dont answer that^ anyway im glad to see that there are other people growing in montana besides myself!
I wouldnt recomend growing outside in our summer/fall becauase it still gets to about freezing at night.
We used to have a cannabis cup entry every year with a strain called gallatain green, and it was grown in the mountains up big sky.
so its def possible, however G.G was genetically modified to withstand the cold.
i know its not recomended but i know alot of people that leave their plant outside for 12 hours, then when it gets cold they bring em in.
i hope all go wells with your grow btw. represent big sky country ahaha
