Yes your correct, however there is concern with excess stretching if there is an overabundance of far red during the day cycle. Warm white cob lights do emit small amounts of far red. Doesn't neeed much additional far red.So where am I going with this... With this said, Wouldn't it be beneficial to run both 660 and 730 during the entire lights on period and then JUST the 730 alone for 15 minutes after lights out? This seems like it would give you both the benefit of increased photosynthesis during lights on, and then faster transition to dark period, allowing 13/11 or even 14/10???
Am I correct in thinking this or am I wrong?
