Cold-grown: Tiny lettuce leaves, crisp, fresh and delicious…and grown oh so slowly, without cover, in the unheated greenhouse, through many freezing nights, some down to -15C. Still a while till it’s big enough to harvest, and it was seeded way back at the beginning of October: that’s already 50 days compared to the usual spring/summer 25-35 days for baby lettuce mix). Also, the cold effect gets trickier as the leaves get bigger. All in all, though, seeing food grow in the cold with a minimum of help is quite fantastic.
