Greenhouse Cold Frames: The simplest form of Greenhouse.
Greenhouse cold frames are by far the simplest form of greenhouse, and although the concept and their construction is fairly simple they are a great addition to both the novice and professional gardeners.
They use no artificial heat, so use and startup is pretty easy. A frame solely relies on the solar heat that it traps through the cover or greenhouse glazing materials.
Again just like any other greenhouse the same principals apply. On warm days it may be necessary to vent or even shade your greenhouses.

They come in many differnt sizes. As we mentioned they are appropriate for both the novice and professional alike. There are designs small enoughto be used on an apartmentporch or back patio.
