Had the same problem with my Afghan pearl seeds, 1/4 made it to veg whereas everything else germinates no problem. I was 1/1 on the AP CBD last year and it was amazing so idk what happened with Sensi seeds
@Humble_Lion, 0/10 is crazy, the seeds must have not been viable. I think there are a lot of trash seed banks . As for Sensi, the Afghan pearl seems like an anomaly overall, but definitely still a problem with that batch of seeds.
@musashi_miyamoto, interesting to hear similar things from your end, might be worth to open a question on this topic. i had the same this year with the cbdivine/paradise seeds strain(photo) i tried to grow, not a single out of 10 made it.
