You cant trick a plant, that has evolved for thousands of years into thinking days are 20 hours long. Its hard coded. You can try, but you will have some interesting results. (AKA, a fat bunch of hermies). Considering you are only shortening the day by 4 hours. You may not get many side effects. Try it. Maybe try 11/11. A 22 hour day

You've got to keep the dark time around 12. If you do that, you can vary the light time any amount you want; but if you lessen the light too much, it starts affecting the yield pretty considerably. Haven't done it, been reading testimonials about it for years.

There are peolpe who say you can make your plant flower faster (less time) if you make it dark for loonger gradually over time. It makes the plant thinl its almost winter and it finishes faster. I have never done this so cannot say for sure if it works. I am patient but thats easy when you have jars full to smoke! Much Love!

commercial egg producers will keep their chickens on something like a 12 hour day to get twice as many eggs. Perhaps it may work since the ratios of day and night will stay similar causing them to lose no light except for the early flower.

3 years ago i did a test. i thought i could speed things up with 18 hour days.

my light cycle was 12 on 6 off. First problem was mastering the use of digital timers, second problem was it was crazy trying to keep up with the flip flop schedule.

on Day 55 of flower the plants were not finished, this was the adverage day to set buds from this line. i allowed this plant to go 67 days of 18 hour days, this was still shorter than the 24 hour cycle, however you could see a dramtic loss in yeild.

you can shorten the days, however this will kill you, if you only give 10 hours a day, your plants will likely get very tall and lanky

If you want plants to flower fast, put them in dark for 24 hours when you first flip them then put them on 12/12 Keep on 12/12 until the plant is right into putting bud on then you can change it to 14/10 then when your happy with the bud size put them on 10/14 until there ripe. Any time you start changing light cycles there is a major possiblility of hermies depends on how stable the strain

I agree with Whynot?? except i put them in 48 hours of dark before flowering, then I started to get lazy and forgot to turn them on at all before going to work, and reduced the light time to 10/14. As a result they finished flowering after 7 weeks when the strain was a 9/11 week, so basically I reduced it by 2 weeks. Word of WARNING this reduced the fuck outer my yield, I was very disappointed and wouldn't recommend it!
