Not even kind of true. From all the tons of research I've done the the studies say standard distance on the wind is around 100 yrs. However the insects that are pollinating can travel miles. For instance a bee can travel around 3miles on average.

I don't worry about pollen traveling very far, since it usually gets blown into surrounding noncannabis vegetation, especially for those who grow in areas with forests or other physical obstructions that catch and hold the pollen, etc.

However if it's near an open area, like a body of water and wind driven, it can travel for miles. That's what the excerpts below from a study in Spain conducted in the 1990s indicate anyway.

ATMOSPHERIC TRANSPORTATION OF MARIHUANA POLLEN FROM NORTH AFRICA TO THE SOUTHWEST OF EUROPE
BALTASAR CABEZUDO,*'~ MARTA RECIO,* JOSt~ MARIA SANCHEZ-LAULHI~,~ MARIA DEL MAR TRIGO,* FRANCISCO JAVIER TORO* and FAUSTO POLVORINOS~


Abstract---As a result of aerobiological samples taken on the Costa del Sol (S. Spain), Cannabis sativa L. (marihuana) pollen was detected from May to September 1991-1996, always sporadically and usually during the afternoons. Sampling was by two volumetric spore traps set up in Malaga and Estepona, two coastal towns approximately 90 km apart. A study of the days when this pollen was recorded points to the movement of air masses from North Africa to southern Spain. Furthermore, the isentropic air trajectories calculated for these days reinforce the possibility of the pollen originating in marihuana plantations in northern Morocco (Rif). This study demonstrates the application of aerobiology to the control of the source, quantity and phenology of the crop. © 1997 Elsevier Science Ltd




CONCLUSIONS
It seems probable that the Cannabis pollen which reaches southern Spain has its origin in plantations in northern Morocco. Based on the quantities of pollen detected, the annual Cannabis sativa harvest can be estimated and increased trafficking foreseen between the producing region (Morocco) and the consumer countries (Europe). Independent of the quantity, recent years have seen an increase in the length of the period during which marihuana pollen is recorded (number of days be- tween the first and the last grain registered), which seems to suggest an extension in altitude of its cultiva- tion because the north of Morocco is very mountain- ous. This would harm the native Cedrus woods, and there is also the possibility of producing allergenic reactions in some sensitive individuals.

Oh I know...I've read that before. I've also read that pollen can travel 2000 miles given perfect conditions.
I guess if you live in open plains and such you would have to worry...however I don't see where most people live with trees and houses...forests..mountains etc etc that they are going to get their crops pollinated from 6 to 12 miles away. Shit if that were the case .... every noob growing bag seed males would have pollinated every grow I've ever had.
Tons of people grow around here and most are too dumb to know a Male from female plant until it's too late.
Idk... I guess it sucks if you live next to a hemp farm.

It does... But what can ya do. They just started two new fields near me this year. At least only one of my plants got pollinated really bad this year (never seen so many seeds). The other three did end up with a few but not bad. At least there's still indoor. And my lady has ok'da small greenhouse for next year.

Hopefully a greenhouse will limit my outdoor exposure to stray hemp pollen. Because you know the big farmers don't care about the rest of us. And they are not going to change their practices just because they are harmful to other people's plants. Errrrrgggg.

Agreed, the study represents an extreme and most normal growers don't have to worry about foreign pollination if there aren't males close by. At least until hemp farms start being commonplace.

Being a sneaky forest and swamp critter I never worried much about random pollination unless I inadvertently misidentified a young plant and planted a male. Even then, regular tending and most could be pulled before they got frisky. Using fem seeds can reduce that problem.

Although, I had a volunteer sprout up last year that had seeded itself, it was a girl. Grew to a decent size all on it's own, undetected by me until it was already flowering on the back of a dirt pile I was recycling, from a seed that must have dropped into the dirt from an intentional single branch pollination I'd done the year before.

This year, I've found one volunteer, a little 18" female. So it's possible there could also be self induced males in a grow spot or dirt pile people are unaware of. Nature finds a way. :eyesmoke:

Yeah I never understood why the governments war on drugs outlawed the easiest way to rid cannabis farmers.....duh you fucktards now pot smokers in KY were thinking hemp legalization was awesome. Maybe they'll think differently when sensi goes up about $10 a gram...thanks hemp farmers....umm kidding. Outlaw hemp 2020 or educate the farmers growing it at least

If you see these fly’s don’t spray them or swat them! They areBee-like Tachinid Fly larvae are lethal predators to insects people may find problematic. Most of these fly larvae feed on the caterpillars of pesky moth species. Because of their diet, some Tachinid Flies have been deliberately imported from other areas to control destructive moth populations. The female Bee-like Tachinid Fly lays a couple of fertilized eggs on or near a moth caterpillar. The caterpillar may inadvertently eat the eggs as it chews on the leaf the eggs were on. A larva will feed on its internal parts until the caterpillar dies. The fly larva will then drop to the ground and dig a burrow where it will pupate and develop into a flying adult.4B3640D2-E8F4-484D-83D0-C8D93AA0DA58.jpeg15 feet of lovely colas !mostly @genuity ’s fireballs and my nev haze x la con .

This is my 2019 garden. So far the weather in September has been almost perfect here. We have been very lucky this season. I have 2 cookies and chem- green point .soulmate and dream lotus-bodhi . gooey 13 from bad dawg. Good luck with the rest of the fall!!

Happy harvest all!!
