It has been shown time and time again that the whole idea of "Stress" producing plants that are somehow "better" is just bullshit.
**I am merely curious if you took the time to review the article I posted, a peer-reviewed study of abscissic acid application increasing end THC content of both male and female flowers**
**edit addition of link**
There is one exception (if you can call it that) to the "Sress" = bullshit rule". That is the introduction of extra UV-B light waves (which can be dangerous in exessive amounts) have been known to produce higher amounts of THC bearing resin. I suppose you could consider that to be "Doing something "bad" to the plant in order to get "good" results.
I agree in part, if you examine the PAR (chlorophyls & accessory pigment absorption) spectrum both UV-a and UV-b sit well within the active absorption spectrum, but they are obviously damagingly potent wLs. If the trichs & accessory pigments can downgrade/filter/focus the light they may be acting as more than just sunscreen, IE UV, as with a balanced spectrum in general--provided adequate intensity, is part and parcel to IDEAL spectrum for C. s varieties. Just saying, adding UV-b isn't doing something "bad" its one of the "Best" things you could do, as you were alluding to.
I have heard theories that UV-b actually drives the production of cannabinoids, but it appears to me that it is more of a genetic response. I like to think of them as another set of "accessory pigments"--if ya catch my drift. Picture this: HPLC analysis of harvest time variation confirms a spike right before lights on (probably equivalent of sunrise period) and the downslope starts to really gear up around 10-11, lowest at the end of the day. This might explain the 1-3 day dark stretch some people use. The plant keeps thinking another UV rich day is coming, and the old cannabinoid deployment never degraded and is thus still present.
I would like to present another example where stress does not equal BS:
Supercropping or forms of stem abrasion will stimulate the release of PGRs as well as a buildup of hard tissue which will in the end provide the grower with higher flower count with ideal spectrum (reflected off leaves is green/yellow dominant obviously, barring leaf senesence lending to prettier colors of course) as well as a network of branches which are knobby and of superior durability. Supercropping is definitely stress.
Just trying to show that a thread may appear useless at first, but folks like us can meet here, and of course share with others if we so choose.

UV-c is damaging to plants & humans, and all intense light is bad for your peepers---don't forget the shades yo
