Outdoor Seed Production and Germination

I'm curious about the life cycle of outdoor marijuana in areas that experience cold winter temps and precip. If a female plant becomes fertilized, it will begin to produce seeds. Sometime in the fall those seeds will be mature and will begin to fall off or be eaten by birds. In the wild these mature seeds fall to the ground or are redistributed in the waste of animals.
My question is what prevents these seeds from sprouting in the fall and then dying because of cold. How does the marijuana plant ensure that its seeds will remain un-sprouted until the following spring? It seems to me that if a plant drops seeds in sept or oct, the conditions would be optimal for those seeds to start sprouting then and then die when the temp drops in a month or two, never being able to mature and produce more seeds.

seeds wont germinate well for the first month or two while they are fresh, they need to dry out a bit first, and usually require warm moist conditions for several weeks before they do germinate, fall is not usually condusive to this, being characteristicly cold and dry, however it does occationally happen, also some seeds wont germinate the first year and will wait till the second spring, no doubt a defence for the futer populations in preparedness for a disaster like this year, all the wild hemp has pretty much died off and there will be no new seeds. the futer of the species in this area depends on the second year germinating seeds to hatch. I would say the varying moisture levels, freezing over the winter, and cold nights in spring effect the germination rate.

when you germinate seeds, they have been thourally dried, i think that is the main reason they all germinate usually and when left outdoors over the winter some just don't. also they germinate in perfect conditions, perfectly dried to perfectly moist, never drying out partially and always comfortably warm.

This is all theorys of mine so im not guaranteeing that it is true, but thats at least part of what is going on with germination in nature.

Thanks for the quick response beaner. Looking forward to the newest update on your grow.
