G'day all, I'm from down under, Australia - the southern hemisphere and in a temperate climate. I'm interested in determining how to create a specific set of conditions for an artificial winter during our summer period to grow leafy vegetables and other types of produce winter loving edible plants. I've never heard or come across something like this before, but I consider it possible to grow winters plants out of season, as we can grow summer and spring crops out of season! I'd imagine the light levels, atmospheric and soil moisture would all need to mimic winter conditions. Is there anything else I'm missing? Cheers Eco EDIT: The conditions would need to be useful in a controlled environment - I guess the opposite to a hothouse, but I know only of a shade house and any structure would need to keep the summer heat out (which can get upto 48 degrees celcius).
