Pot size matter for sexing

So I normally sprout bean in paper cups then transplant to a bigger pot and they exploded and show sex most of the time.

Do you think there is a link to pot size or is it plant size or should I start in the bigger pot ?

Generally easier to sprout seeds in smaller container. Very possible to sprout seeds in final container.

Some people experience watering issues if they start out in a larger container. They're usually a fairly consistent age when you pot up, aren't they?

sometimes it depends on laziness.

but i only sex in the bigger pots when they bush out properly.

I've preflowered them in riot rooters but I usually put the rooter in the bottom of a cup with mix or Perlite so I don't have to pay so much attn to its moisture.
