thank you so much for posting that link (recognizing sex of a seed). I am thrilled to see something that might help with early detection of female plants. I have never heard of this, but am going to go through my seeds and start sorting and testing it out. How do these websites, etc., guarantee female seeds that they are selling?? They have to have a method, maybe this is it! What was the results from 2010's growing season, were the seeds you thought were female truly female plants?
