10/14 lighting in the last 3 weeks.

I have heard that in the last 3-4 weeks of flower, you can switch to a 10/14 lighting schedule and it will help to finish off the plants a little earlier with nice resin production and not sacrifice much yield.

Anyone ever used this before?

bump diddy bumb bumb bumb!

i am flowering with a 400 watt hps at 12/12 for about 3.5 weeks as of right now...

I plan on switching back to my MH bulb weeks 6-8 and only giving 8hrs of light, and go severely low humidity... this from what i heard will bomb resin production to a ridiculous rate...

Then in my last week I am going to go back to hps on 12 hr schedule to amber the crystals and harden off the plants... My hydro shop guy does this to good results and told me to do it...

anyone disagree, or agree for that matter?

Hope that answers the question

I wa talking to a friend the other day and he told me that if you put your light schedule from 12/12 to 8 hrs light 16 hrs dark (for 2-3 weeks before harvest like u said) that your buds will get sticky and more dense. ne1 else here this?

I've heard it will speed up the end time. Haven't tried it though, sorry. Give it a shot if you need to otherwise, let it ride...

I have read in the growers bible about that 10/14 and they say no good, but as for the rest of the forum talk and what your hydro guy says, Its allways worth a shot so you know for a fact if it works or not, and please let me know what happens.

If you do it from the start of flower, then you will for sure sacrifice yield, but if you stick to 12/12 until the last 2-3 weeks and then go to 10/14 the plants should finish with really nice resin production from what i have heard. And with almost no loss in yield.

I'm on day 27 or so and switched to 11/13 today, and in about 7-10 days will move to 10/14. I figured this would be a nice little transition, I will let you guys know what I think.

DwR scratches head

I need a new grow tent, want to try this out on some plants and others I want to still remain in the 12/12...

Will be watching......

I am interested.. I may try this. Only on day 6 of flowering at 12/12 and my three plants
are 19 - 27 inches for the largest of the three. I've been thinking about increasing the dark and lowering the light hours slightly.

it doesnt work

Well according to Ed Rosenthal it does work.

" Cutting the light cycle will hasten the ripening of the plant, there are reasons why it may be more important to speed up the ripening than to maximize the production. Under these circumstances a 10/14 light / dark cycle could be better". ----Ed Rosenthal From the book. ( Your marijuana questions asnwered.)

Sounds like you might be wrong man.

In my case I think this may help, due to the fact i veged out my soil plants for almost a month and now there HUGE... almost as tall as me!

Anyways i will let you guys know what I think in the end.

Thanks,

it still doesnt work

???! Proof that it wont work?

he doesnt have to he's the authoritah lol...

Yeah it works, the science is pretty clear and vivid. It takes a simple understanding of how the THC disc cell leaks secreted fluids in process that ultimatley converts your clear trichromes to a milky cbn and cbg filled mixture- at that mixture there are also 3 other CB cannabinoids- but suddenly- they all break down and only the CBN CBG and a new compound THC are formed... That curiously, happens in the dark...

Thats the science, thats the warrent to my claim...

oh and if the proofs in the pudding,
YouTube - THC, UVB and Me That one explains the science of how THC is formed and light and humidity or rather the lack there of increase the production of dankness!

YouTube - The Grow Show - THC percentages, do they add up? (part 1)
that video is part one of a three part mini series by marijuana man, arguing that the calculations of THC are flawed, it also uses a scientific analysis of how the THC is formed, while the jist of his lecture is not on reducing light, if you understand science you will see they are quite complimentary ideas...

https://www.rollitup.org/toke-n-talk/77491-truth-about-thc-percentages.html
That was a forum I started later to explore the concept of THC percentages.

But yeah your wrong, really wrong.

You gonna lay your badge on "still wont work", authoritah around these parts...?

why not just do the lights off 24-36 hours before harvest, sort of the same principle but your bud has already grown out. I would think that by now that light cycle would be proven and tested by many growers, but i don't hear about it, so I really wouldnt want to try it, but if someone has got a spare room and is going to "experiment" it, I would like to hear the results

Not very many people want to experiment... Everyone wants someone else to try something new while they grow the tried and tested ways. Even when someone comes up with a good experiment and shares, all the tried and tested nay sayers come out.

well not everyone wants to try something that might not work and may ruin their yield, Its the human way to learn from others. The only way to really experiment this would be to have clones grown in the exact same conditions with the different light cycles and comparing the end result, which the normal pot grower usually doesnt have the time or the resources to do

Is this a joke? Or are you a joke?

If you used 10/14 from the start of flower to harvest you would lose yield vs. 12/12. But if you switched from 12/12 to 10/14 from mid to end of of flowering you "could" hasten the repening of your plants.... end of subject.

Infact, some "guru's" say when flowing pure sativa's indoor's to "spur ripening"

"You shold leave the plants in darkness for 13-14 hours daily. Because equatorial strains do not respond to lighting cues as forcefully as higher latitude plants, they do show better response to longer dark periods".

Just saying something does not work without stating why is stupid man, we are all hear to learn.

Thanks, Comercial

So I switched 40 of soil plants to 11/13 today and 53 of my hydro plants to the same 11/13 after only 7 days of veg on the hydro.

I will go to 10/14 in about ten days. on both hydro and soil. I will let you guys know how it works with pics and of course my opinions ect...

I should only be losing about 15% or so of my yield, in hydro and maybe non in soil, from what I have read.

I have always done 12/12 and will determine honestly how it works out in the end.


Thanks,
