The day after I post two week pics, I get my first sign of gender. This is unbelievable... The seedling is two weeks old, 1 1/4 inch tall, and has pollen sacks. They're only visible under high magnification but, they are definitely pollen sacks.

It's not a big deal. I want a male and expect to get more. But, I'm absolutely stunned to see definite sex determination at this stage.
