I’m a first time grower and after my first harvest the rest seeds wont germinate, I’ve done the float tech method as i did with the first set that grew but no germination , I’ve also tried the paper towel method and direct to dirt but still didn’t get results, i got all seeds from same website.
my first grow was 5 seeds, I’ve tried germinating 12 seeds (different strains) with no result , what could i be doing wrong ,or the seeds are all duds???
