Germinating with Greenpoint for over a year now in paper towel in puffed up ziplock and toss them on top of my tent for some warmth. I believe I have had three not germ. That is well over 9/10 and most packs have 11-13 seeds. Greenpoint stock has also been the fastest overall and most get put in soil mix at 36 hours and by 48 hours the root is growing through the towel. Just the method I have used for a long while. If anything, I have more males with a few Greenpoint strains than SOME seeds. More exceptional buds also!
Smaller, light colored seeds usually mean you have smaller, light colored seeds. I have grown c99 and older hazes that had tiny grey seeds that always popped and made great herb. It does seem that Indica plants make bigger seeds.
