So how far can pollin travel?

I've heard stories of people's plants going to seed because of neighbor's plants. I know it largely depends on wind, but anyone have any idea what a good buffer zone would be?

I recall reading (in a grow book, not the net) that pollen can travel several miles given dry windy conditions.

Yeah that sounds about right.
Pollen is sooo small it's only visible with an electron microscope.

I can go for Miles and Miles! (or kilometers for the standard challenged)

It depends ,if you dont mind the odd seed in there then about 30 yards. The pollen gets caught in other trees ,bushes etc and falls to the ground prior to reaching your plant after approx this distance. But its possible to travel miles if some dust gets caught in a jetstream or wind gusts.

Thanks for the info!
