- With the clay granules you have an additional water buffer. With the clay granules and the urban Chili tub, you only need to water once a week.
The clay granules act as a membrane between soil and water therefore you can also give 5 liters of water. A short break is thus easily possible. And the growbox just keeps going.
Best place in the pot 1 piece of kitchen roll so that the clay grains do not fall out. Divide the delivered sack of clay granules evenly on all 4 pots.
