Have upgraded it with a second, thicker foil and so far life in it seems to continue. Tomatoes, pumpkins and zucchini and basil are still alive! And soon it will get warmer.
Only the cucumbers are dying 🙂 at the end of the foil that was not long enough to cover all.
interesting experiment. obviously colder is even better than in the house a 22 Degrees Celsius!
So there we have it: “only the tough ones will end up in the garden!” 🙂
