Conversely, Male seedlings are green stalk. No red in the petioles, they also are green. They grow faster, taller, leaner and using those criteria, I have not been wrong yet.
I am pretty sure that I have results from my experiment using this theory.
Out of 4 plants, I am pleased to report 3 successful identifications at day 6 with a good argument that we actually identified the 4th one also and were 100% accurate !

Please reference this post: http://boards.cannabis.com/grow-log/...ml#post2167903, post #8

As predicted, #1 is a male, #2 is female, #3 is male and #4 seems to have possibly hermied on us due to stress... if it was actually going to be female this Early ID was 100% accurate just based on color at day 6!

Even at 75% accuracy, this is exciting... I can't wait to try this again!
