did you scuff them with an emery board? did you keep them in the fridge for awhile before popping them ? from my past experiences nirvana's gear usually pops with ease.
No emery board and no fridge... same technique as always. No matter the seedco, for fems i generally pop 1 or 2, they usually root out no problem. All 5 failed, never happened to me before, and i’ve grown plenty.
I didn’t mind the duds as much as the cross-examination followed by such a measley discount on another purchase. Too bad, but there are more seedcos out there than i’ll ever get to.
Their loss...
