Ive had whitish color seeds that germed, and others that didnt germ, the white ones always take longer though if they are gonna germinate in the paper towel method...
Okay and good to know but I meant the OP. He says he got them from a seed bank....what strain? Some strains have white seeds and I have a hard time believing they sent him immature seeds. That's just doesn't make business sense on their end...short term thinking rarely works out.
