Sounds reasonable, but I myself don't rely on the numbers them self. I go by what the plants tell me. Not that I'm dissing the science, just that there are too many variables from garden to garden to actually put a certain number.

But are you actually growing cultivars that are acclimated to the intensity of outdoor lighting or cultivars that through generations have been raised and propagated by HID lighting. Just my experience with plants morphological ability to adjust and change to their environment factors over time in that environment.They are telling me something is wrong and i think its the lights. They’re just too bright and plant just gets pulverized with 40+ moles per day. As i said some plants may like it even. Sativas should love it for example but this one doesn’t i think. Co2 would help also which i don’t provide.
So afterall what is it? 8hrs or 12hrs? The dli will be higher with 8 hours :). Shorter photoperiod but more photosynthesis so shouldn’t diminish yields in theory.

Good discussion anyways, good talking with knowledgeable growers.
A lot of variables as I said earlier. First most cannabis plants are lucky to get 5-7% of their inputs to turn into plant matter. Where, if my memory serves me right, tomato plants are 10-12% efficient in turning their input into plant matter so almost double in term of plant matter production per units of input compared to cannabis. Hence why you can feed a tomato plant 2.1+ ec and not skip a beat, feed a cannabis plant 2.1 ec and we both know what'll happen.
Over all, and from my experience, best trich responses happen in lower light intensities the last 2 weeks of flower.
Did you read the PDF ? Notice what type of lighting they used and the spectrum?
(Model LI-6400-02; light emitting silicon diode; LI-COR), fixed on the top of the leaf chamber and were recorded with the help of quantum sensor kept in range of 660-675 nm, mounted at the leaf level.
Blue and red LED's or the old blurple's. Not white full spectrum lights.
I'm not against Science, it just most research focuses on single inputs or only a few processes during their testing. If life was only that simple, we would all have it made.Yeah but umoles are umoles. Again, a guideline, not something to set your environment to.
But i do see they used a mexico originated cultivar. So its probably more than properly adapted to high ppfds.
