pumpkins in root cellar? There were some tricks but can't find them?

I have no space in my 200 foot house for storing pumpkins, unless I welcome them to my bed.
I know a root cellar is too humid for them. But I remember somebody had ideas how to do it. Spray with vinegar? Cover with oil?
Please, does anybody know?

I think the more important issue is temperature, unless it's so humid as to encourage condensation and mold.  Winter squash and pumpkins need to be above 55F/12C to store well long-term.  What I did is simply raise my bed in the house tall enough to create extra storage underneath, and put all my pumpkins and sweet potatoes (which also must be stored warm-ish) under there.

I sprayed the pumpkins with vinegar and no mold!
But they are having cancer. The skin is disappearing from areas that are in contact with the shelves. Really puzzling. The skin just.. disappears???

Have you cured your pumpkins to allow the skin to dry?

To cure the pumpkins place them somewhere sunny and sheltered for 1-2 weeks.

I have also read to store them upside down because pumpkins will continue to ripen after they are picked. This process is said to make the pumpkin taste even sweeter. Though folks need to be careful not to damage the stalk.

It might also help to store them on cardboard or maybe straw.

Those pumpkins are looking really tasty.

Anne thanks ❤️❤️❤️
I did leave them outside for a while but clearly that was not enough. Maybe I'll share the bedroom with my harvest for a while!
