3 weeks ago i harvested a dying lowryder that gave me a total of 4 seeds. They look pretty small and I think they are premature but i'm not 100% sure.

I started germinating them 2 days ago and none have broken. I read somewhere about hydrogen peroxide, I also read on here about using sand paper to help break their shell but im not sure if that would damage these seeds.

Any helpful tips to help me germinate these premature seeds?

dude if they dont crack they r prem.

Sanding won't help premature seeds.. H2O2 won't either, pot seeds tend to pop pretty quickly, there is no need to disinfect for long term soaking..
