First fail in a long time Fast Buds

piggysperpetualGrow 18 hrs soak, didn't sink. 24 hrs in dark warmth, didn't pop. Going to wait another 24. Update: Failed. That why you dont hoard seeds. Happens sometimes. Make sure to use them within their warranty. Fast Buds germination warranty is three months. No big deal. Just make sure to document your germination method and conditions when germinating. Update: I let this germinate for a week after, no results. After receiving my replacement seed I popped the dead seed open. Everything was healthy and normal. I think maybe doing a drop of hydrogen peroxide could have weakened this shell enough to let it sprout.
