Breeding - how far can a male's pollen travel

I want to breed one or two females, my question is how far away should I keep my other females to keep them from getting any pollen?

well pollen can travel through the air or on insects , im no expert on this but i always move my hermies into a seperate flower room , needless to say i had to do this in another property, it also depends on if your grow rooms are sealed or not , obvious i know , just trying to help , i will be interested to see if anyone has more input ....

if your breeding outside i would say a good ways. i would scout another area miles away to do a breeding project. like bloomfeild said, insects can spread pollen and could also become airbourne. i would play it safe.

Ok thanks, never even thought about insects

The further the better in any case. Insects should not be a major issue unless planted too close. Keep your males down-wind, and keep the males topped and trimmed.

The less vegetation you have on the male plant, will ultimately reduce the amount of pollen floating in the air. I kept 3 males .5mile down-wind from females this year and did not have a problem.. the main reason for this is when it came time for the males to flower, there were only a few good shoots on each plant.. taking poleen production to a bare minimum.

A top is all you need to make seeds.. a top to a male that is.

.

pollen can travel for miles. ofcourse a male cant produce a concentrated amount of seeds on a female miles away, but it can produce seldom seeds here and there. wherever those pollen grains touch the pistil. for breeding, i would choose a completely seperate spot (different forest or w,e entirely). just leave males and females together. or if you want to do controlled breeding, just take in a few of your best males indoors, then bring the pollen to your grow area. kill all other males.

Yes make sure you kill all the males that you are not going to need.

Theoretically,miles. Practically, around 100 yards from my experience. I've always grown in creek/river bottoms and on hillsides in the humid low wind regions of central and southern Appalachia. Things may vary in a less humid place w/ higher winds.
