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
