What's on your lettuce?

[Monica]

To get the same solid film in the video it has to be a very frost resistant romaine lettuce. Normal lettuce would die at the temperatures required for this.

I looked into it again after I went to clear out a high tunnel I had rejected the past couple months...it had gotten too cold for even the tunnel to protect the lettuce, and while it hadn't died, it wasn't marketable quality. As I picked the lettuce out for the goats, I noticed all of romaine had "blisters" and I was able to peel the skin off just like the video. It happens with other types of lettuce too but I think the romaine skin is easy to peel.

Nice to have a conspiracy theory refuted. Too bad it doesn't happen more often.
