Empty Mammoth Sunflower Seeds

Asked June 5, 2019, 3:16 PM EDT

Why do most of my sunflower seeds not have a seed in the middle? We originally grew them for a project in February (harvested them June 3rd) , and we kept growing them out. We recently cut the heads off and harvested the seeds, then we followed an online recipe on how to cook them. After cooking them we found that most off them don't have seeds. We haven't eaten many but most of the ones we have eaten had no seeds. We are wondering if we need to let them grow longer.
