6 on 12 off .....anyone??

[shankae]

Just wondering if any body has tried 6 on,12 off whilst in bloom before??
Been trying to find out more info on it but have been unable to so far.
Very curious if there are any benefits to this procedure?

I think if you grow with less hours of light you might slightly higher content of CBD, but I think your 6-12 is too radical, if anything you will be growing a 2 months strain in 4 months

[h=2]Growing with an 18 hour Day/Night Cycle[/h]

The Theory The theory behind the 18 hour Day/Night cycle is that during a normal 24 hour light cycle plants will usually acheive 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 acheives 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. ​

So what do ya reckon?? Any one willing to try it??Im in the middle of one at the moment but am thinking of trying this next.
Anyone else tried or heard about this??

 

[shankae]

cmon anyone???????

do some searching, it's been discussed a very lot fairly regularly. If the riu search gives you trouble just search riu through google and use some Boolean operaters (sp?). Happy hunting!


Ah and while searching you should look up the use of far red during night to manipulate pf and pfr proteins to allow for very short nights (like 1 hour).

Some neat stuff out there, much is beyond me at current.

im always skeptical of such claims if they dont bother to show it works. if theyve done all the testing and such to come up with that why cant they show it and end any possible skepticism is my thinking.

Umm OK,I was actually just asking if anybody had done it or heard about anybody doing it as I dont.
I AM going to try it when my current grow is done and I will post my results here.Thanks

 

[darkdestruction420]

i know all that. i read it in your posts. you said "So what do ya reckon??" after you posted the theory walkthrough/guide/whatever you want to call it you found. I looked it over and gave my opinion. it's worth a shot to try if you want to try it. i would be interested in the results as well. if you do go through with it i'd like if u sent me a message and link to the experiment.

 

[shankae]

HAHA ok i was reading your message at the bottom of your post and I thought you had written that to ME.sorry.
I thought it was.......rude.......hahaha.And I thought to myself WTF this guys having a go at me for....for what???
So yeah sorry.
Yes I will send you results. will take a while as have flipped the switch on my grow about 2 weeks ago.
But keep an eye out for it.

as ive stated in my prev posts ive done 6/12 for years cuts heat was my reason =money saved less ac to run etc 7 days =91/2 days when running this cycle bonus too this method bumps up gpw huge 1m tryn get 3.0 gpw but 2,5-2.6 gpw totally obtainable

I'd really like to know your strain/lighting/medium/nutrients/ph/magic. Getting those numbers(gpw)would be pure gold for me(i'm a personal smoke grower). Seriously, if you are getting 2 gpw, I want a link to a grow you are doing. Everyone wants a link to that grow as a matter of fact. Please, for the love of Ganja. Please do a journal.
