Talking about letting them do what comes natural...

..I'm a great believer.. Except when it comes to pollenation.
Naturally I'd say a male has a 10-12 day pollen Window.
If you let them do that you really screw up your seed collection..your available seed will have a 10-12 day difference in maturity...that is no good what so ever..

..
Make a pollenation Rule...no more than 24-48 hour exposure to males.
That way All of your seed harvest will be ripe in a 24-48 hour window..
Simple things make a big difference...
