> it stays fresh for about two weeks
That's hardly special. I've stored lettuce that I bought commercially for 4 weeks and it was fine. So that's 4 weeks plus however long it took to get to me. (I bought too much by mistake.)

It also gives head lettuce at best two weeks at five degrees centigrade. So, two weeks at 10 degrees seems a good result.
On the other hand, the article says _about_ two weeks; they might mean 'ten days plus', and 'freshness' may be highly subjective (I bet there is a standard for measuring lettuce freshness)
Frankly, if you're not using a head of lettuce in 2 weeks something is wrong with your eating and/or buying decision making :-)
