Hey, does anyone know the step by step process of cold stratification when it comes to seeds?

You are removing the ABA or abscisic acid by cooling the seed. About four weeks at 4°C or 40° F is required to activate the enzyme that degrades all the abscisic acid in the embryo and allowing growth. This is intended to hold the seed til spring so it also called vernalization..
Place the seeds in barely moist starting media like sand or vermiculite in a small baggie & seal. Alternately place them between damp paper towels so they are just visible with only one paper layer on top. Place in the fridge. After 4-6 weeks take them out into a warm room in a lighted area and watch for the appearance of the radicle, the embryonic root tip to split the seed coat. They are germinated and ready to be planted. Handle with clean hands.
High moisture levels in the sealed containers can allow fungus growth causing them to rot. Fungicide sprinkled on the seeds may help but it may also slow some seeds from germinating.
