Hey guys,
This has been boggling my mind so i need to ask for opinions,
Its commonly believed that a autoflower with 12/12 cycle yields way less then 18/6 cycle. But in the video "Cannabis Grow Lighting Myths and FAQs with Dr. Bruce Bugbee" at 20:24 , Dr. Bruce Bugbee says "it turns out its not PPFD [that matters], is DLI".
So by watching a DLI chart i noticed that one can have 40DLI with both 12 hours light or 18hours light, depending on the amount of PPFD.
So my theory is: Autoflowers 12/12 can yield as much as 18/6 as long as you increase the PPFD's accordingly (by light distance or intensity).
ie:
18hours at 625 PPFD = 40DLI
12 hours at 925 PPFD = 40 DLI.
So, same yield.. ?
