A certain amount of air flow in the garden greenhouse can reduce the occurrence of plant diseases and prevent the leaf area from being watered for too long and becoming sick and moldy. For human health, proper air flow can make people feel cool, increase the air exchange between indoor and outdoor, and improve the freshness of indoor air. If the greenhouse is too closed, the concentration of carbon dioxide produced by the respiration of plants and people will gradually increase, which is not good for human health.
In late spring and early autumn, due to the strong solar radiation and greenhouse effect, the temperature in the garden greenhouse during the day is often above 40 °C, which is far higher than the suitable temperature for crop growth, which greatly limits the growth of perennial flowers, seedlings and long-season crops. Cultivation. In order to maintain a suitable ambient temperature in the greenhouse facility, it is often necessary to adjust and control the temperature conditions of the greenhouse facility through ventilation, or even setting a wet curtain fan cooling system.
