To speed up flowering by changing your light cycle go with 6 hours light and 12 dark, an 18 hour day. You get almost 3 x 18 hour days to every 2 x 24 hour days, You won't harvest quicker at quite that ration but you will harvest quicker. Some yield will be lost.
.
Other ways to speed harvest:
- more light
- low kelvin light (red)
- air pruning buckets
I'm going to do some experiments with far red light in the last hour of normal light and for 30 minutes after lights out to see if the emerson effect speeds flowering / increases yield / increases potency.
