How to prepare a greenhouse for winter cloudy and snowy days

Encountering snow and cloudy days is the most annoying thing in winter greenhouse cultivation: insufficient sunlight, low temperature, and so on. Fortunately, a combination of insulation and lighting systems can ensure a stable production under daylight temperature in winter. 

Build thermally insulated walls in the sunlight greenhouse
Sunlight greenhouse is just a general term for vegetable greenhouses, and there is still a very big difference in the actual construction of sunlight greenhouses. The most common walls used in greenhouses come in two forms: earthen walls and brick walls, both of which are helpful for cultivation in winter.

Use insulated cover material for sunlight greenhouses
The cover material of sunlight greenhouses includes insulation quilt and plastic film. The quilt is the core part of the insulation system in winter, bearing 50% of the thermal insulation effect. When selecting the thermal insulation quilt, it should be waterproof and windproof. 

How to solve the problem of insufficient light in the greenhouse?
When there are several cloudy or snowy days in a row, the sunlight is certainly far from sufficient to allow the crops to carry out proper photosynthesis, which would directly affect the quality of vegetables. One solution is to use artificial lightings, such as HPS or LEDs.
