A Good Way to Avoid Rain of Arched Greenhouse
The pepper growth is just during the rainy season. If the rain get into the tent, it will cause the multiple diseases for pepper and damage pepper growth. In some serious conditons, there are many dead pepper trees. If the rainy days last long, the greenhouse temperature will be high, and humidity in the greenhouse also will get higher. When the rainy days pass, the pepper will not come to normal grow imediately.There is one good way to avoid this damage. It is to dig a ditch under the air outlet. When it comes to the rainy days, the air outlet can keep open. In this way, it can avoid bad ventilation problem in rainy days, decreasing the inner temperature, and it can reduces the humidity in the greenhouse. It serves multiple purposes.
But this type of ditch is good for slight rain, and the time of the duration of rainfall is short. When it rains quite a lot, the air outlet should be closed and pull down the side film to prevent rainfall getting into the greenhouse.
