I'm in Minnesota it's the 13th of July and my 5 foot mothers are flowering and have been for 5 days, how long til flowering stage is complete? Just a regular 8 to 12 week thing?

Will I have to wait til mid fall right before the first frost? Or could I harvest them whenever they look like their done?
