Hey there 👋
There are so many variables as to why your seeds didn’t sprout. How old they are, where they were stored, the water and method used for germination ect..... I grow a lot of fastbuds genetics, and have had 2/3 seeds not germinate. They do have fantastic customer support, so if you feel you did everything right, I’d reach out to them and let them know
Happy Growing 🌱
