The greenhouse insulation performance in the winter is relatively poor, the temperature will drop to very low, making the temperature difference between day and night is quite large, in order to solve this problem, we must cover the straw when the temperature is low. This is a reference greenhouse planting practice, relying on the sun during the day to warm up, at night, cover the plastic sheeting with straw, greatly increasing the insulation performance.

So how can we keep the plastic greenhouse from getting wet? To solve this problem, the following method can solve this problem:

Ventilation hole: Leave a hole for ventilation in the greenhouse. This hole should be left on the roof. Leave a gap of about ten centimeters between the roof and the scaffold. During the day, the grass curtain can be rolled up for ventilation until the evening. It can still be ventilated when it is put down, but since the top is still covered with straw curtains, the plastic greenhouse insulation performance is still very good. If you encounter windy weather, you can also put a part of the straw down during the day to cover the vents.
