    hmm… I wonder if an early season coldframe could double as a solar oven in the peak summer months..

      Love the way you are trying to stack functions Sophie 🙂 I haven’t tried but maybe? Solar ovens use insulation and black surfaces to achieve the temps they do whereas cold frames do not have those characteristics. Throw a thermometer in one this summer and give it a try!

    in the tropics, I won’t be needing green houses but shade houses to keep off the heat – do you have info on these sorts of structures? I know many just don’t bother to grow lettuce or spinach cos they will just seed but I want to try cos I like to eat them 🙂

      Bill Mollision’s Permaculture Designers Manual has some sketches but you can also google “high tunnel shade cloth” to see how people are using high tunnels for shade.
