Just an idea…
If we ever get pallets we usually use them to make the sides of compost heaps, but this idea from Eddie has potential, he saw it on FaceBook.
I googled “pallet vegetable growing” and got half a million interesting ideas!
I suspect that the slugs and snails would like this one, as they can hide out of sight very conveniently.
One idea I saw suggested planting the pallet horizontally and setting it on edge as a living wall once the plants were established, but this would probably not do for the brassicas in Eddie’s picture.
