Hello Chris and well done on your boxes.
I am interested to see how they grow because you have colder weather than us: my boxes have not been tested below 14F (in the greenhouse) which was in December 2010.
Over they ears I find the most hardy lettuce is always Grenoble Red, and others less so. Again that will be interesting to see!
Incidentally your compost looks excellent but probably has fewer nutrients than purchased composts for potting, which I use.
For anyone curious to see the video it’s here.
