“Some of the commercial growers I work with have seen great yield improvements recently by using long flowering photoperiods of up to 16 hours.
This increases the DLI by 33% without requiring additional lighting infrastructure.
My recent article on Cannabis Photoperiod Hacks has more detail about the science behind cannabis photoperiodism and flower induction. I hope that you find this useful!“
There is also the opposite spectrum of decreasing your flowering time through tried and tested “gas lantern” lighting periods. Lets share new methods, concepts.
Very interesting 
I know growing Flowering plants in the greenhouse for the florist trade
we would give long day flowering plants a hour light at mid night or give short day flowering
plants a hour of total darkness at mid day
so you could flower long day plants in the winter and short day plants in the summer
all the best and be safe

It saves money and works!
Hmmm, never heard of this.
Hi, I’m a first time grower with only one plant (Trainwreck) and I’m just now ready to go to flowering. I’ve been on a 18/6 schedule up to now and plan to go to 12/12 over a period of three or four days. I appreciated your Photoperiod article, as someone threw out “photoperiod” to me in a comment and I had no idea what that word might mean! So much to learn. Thanks for the lesson.
Some plants can yield more under 14/10 but some also had reduced potency but if your growing for extraction the extra biomass should make up for the slightly lower potency
