Just got my order in from Tude. In two of the seed strains 3 or 4 of the seeds are big and healthy and the rest look like little runts about half the size. Does seed size affect germination rate?
seed size doesnt say anything good or bad about what the plant will be like. smaller seeds should be planted slightly closer to the surface of your soil so they can break ground.
sativa seeds seem to be smaller indica seeds larger. like others have said, the color (striping) is a good sign of good seeds. possibly if they were crossed sativa and indica the smaller seeds are more sativa? that would be my guess. they should germ just fine though
