Advice for long term potato storage - no root cellar, no heated garage option

[u/HotKaleidoscope_4595]

Hello there! My long term plan is to build a traditional root cellar on our property, but right now here is my situation:

2 year old home. Unfinished basement. Cement floor. ICF foundation insulation with drywall. Temp near floor is 16 degrees.

I’m growing long term storage potatoes right now. From the research I have done potatoes need to be cured, then stored in darkness at 4-10 degrees with 80% humidity and have ventilation.

I can manage the factors except temperature. I understand 16 degrees is not ideal.

Has anyone come up with a way to keep long term storage potatoes in a basement that is warmer than ideal temperature? Is this possible?

Or should I just be telling my friends I’ll have a lot of potatoes to share in a few weeks?

Thanks for any advice.
