I wonder if anyone has bought and put together the cold frame that Lidl is currently selling (in Ireland at least)?
The 2 lids on my frame are not large enough, as far as I can see. The space is 24in deep, while each lid is 23.5in deep; so the lids fall through the space.
There are some rubber seals provided with the frame, which do not seem to be mentioned in the installation instructions, but I do not see how these could cure the problem.
