In a glass bowl, add the sunflower seeds, water and sea salt. Make sure that the seeds are all under the water. Stir and set aside for 7-12 hours.
Rinse well with cool water.
Preheat the oven to the lowest setting, usually 170 degrees. Line a baking sheet with unbleached parchment paper.
Pour the seeds evenly over the parchment paper. Roast on low heat for 8-10 hours until the seeds are dehydrated.
NOTE: If you have a dehydrator, this process will be easier but may take up to 12 hours to dehydrate the seeds.
