Place newly harvested pumpkins on carpet scraps in a single layer to protect against bruises.
Check the curing facility with a thermometer and hydrometer for a temperature between 80 and 85 degrees Fahrenheit and humidity between 80 and 85 percent. Use a space heater to maintain this temperature, if needed.
Cure the pumpkins in these conditions for 10 days.
Transfer the cured pumpkins to a cooler, dryer storage facility where the temperature is between 50 and 55 degrees and the humidity is between 50 and 75 percent.
Store pumpkins for up to three months before use.
