An experiment to help determine the effect of different latitude on maturation time using a select cultivar

Here are a couple of pics from another friend growing Miss K at 55 North on the cloudy coast of Alaska. It looks like it is slightly later to start flowering there.

the plant just flips a switch at a set photo period regardless of latitude.

This made me wonder when the photo source is the sun, can the variability of light duration and intensity etc. hitting the plant be a factor in onset of flowering for a particular clone from year to year grown in the exact same location? For instance, some years there are far more rainy and cloudy days than other years.

A variation of that situation; maybe your zone is really sunny and that same plant grown about the same latitude, but different longitude has a wet dark summer...which flowers first?

Also, sort of within topic, do the nutrients or root zone (pinched in a small container vs in ground, lots of root space ) have anything to do with timing of flowering?

Thanks for starting this thread, good exchange of info. and opinons.

Yes I too thought of other factors .I was confident that the plant would sense the more rapidly decreasing daylight at higher latitude and respond with more daylight
