With the temperature dropping, we all know the winter is coming. And our beloved flowers and vegetables are confronted with the cold weather. Don't worry. Here is some tips for you.

Meanwhile note the cracks around to minimize the heat dissipation. We can add double sun-shade net in the north of the greenhouse to form a windbreak and reduce frost damage.
