Seed size comparison

Here's an interesting pic that shows the 2 different seed sizes. That the same male will produce on different females.

I'm not expert, but I had the same results once. I pollinated a Cheese plant with Mulanje Gold male a while back. I did two brushings...at 3 weeks flowering and again at 5 weeks. When I chopped I noticed the seeds that were two weeks older were twice the size as the younger ones. Not saying that is what you did, but that was the only time I ever had seeds that were different sizes.

theres tons of diff sizes and shapes, genetics my dude

in general saticva mothers produce smaller seeds. the smallest seeds i've had have been from mekong haze, mixed sativa & haze x skunk, while the largest were from a straight up afghani looking jack. the mother determines seeds size and shape. the buns gotta fit her ovens. i forget what strain it was, but something else i grew had really oblong seeds too like skinny potatos.
