Various Cold Frame Designs

I built three different types of cold frames from old windows and recycled scrap wood from other construction projects. They are currently being tested to see to what extent they influence the yield as well as which one is the best out of the three. Results such as daytime and nighttime temperatures, humidity will be posted here soon. All three are about 5-10 cm dug into the ground. The three cold frames are the following:

  1. Deep cold frame (49 cm wide /110 cm long, 42 cm tall)
  2. Shallow cold frame (50 cm wide/ 120 cm long, 26 cm tall)
  3. A-frame type cold frame with vent doors (own design)
