Hydro granules for indoor and outdoor plants.
Put the grains at the bottom of the pot or window box so that the excess water rest in the grain.
This prevents that the plants are standing in too much water.
The plants can then also take back the water from the grains.
Available packs of 60 litres (€ 15.50). 25 litres (€ 7.00) and 1 litre (€ 1.00).
