How do you store your seed long term? In the refrigerator or in a moisture controlled area? I am not up on vegi seeds as much as i am up on tree seeds, but I know if you get them too dry for too long, they start to decrease in germination percentages pretty fast. The farmer next to me left his seed outside in the back of his truck on accident on a 90 degree day. Not a single seed came up for him this year. Was it because the glass hot them too hot or to dry, I do not know. Tree seeds like to stay moist or they loose a lot of their potential.
Why not keep your normal jack o lantern seeds? They are free and most times grow better than the purchased ones.
I simply keep leftover pumpkin seed in the plastic bag they came in inside a cardboard box on a shelf in the unheated section of my shop. Temperatures will vary between 40 and 70 degrees depending on time of year. I even plated two lbs of last summer's sweet corn seed and it germinated in less than a week.
I never had much luck keeping seed harvested from my pumpkins. The seed would germinate well but not produce a good crop.
