Only the best clay from Germany's Westerwald is good enough for SERAMIS®.
This natural material is refined into granules with fine pores that can store water to be later released to the plant as needed. SERAMIS® is able to transport oxygen to the roots better than soil and maintains its volume for years. Plants in SERAMIS® need to be watered three times less frequently than those in soil. A special moisture indicator reveals if there is still enough water in the pot.
