@hawkman I found my copy on Amazon but it was a print from the 80’s maybe? I don’t think everything in the book is accurate but I dont think he’s pushing fake info just a product of the times. his legacy speaks for itself. His descriptions of different landraces are pretty spectacular and makes you appreciate how much work has gone into modern cultivars.

I also appreciate very much DJ Short, although to me Blueberries doesn’t smell 
Anyway:
I found more and more post where people mention things like: " certain strains will do better then other under the same light conditions"
Regarding the Italian article to me there is something doesn’t match properly, although I found another article ( not scientific research) called: " what to know about lighting cannabis" where is displayed this diagram of intensity of DLI during different stages.
It seems that actually the demand of light diminish during flowering ( as it happens in nature actually).
Any comment?

Yeah that diagram certainly makes it seem like the weeks leading up to flower are when they are the most light hungry. I am not too surprised though, the foundation laid in veg likely determines flower yield.
I have seen a few papers looking at growth rate through an outdoor season, and the growth rate does tend to increase before switching to flowering. Its always reminded me of the critical weed free period in row crops; the idea that plants are most susceptible to competition from weeds until a certain point in the crops development.

A lot of people reduce the light intensity at the end of the flo, either by shortening the day cycle or dimming their light. Helps to finish faster for extreme sativas. Guess it triggers a “this the end” signal in the plant. You can see the opposite, when there’s too much light at the end of the flo, some plants seems to go on flowering. Foxtails you said?
Apply the right light pressure to select your favorites, take into account the inner genetic distribution chaos and roll the dices. You’ll be breeding for light

Diming the light , reducing temp , lowering p , all these togeather help finish the plant , your taking away what the plant needs to keep flowering with its reduced hormones , so no foxtailing

I think the best quality pot is grown in the shade under the trees. Must be the far- red.

Yea ! how true – at that time there wasn’t to much in pint – then again he is noted for “blueberry” and gets credit to be a great clutivor - it’s interesting reading “old” publications and take note of all new information in cannabis (it was re-born again in the late 90’s )

I was reading again the archive of BCGA and fund this article about UV supplement.
Interesting thread with OT1 and High Vic and other comments.
Full link here:

Some extract I guess it’s interesting for this thread.

All these new strains are made with kick ass lightning, there are no seeds breedders that are using fluo lightning so the plant after regenerating with so much light all his life tend to include this trend in his genetic pattern. They don’t breed seeds for low light level YET>
There are some older strain like NL that work well under low lightning […]

Thanks for the challange, it gives me reason to take the time to explain further 
Basically, under non selective pressures I agree with your point 100%. However, artificial selective pressures are at play here. Also, I agree, simply creating your seeds under high UV conditions will have little effect on future generations, you will just get more potent seedy buds. You need to use the UV in your selection process, this is where change can occur. My argument will make a few assumptions that are open for challange though, hehe.
First, lets consider THC’s role and effects on a plant’s overall health. It can be good or bad for a plant depending on it’s location, for example, a low THC plant growing in a high THC environment is going to spend alot of energy repairing tissues damaged by UV. Therefore, it won’t be able to be as vigorous as other plants with high THC. However, a high THC plant growing in a low UV environment will waste alot of energy producing THC, energy that could have gone to faster growth. Therefore, vigour could represent opposite traits depending on the environment.
And the most vigourous tend to be what we and nature selects for. In our case, our selection pressure are much more extreme because we work with much smaller population sizes. What would take nature hundreds of generations, we could do in half a dozen or less. Cannabis has enough genetic variation to allow this.[…]

Breeding for light means breeding polygenic.
