Group training on the production of sterilized substrates and lignicolous mushrooms

Next edition: 20th - 24th November 2017. Location: at Mycelia’s premises, Veldeken 38A 9850 Nevele, Belgium

Considering the succes of the previous editions, we are now proposing the 12th group training at our premises, which will cover all aspects of lignicolous mushroom cultivation. 

Over the years, Mycelia has acquired an excellent reputation as a training centre for mycelium and lignicolous substrate producers. Since November 2011, we have developed our group trainings on the production of sterilized substrates and lignicolous mushrooms, which cover the whole production cycle from mother culture to specialty mushroom.

The program has been developed in close collaboration with dipl. Ing. Jürgen Kynast, who has a broad-spectrum scientific background in combination with an extensive experience as a grower of specialty mushrooms. We welcome existing and would-be growers to this in-depth course. 

Program

Sunday 19/11/2017: 

Arrival at the B&B, or the hotel of your choice. 

Collection at the train station will be organized.

  • In the morning, Magda will be at Mycelia for the last preparations, while driving to the train station to collect the participants. Other pickup arrangements can be made, but should be communicated clearly.
  • In the afternoon she will be at Mycelia or in De Steenhove to prepare didactic materials and meet the participants.
