Hi,
SDS, do you have more input on that?
How?
Do you mean genetically adapt?
From my understanding I would not know how, as i think that would require them to be heavily mutating and also bequeathing those mutations to the next generation.
I think thats highly unprobable, as plants are no haploid bacteria.
Other thing is adaption via epigenetics, -genes get triggered or blocked caused by environmental changes, e.g. light circumstances.
But this would be happening within generation 1.
I think concluding "things" gets quite difficult.
I just looked at the heliospectra link you gave:
So they compare their custom spectrum of 111W to 32W of white led and then say "look our spectrum yielded much more"?
I mean i posted the diagramm hps spectrum vs quantum yield, it clearly showed that hps fits very nicly withing mccree curve, which is the average of like 30 landplants.
And those helios guys put out info telling you the complete opposite.
The plant led selling companies seem to really trying hard to get things not done or are they.
I guess you know the study where they conclude that in "strong white light" added green light can even max out photosynthesis rate more than any additional added red light.
As leaf absorbtion rate for red light is so high, it has the downside that it also gets much faster saturated with it, thats where other wls come into play.
So even the seemingly simple task of just feeding the plant with light isnt just that simple.
I think maxing out photosynthesisrate within a fixed wattage of used power could be more important than minor photomorphogenetical alterations, e.g. that effective intracanopy lightning could have more of an effect then using wether 660 or 630nm.
I wonder how you guys are doing your experimenting e.g. with 660nm.
Do you have side by side comparisons, or have you grown those plants from the same mother for several times and notice the differences by experience?
Adaptation :
Yes ,I mean genetically adapts .Pretty fast and easy .
I'll try to explain ...
From many outdoor grows ,it has been noticed,for example that it adapts from sea-level to an altitude of ~2000 meters ,in first seed generation ( > 75% survivors ).
Yes ,I have indications that what we call simply 'photomorphogenesis' ,
regarding mj ,it triggers really heavy mutations .
And yes , also bequeathing those mutations to the next generation.
A small 'extract' ,that comes in mind...
(...)Today, Cannabis grows around the world and is, in fact, considered the most widely distributed of all
culti- vated plants, a testimony to the plant's tenacity and adapt- able nature as well as to its usefulness
and economic value. Unlike many plants, Cannabis never lost the ability to flourish without human help
despite, perhaps, six millennia of cultivation(...)
(...)Whenever ecological circumstances permit, the plants readily "escape" cultivation by becoming weedy
and estab- lishing "wild" populations.(...)
(...)Such an adaptable plant, brought to a wide range of environments, and cultivated and bred for a
multitude of products, understandably evolved a great number of dis- tinctive strains or varieties, each
one uniquely suited to local needs and growing conditions. Many of these varieties may be lost through
extinction and hybridization unless a concerted effort is made to preserve them.(...)
(...)Nature also calls on the gene pool to ensure that a strain will
survive. As climate changes and stronger pests and diseases appear, Cannabis evolves new adaptations
and defenses.(...)

Experiments :
Stardustsailor's way ...
1st level : Clones from same mother plant ,in same long rectangle-shaped pot ,
with root cloth preventing roots antagonising/mixing-.Same fed .Same everything else.
2nd level : seeds from same strain .Separate-individual pots.Same fed -Same Environment.
3rd level : different known strains .Separate-individual pots.Same fed -Same Environment.
4th level : unknown seeds .Separate-individual pots.Same fed -Same Environment.
Guess what ...
Photomorphogenesis,caused by light -even subtle differences from led lights - in ALL LEVELS-
repeat: IN ALL LEVELS ,show same effects on ~99% of subject plants.
No matter what genetics they carry ...
Totally same effects ...
So...
Talking about mj's adaptability ?
Probably
the MOST adaptable plant on Earth !!!
Almost a ..
.genius ....
