I do believe your theory is correct. I recently did some rudbeckia seeds & unfortunately only 1 came up & I did make sure there were no crevices but what are crevices to our eyes in relation to crevices to itsy, bitsy, teeny weeny seeds?
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others. ~~ Sharon Brown
