Hello k0jin and all other members who have made this thread the most informative I have ever read!
It has come to my attention that the "color of light" has a tremendous effect on bud growth, ripening
of white pistils to orange, as well as the production - quantity/size of trichomes.
I have also noticed that the aging of trichomes seem to be similar on the same plants using the same
hydro reservoir but under different 12/12 bloom lights.
So, I have come to the conclusion that the color/quality of light plays a dramatic role in the pistils ripening,
but not so much in the aging of trichomes.
As far as I can tell, the more blue spectrum - 480nm, 460nm, 440nm, 415nm - you have, the longer it will take for the pistils to turn orange.
Some people may think that it is a specific genetic trait of the particular plant that controls this transformation, I have found it not to be true.
Your thoughts?
Hello OneloveGrower,
I'm not quite sure what your questions are but it is correct that the colour band is relative to how plants grow.
For example the 380nm - 400nm range is the start of the visible spectrum and is the band range where chlorophyll absorption begins.
The 400nm - 520nm range is where peak absorption of chlorophyll is observed, it is also the range which promotes
vegetative growth.
The 610nm - 720nm range is the red band of the spectrum and is the band which promotes
flowering.
The range in between 520nm and 610nm includes green, yellow and orange bands, and has far less pigment absorption.
These range bands directly relate to the colour spectrum which is why you might have read about the violet, blue & green bands referring to vegetative growth, and why you've might have read about the red band referring to flowering.
The points you bring up are from home experiments I assume?
Do you have any scientific research which backs up your theories or are you just sharing your personal findings?
The reason why the violet/blue part of the band affects how quickly the plants (including the pistils) matures is because that band range promotes growth, not flowering/budding, vice versa with regards to the red band.
This is also why growers use specific lights which promote the kind of growth or maturity that the growers want.
Just make sure that you remember the difference between the wavelength and the colour temperature (measured in Kelvin), it can be confusing if you don't remember that they are two different ways of plotting colours in the spectrum.
