The plant factory was a rapid-developed agricultural technology in East Asia in the past decade. It provides a well-controlled environment for crop growth to guarantee better yield or quality. However, its high energy consumption always leads to criticism. A good environmental control strategies would achieve better plant growth environment or efficient energy utilization. Unfortunately, the control strategy was usually based on the previous growth experience in the field. It is necessary to develop a fast and low-cost, easy-replicated approach to verify the performance of the control strategies. The objective of this study was to develop a microclimate model to simulate the environment conditions when using different environmental control strategies. This model was based on temperature-humidity equilibrium and plant evapotranspiration equations. The ambient environmental conditions, parameters of control strategy, plant evapotranspiration rate were input into this model and the outputs were the calculated temperature and humidity. A desktop grow chamber was used to verify the feasibility of the microclimate model. Ten plants of hydroponically grown lettuce were grown in this chamber. The results shows that the simulation results of this model fit the real cultivation results. This model provided an easy and low cost way to screen the feasible control strategies by simulated the environment change in a plant factory.
