6/6/6/6 Light Schedule?

If you used this for veg they would grow slow since the flowering hormone kicks in after 2 1/2 - 4 hrs of dark. I saw plants grow faster when the dark is interrupted about every 3 hrs. The problem for flowering is they need 12 or more hours of uninterrupted darkness every 24 hours. If you are talking about flowering a cycle of 6+ hrs on and 12 hrs off might work but you would have to adjust the timer everyday or turn the light on and off manually.

I have done that. and in my experience it works, I mean I cant tell you the satistics but I mean I tried a thirteen hour veg twelve on two off an hour on and 9 off. they got really big really fast because, and when I switched to flower I did 11 hours on and 13 off. then it went to nine hours on two hours off and two hours on then ten hours off, I had amazing crystral and bud growth. growing to me is nothing but a giant experiment, I love experimenting with growing. this current grow im actually vineing them onto a tressils net with a six week veg.

Hang your bulbs vertically and bare, have those girls climb a vertical trellis for that much time and watch them blow your mind...

Question. Does cannabis flower due to the change in the length of the dark period, or the light period?

what dfo you mean? pics?

"
Marijuana is a short-day plant. As the days get shorter, marijuana determines when to flower based on the number of hours it receives of uninterrupted darkness. It measures the length of the dark period using the hormone phytochrome, which has two states. The hormone’s inactive state, Pfr, occurs when it absorbs red spectrum of light at 666 nanometers. It also has a slight sensitivity to blue light. The hormone changes to its active form, Pr, over a period of two hours when the plant is in darkness. When the Pr flowering hormone levels remain high for a critical period of time over several days, the plant changes from vegetative growth and initiates flowering.
The number hours of darkness plants need to initiate flowering differs by variety. Sativas require a longer period of darkness than indicas because they developed near the equator, where the length of daylight is much more consistent than at northern latitudes, where indicas developed. Some sativas continue to grow vegetatively with 10 or 11 hours of darkness, which usually cues most plants to flower.
Many sativas initiate flowering only when the dark cycle increases to 12 hours or more, which occurs September 22 in the Northern Hemisphere.
By contrast, most indicas flower with 8 to 11 hours of uninterrupted darkness (13 to 15 hours of light). In southern tiers of Europe and the U.S., a few indica varieties flower as early as June 22, the shortest night of the year. For this reason, outdoor gardeners in these regions should consider sativa-indica hybrids and sativas. In the central and northern tiers, indica and indica-sativa hybrids usually start flowering in August and are ready to harvest in September through mid-October.
Some sativas and sativa hybrids require a longer dark period at the end of flowering to fully ripen their buds. Outdoors, this happens in due course as the nights lengthen in the fall. Indoors, change the lighting regime to 14 hours of darkness/10 hours of light to promote ripening. This is especially helpful in finishing low latitude varieties that don’t reach maturity in their native lands, where there is no winter, until the middle of the short-day season."

For cannabis photoperiodism is noctoperiodism (what matters is the length of the night, 6/6/6/6 would effectively mean vegging with short days).

Exactly. So by looking at the most basic aspect of growing cannabis, how do you plan to get your plant flowering when you're using the same dark period you use when vegging?

But isnt the dark period the same you still have twelve hours of darkness. Just not a full 12 hours of it. When vegging you only have six or eleven hours of darkness. How is that the same dark period?

I just don't understand how it wouldn't work.
