Know this is an older thread, but had to bring this up. In the 70's, there was a theory that pollen from pre-flower to pistols of pre-flower produced seeds that would make plants earlier than the parents. While I never believed this, I've never heard any thing to either prove or dis-prove this theory. Since the pre flowers would still have the same genetic make up, I don't see how it would make a difference. Any other opinions?
