I'm at 35 degN and I currently have 3 girls outdoors.
Two are a couple of fem photo seeds my friend brought cack from Colorado as well as an old Primal Punch mother.
The mother is sexually mature, but she hasn't started flowering in earnest yet. Probably next week.
I typically see flower development at the beginning of August, so I was a bit surprised to have both of the seed starts to begin flowering a couple of weeks ago.
Some of it is genetics-plants can initiate flowering on shorter night lengths in some strains versus others.
