Obtaining pits is simple. Just eat a few cherries and save the pits. Make sure you wash the pits very well and not leave any fruit residue. The sugars can cause molding and fungus.
Using our 12 compartment seed trays, using potting soil, 6 compartments have pits, the other 6 compartments contain cherry seeds. We cracked several pits open with hammers to obtain the seed. Unlike previous seeds, they are not inside a greenhouse. Doing some research online, I have found that the greenhouse is too hot for the cherry and may harm it.

In The Refrigerator
One method I have been reading online is to get a jar or bag and fill it with moist soil and seeds. Keep the soil moist and leave it in the refrigerator for up to 90 days. During those 90 days check to see if any sprouting has occurred.
Trevor and I are using jars. One jar will have 20 pits, the other jar will have 20 seeds. We will see which one grows faster.
