Last year I used the small wooden coffee sticks in my propagator, the permanent marker writing disappeared & they went mouldy. Very humid in there though.
This year I tried a previously read suggestion of white plastic milk bottles, I thoroughly degreased them, sliced them up & my marker wouldn't write on them. A CD marker did though & although they're less rigid than bought plastic ones, they are working well enough. Worth the effort if you get through hundreds.
