Night Time Extra Coverage
To help keep as much heat trapped inside the structure as possible and two old boat tarps are used to cover the cold frame to help act as a thermal barrier. Blankets will also be put on first and then the tarp to really help minimize the potential heat loss.
These are removed in the morning to allow natural sun to be exposed to the plant when the artificial light is off and cooling becomes a greater concern.
While there are different greenhouse covering material to consider with the light transmission and U-values, the simple boat tarp is easily available and does the job that is needed. However, the link below shows some of the details on the different options available.
