I know lowland seeds don't last long, how long do highlands stay viable?
10 minutes less than you have them lol
MICKEYS GROW LIST
Adding to the good info given already,
I would think that the length of time has a lot to do with the conditions they are
harvested & stored under.
Not that this helps....
Experience is the best teacher. At least it used to be.
But then, common sense isn't so common anymore, is it.
I've heard that they germinate best in lowland temps... Not just the lowlanders, but the highlanders. Maybe higher temperatures active enzymes that speed up the process?
