How often can weed flower outdoors?

[Southside112]

I know that weed flowers late summer. I have also noticed they flower and finish around this time of year. I have a plant that I started like a month ago for the fall harvest. This plant is in full flower atm. Also found a plant around this time of year in my yard and it was ready to harvest. Was fire as well. So am I correct in assuming weed flowers twice a year? Thanks.

Short day flowering plant.

With less than 11- 12 of darkness it will stay in veg.

Day length is related to latitude.
I am far enough North that mid summer, blackness never arrives.
East horizon starts glowing sunrise at 3:20 AM

Plants in my backyard will stay in veg until the last weeks of August.

def can get an early bumper, if it is close to finishing around 16 hrs daylight you prob won't deal with reveg at all, between 16-18 hrs it will speed up finish I've noticed but if it keeps flowering after 2 or so weeks into that range it probably will reveg...but if you pollinate for seed they will keep forming too.

Whenever I move, I have to pinpoint the dates again for example mid August I hit 13 hrs of daylight...then have to average first frost dates and average snowfall from there...to get an idea of flowering window...if that's a short window I'll be looking at last frost date and when the beginning of season hits 14hrs daylight hours..

You could also have some fast photos...especially if the beans came from an indicator hair at the node, those beans always seem to flower fast or in the least trigger with 14-16hrs daylight, at least from what I've observed

From my experience it seems to vary according to strain. I have a popular strain that the 'seed breeder' (actually stole from someone else)
says routinely can be harvested 3 times. I myself have another strain which is a personal favorite of mine that I have harvested 3 times and bless her heart she is currently throwing new leaves.

Answer: I don't know. Do you have any experiences?
