So put them in water for 12 hours and they both sunk to the bottom. Left them for 2 more hours at the bottom. Then put in wet paper towel. They both crack after 2 days. Both of them grew their tap roots to 2cm in 3 days. Both were moved to Rockwell after that and both are now coming up and the shells are opening. So far very happy with the growth. Thanks fast buds.
