Why should you put bubble wrap in a greenhouse?

Gardeners add bubble wrap to their greenhouses primarily to add another layer of insulation. Bubble wrap retains any valuable heat from the day, which can be used to protect against frost at night.

 

It is important to remember, however, that bubble wrap retains heat. So, during the warmer months, it is critical to monitor the conditions inside your greenhouse to avoid any plants wilting.
