Many miles if the wind is right and there are no obstacles.
not to be an arse-hole , but do you have any research papers that talk about hemp pollen drift?

Probably profit, by the size of this operation?That's a good question.
I'd guess on that size hemp production fem seeds would be costly and if it didn't diminish the finished hemp product regular seeds would be used to increase profit.
The size of this particular field frightens me a bit, as I’m doing a small crossing/breeding project of my own right now. Maybe I should take it indoors to tackle these unwanted guests..I would think It depends on the prevailing winds. In my opinion the worst thing that might happen is you will get lightly seeded weed , no big deal. I regularly move male plants just 50’ or so to collect pollen and I end up with very few if any unwanted seeds .I realize that my few male plants don't compare square miles of plants but they are much closer. I think you should just try a few and see and then we'll know. You could try growing varieties that flower at different times than the hemp , or you could use a row cover to keep the wind - pollen off them .don't give up !

Reasonable question.
I read an article a few years back about pollen drift going 30 miles from Morocco to Spain across the mediterranean sea. I imagine with an updraft and no obstacles, pollen could go miles.
I did a quick search and there seem to be lots of articles about hemp pollen drift. I'll need some time to read a couple before I can reach a conclusion though. Hopefully later this evening...gotta go feed the chickens now.
I think CBD flower is just tiny part of overall hemp production. Seed (oil) has to be much more common. Can't make seed without pollen. Often they use hermie strains, they consider it a benefit because all plants make seed, but often also not and just regular male/female is used.
Absolutely if you are breeding. I do suggest you check out when the hemp males start flowering this could be keyThe size of this particular field frightens me a bit, as I’m doing a small crossing/breeding project of my own right now. Maybe I should take it indoors to tackle these unwanted guests..
Viability is moisture based, they've found 240M yr old pollen grain fossils....it's the inside that matters. Whichthanks for the reply
i was hoping there were a few Horticulture majors at the Rag who knew for sure
otherwise , it has been awhile since studying the topic of pollen drift , but last I recall there were a lot of opinions , from a few hundred feet to a few hundred miles
seems to me viability would be a good place to start…people go to great lengths to collect and store pollen and great care is taken so the pollen won’t go bad…
Most hemp strains are not auto. The only one that is that I can think of is Finola. Some of them are just very early despite not being auto.I came by a hemp field yesterday (Germany). There were males and females. I didn’t see hermies, but I didn’t look out for them. They were already flowering, which I found strangely early. So maybe for seed production they breed auto traits into the hemp strain. Or is hemp always auto?

That’s really early indeedI came by a hemp field yesterday (Germany). There were males and females. I didn’t see hermies, but I didn’t look out for them.

Yes I imagine autos would be very productive for seed production .they are small and fast and not wasting energy on producing stalks, requiring less fertilizer. If @Mahalo85 is lucky the farmers by him are growing aut

If there are makes sure can if only fems and no hermies you may be ok. I know pollen can travel up to 5 mikes in strong winds.Fellow growers, as I did a small hike with the missus after dinner last week I’ve stumbled upon a ten by ten square miles hempfield about 3 miles from our home. This is a commercial hemp field from Hempflax [Sensi seeds], and I was wondering if the pollen from these fields could screw up my little [10 plants] yearly backyard growing operation? Any recommendations, tips, tricks or should I just give up straight away..
Yes lightly seeded weed is just fine. My sour vengeance threw a nanner cause it has seeds but not a ton. Just a few and the weed is great. My best stuff yet. I roll like a half ounce at a time so I can send some to my son. He is very busy so I like to have it ready for him. I send it in the tubes to keep it fresh. He work like 12 hours a day 6 days a week.I would think It depends on the prevailing winds. In my opinion the worst thing that might happen is you will get lightly seeded weed , no big deal. I regularly move male plants just 50’ or so to collect pollen and I end up with very few if any unwanted seeds .I realize that my few male plants don't compare square miles of plants but they are much closer. I think you should just try a few and see and then we'll know. You could try growing varieties that flower at different times than the hemp , or you could use a row cover to keep the wind - pollen off them .don't give up !
Greenhouse will not keep out the pollen unless it is completely sealed.
@bigsur51 should give you some idea maybe?
My worst nightmare is a hemp farm within 20 miles of me.
