Another node spacing topic

I read somewhere on the internet a few days ago that node spacing is light and heat based. In springtime, when there are huge gaps between day and night temps, more node space is created. Same thing when 1st switched to 12/12. Is this accurate? I am asking cause if that is true then I could use a heater in my grow tent during lights out to keep it from stretching as much so I could veg my plants a bit longer. I will try to find it again and post a link. Thanks.

Happy growing.

My understanding :
In spring the plant exposed to sufficient blue light doesn't need to stretch, and thus have tighter node spacing. Plants needing blue light do stretch and increase node spacing in their attempt to find blue sky.
