PURPOSE:To automatically control temperature in a greenhouse for plant culture by detecting rainfall and increasing ventilation when rainfall is reduced by a ventilation mechanism and conversely decreasing ventilation when rainfall is increased. CONSTITUTION:In a greenhouse 1 for plant culture having a ventilation mechanism, when rainfall is reduced, the ventilation is increased using the ventilation mechanism by a detector 13 for detecting rainfall and conversely when rainfall is increased, the ventilation mechanism is controlled so as to decrease the ventilation. Thereby control of the interior atmosphere in the greenhouse is carried out. |
