I’ve just rewatched the video, and one thing I don’t quite understand, why do you grow the lettuces et al. in boxes and not in the soil? Wouldn’t they be better protected against frosts there? Otherwise very interesting to see what one can grow during the cold months.
One thing that always intrigues me is that coriander grows in cold weather, as I originally know it from Southwestern China, or that it is a main ingredient in Thai cooking, where the climate is so much hotter than ours.
