On november 8th 2017 The Hessischer Pilztag took place in Kerns in Switzerland. It was a very well-attended program with over more than 100 participants from all over the World. There was a company visit to Kernser Edelpilze. Where Sepp and Patrick Häcki gave a tour in the new substrate company where they produce on a weekly basis 250 tons of substrate for mainly pleurotus eryngii, shiitake and pleurotus ostreatus. Currently they produce about 100 tonnes of substrate in 1.3kg bags of which 40% is for their own farm and 60% is sold to other customers in Europe.
