Low - how were the results, and how much do you think the lighting contributed?

Anyone here have enough space for two small grow areas to test this? Start with 2-4 girls in each with the EXACT same set up (lights/space/temp/humidity/ferts/water/air flow/co2/etc) but do one with the norm 24/0 or 18/6 then 7/12 on the one, with the other being the new suggested lighting. I'd like to see the difference in veg first, and then flower second. I can understand the flowering in many ways to be increased with the shorter light periods - most plants don't get concentrated light for THAT long each day anyways.

Hmmm - any studies that people are aware of for the ideal number of hours of direct sunlight the plants need outdoors? Roses prefer 6+ although some do very well with 4+ and then light or total shade the rest of the day. Some plants only like 2-4 hours direct at most. What about cannabis? What is this plant's preferred light intensity? That could signal how long they really need lights on at a time.

Also, does it matter that much to the veg time if it's 12/6 or 16/2 or 24/0? There are some people that do straight 12/12 for seedlings even, so... I don't really know. Anyone?
