles is a high-quality inert hydroponic substrate. The material is based on pure, salt-free clay that is baked in an open oven to produce the characteristic irregular granules. Euro Pebbles has a broad range of applications because the user can determine the nutritional value. This substrate is suitable for various cultivation methods and specifically suited to recirculating systems. Euro Pebbles is washed. Euro Pebbles produces the highest yields in combination with Plagron Hydro A&B and the additives from Plagron.

Euro Pebbles have already been rinsed. However, dust is formed during transport, so it is best to rinse Euro Pebbles before use. You will also want to give nutrient feed water with the correct EC and pH value before planting.

You can use Euro Pebbles for many years. To do so, first remove any old plant debris. Next, soak the Euro Pebbles for 24 hours in a solution of Pure Zym and water with a pH value of 5.5. Then rinse them with a nutrient solution of 1 ml Hydro A&B per liter water. Make sure this water has a pH value of 5.5.

It is almost impossible to give too much water on Euro Pebbles, as the gaps between the pebbles are very large. Instead, make sure you give enough water. We recommend watering at least twice an hour, including during the night. Use a timer on your irrigation system for this.

Pure and salt-free clays are used as raw materials in Euro Pebbles. These are baked in an open oven to their characteristic irregular shape. This makes the final product cleaner and firmer than comparable products.

Euro Pebbles can be used as a substrate for hydroponic growing. You can also mix the Euro Pebbles with a peat substrate, which will improve your drainage. Do you prefer growing on coconut, and would you like to add Euro Pebbles for better drainage? Then use our ready-made mix Plagron Hydro Cocos 60/40 (60% Euro Pebbles and 40% Cocos Premium).

Euro Pebbles stimulates fast drainage. This means the chance of over-watering is very small. Because there is a lot of space between the grains, there is a lot of oxygen available for your roots. This space also ensures that the roots can grow freely.

When rinsed, Euro Pebbles forms a clean and pure substrate that does not release organic substances. It does not pollute pipes and is therefore ideal for recirculating systems.
