PFR 760nm to 800nm activates the shade avoidance response in plants and causes stretchy growth and further node spacing.
The ratio between red and blue light in the 400nm-700nm range effects growth as well.
Oh yes, longer not shorter. I even gave it a second look myself, knowing it wasn't right. Since 40 I have been making silly mistakes. Since my mid 40s, daily. Now pushing towards 50, I can see myself in a mental institution before long.
So it seems the plant is watching the two, and when the longer more penetrative light is arriving with greater ease, it knows to forget making buds and to shift it's arse into gear.
Shit man. Christmas and new year have ruined me. I don't remember where I was heading. I can just about relate water coffee and sugar. I have been sat looking at a green light for about 5 hours, to do further experimentation growing without either, or anything really. I just can't get my shit together though.
I give up lol
