6/12 bud

[weedyoo]

so is any one else doing 6hr days and 12 hour night in thus that every day is really 2 days, well 2 day cycles so in your plant only mesures cycles and not hours.

i am on my second week with this cycle the only thing i have noticed is i have bud sites in 2 weeks when it usuly takes me 3 weeks to see them.

so i need a 14 day 220v timmer been doing it with 24 hr timmer so i need to set it every day but.

Interesting concept. Why 6/12 though, I would think day/night timing should be equal as with 12/12. Maybe 8/8, so you get 3 cycles every 2 days.

Take note: this is just a suggestion for an experiment, most likely won't work, but would be cool.

no you need the 12 hours of night to force bud

 

[RinceW]

Yeah, longer nights cause the flowering hormone to develop

It would seem that the less light during the day would mean less bud growth. right?

well you still get the same amount of light in 24 hours just separated by 12 hours of night
so you have 6 light 12 night 6light

12 /12 just not the whole 12 at a time




now i read this here and on anther site but now i cant find it.

 

[RinceW]

so its like.. light/dark/light every day? thats just off settings it by a few hours

 

[darkdestruction420]

Yeah, longer nights cause the flowering hormone to develop

this made me wonder, once i get like halfway through flowering can i go and bump the lights up to like 15 or 16 hours?

Nope.
Extend that formula for a three day run:
Monday 12 AM: 6 ON, 12 OFF, 6 ON
Tuesday 12 AM: 12 OFF, 6 ON, 6 OFF
Wednesday 12 AM: 6 OFF, 6 ON, 12 OFF

12 hrs light for the first day,
6 hrs of light for the second day,
6 hrs of light for the third day.
You'll lose 12 hrs of light in that 36 hr span.

You've added an extra "day cycle" by lowering the plants allotted time to convert food.
It seems off to me.
The more the plant can process, the better.
More materials, a bigger house. More slop, a fatter hog.

i smell hermies but what the fuck do i know i say try it

sounds like someone feed you a load of shit....but for real i got some seeds for you they only need two hours of light a day from a flash light you can get a pound if done right....pm me...lol

Stressing your plant out by changing the light cycle daily will stress it out and (may) cause it to go herrmie' or any other types of stress....seacrest out!

I just read about this the other day. Here's a C+p about it. Sorry forgot who orignal posted it, but I saved it on my CPU cause I wanted to try it as well. From the sounds of it, it will not stress your plant and cause it to hermi. The uninterrupted 12 hour dark cycle is the most important and shouldn't be interrupted. That will cause hermis.

Growing with an 18 hour Day/Night Cycle

The Theory
The theory behind the 18 hour Day/Night cycle is that during a normal 24 hour light cycle plants will
usually achieve high growth rates peaking at 100% capacity during the first 50 - 60% of the day. The
growth rates will then diminish rapidly and the last 20 - 30% of the day achieves minimal growth. So
by reducing the length of the day we are triggering an increased growth mode where the growth rates
are at their peak for the majority of the day. This effectively achieves a very fast growth cycle with
full yield potential.
NOTE: To achieve these incredible growth rates it is important to provide maximum light intensities
and CO2 enriched conditions. The recommended lighting is 600W per square metre.

The Cycles
Vegetative Cycle - Lights ON 14 hours, Lights OFF 4 hours
Flowering Cycle - Lights ON 6 hours, Lights OFF 12 hours
The Benefits
The growth acheived during an 18 hour cycle can be the equivalent to that acheived during a 24 hour
cycle. So by running 18 hour cycles the same growth and yield can be acheived in 75% of the time.
Reduced day lengths also mean reduced power consumption. Grow more and use less power. Who can argue
with that?
For example, an average crop grown from seed using a 24 hour day/night cycle will have a 4 weeks grow
cycle and an 8 weeks flower cycle. This equates to 28 days @ 18 hours a day and 56 days @ 12 hours a
day = 1176 hours of light over 12 weeks.
An accellerated crop using an 18 hour day/night cycle will achieve the same yields using a 3 week grow
cycle and a 6 week flower cycle. This equates to 21 days @ 14 hours a day and 42 days @ 6 hours a
day = 546 hours of light over 9 weeks resulting in a 40% reduction in power consumption and a 25%
reduction in crop time.

Here's where I first read about it. Thanks Hobbes for the quote above.

no no no

you get two 6 hr days in one day 12 hours of light just split by 12 of night

so in one day (24h) i get two days

and again no no no you dont ever chang 12 off


my plant is still prossing the same food its just getting more days and night


some where on riu theis a dig thred on this but the search on this site sucks.

 

[RinceW]

okay, but if you like, have 6 hours of light every day at the begining, and six hours of light at the end, dosen't that mean that really its just a 12/12 cycle?

 

[cookin]

definately worth a try, i've read all that stuff about plants being most efficient at the beggining of each period so maybe, but as someone has already said you could get hermies, still try it. also i know you say they'll still get the same light, but it could speed up the cycle, don't know how adaptive weed is but instead of getting used to it they could just blitz the whole flowering bit and you end up with less but quick, don't know you'll have to see if it outweighs all that efficiency stuff(if it really is true). Let us know when you finish how it all turns out

no, you're looking at that other guy's post who got it wrong. the title says 6/12, so its an 18 hr cycle.

I have noticed the same thing, the plants grow fastest when you first hit them with the light. This might be worth an experiment if someone is willing.

yes but with more days and night in 24h i get 2 days
