A cold frame greenhouse should be an essential feature of every home garden. It will provide shelter and warmth for plants and enable them to thrive outside of their normal period of growth. By extending the growing season it is possible to harvest not only superior quantities of fruit and vegetables but also better-quality produce, as it will have less exposure to the weather and bugs. The warm protected environment also enables a more extensive variety of crops to be raised.

Traditionally a cold frame was an unheated box or other structure with a transparent cover, usually made of glass, that could be lifted up or slid open for ventilation. Now, there are a variety of designs, made of different materials but they all function in the same way. The clear panels or covering absorbs the rays from the sun, which heats up the interior of the unit and this heat can be regulated by some form of venting.

There are number of factors that need consideration when selecting a cold frame greenhouse. These can include:

  • Available space – Do you have a large plot or just a small yard?
  • Location – Will it be in a sheltered or open location?
  • Construction – Do you prefer a wood or metal frame or collapsible?
  • Cost – Depends on size and materials

Taking all these factors into account, I have chosen a representative selection of those available. Continue reading to find out more.
