They've actually been curing in mason jars for the last week and a half. Their original smell has returned even stronger. The hay smell is completely gone. Thanks again for everyone's help.
This is my first grow and my plants are currently on their second day of drying upside down on hangers. They are drying in my grow tent with an avg temp of 65 and humidity at 55. They were grown in coco coir and perlite. My question is about the smell. They smell like hay or grass right now...
