For reasons of legality this is a difficult topic for us to cover but in very general terms the accepted theoretical and anticipated rate of viability of genetically proficient cannabis seeds within a given strain is 75-85%.
That is supported by the following factual article, freely available on the web.
If you were to germinate 10 marijuana seeds you would expect to have a germination rate of around 80% meaning you have 8 viable seeds that will have sprouted and can be planted in the medium of your choice. Whether they survive will depend on the viability of the seeds and how well nurtured they are.
We do stress that GYO Seedbank in no way condones or promotes the germination of cannabis seeds outside of a country or territory where it is legal to be able to do so.
