Dear Uta,

I am sorry to correct you but Seramis is far from being broken brick. I visited the factory a few years ago. Seramis is produced from a special clay, mixed with a foam component and burnt at high temperatures. Therefore it is low in salts, has a neutral pH and a sponge structure with open pores (in contrast to clay pebbles for hydroponics which have closed pores).

Broken brick can contain high amounts of salt, high amounts of lime with a resulting high pH. Therefore broken brick cannot be recommended for the pot culture of Cyps. It might however be possible to mix it in beds in the garden.


Best regards

Michael
