Mushrooms (Agaricus bisporus) are produced in a growing room with a heating, ventilation and air conditioning (HVAC) system. Cultivation is cyclical and consists of several successive phases. Every production phase has different environmental requirements. Microclimate is a system with multiple input signals (e.g. control signals of the solenoid valves of HVAC system) and multiple output signals (compost temperature, air temperature, air relative humidity and carbon dioxide concentration inside the growing room). This paper presents model for prediction for air temperature and air relative humidity inside the mushroom growing room. To determine the dynamic behaviour of the microclimate, the parametric identification method was used. Several models with ARX structures were created. A fit index was chosen to evaluate the quality of models. Finally, optimal prediction horizon for each model was determined.
