lights on 11 - off 13 Advice needed.

15-8 was being sarcastic dude , 13-11 ,you understand . your advice is complete shit . your wrong , turning the lights from 12 dark -12 light to 13 dark- 11 light will make the plants mature quicker ( fact ) . Probably done bigger and better grows than you think . You been reading too much shite and not doing much else methinks kiss-ass

If you already know it is FACT then what did you want when you asked if it would work, attention?

correct spectrums? doesnt matter, if you had correct lighting spectrums and it was intense as an hid then your plan would have fastest chlorophyll production and resulting in faster flowering time, this is not going to happen as leds havent reached that intense of light yet, 11-13 is stil pointless whatever you do, the plant does no bud growth whatsoever during the dark period.

if you had the correct spectrums 100% then why take off hours of daylight for the plant to sit in the darkness? you could run a 13-10 schedule and have flowering times shortened dramatically. 11-13 no matter what you do is a waste of growing time, unless you want to save 20cents a day.

if your plants are flowering for 11 hours of sunlight a day then youd only have around 9 hours growing time when your plant wakes up it has to convert pfr back to pr which unless you have far red lights, (700nm-720nm). so everyday that you use specifically just a normal hps 2100k 630ish nm? then it takes ~2 hours to convert pfr back to pr and then flowering will continue.

There are too many variables to give an answer. Different strains, water, temperature, soil etc. Plants grow by filling the newly divided cells with water. If the plant has insufficient water it will either not grow or grow slowly. As a result many plants do indeed grow faster at night because the amount of water available in the new growth is higher. Plants also need sugars and other nutrients to grow. So some plants grow most rapidly in the mid-late afternoon, when the water flow carrying nutrients to the leaves is highest, and when sugar production from photosynthesis is at its peak. There are huge numbers of other variables as well, not least of which is simply when the plant is genetically programmed to grow. So it’s impossible to generalize on when your plants grow fastest.

i agree almost 100% its all dependant upon the plant, but information i provided isnt strain dependant, it can be done with any strain, correct lighting spectrum will give the maximum chlorophyll production possible and this is all dependant on if your plant is healthy enough to utilize it all. it just sets the bar and then its up to the plant wether or not its able to use the light to its full potential.

chlorophyll production and sugar production is only done when the light is there for the chloroplasts to absorb the light.

also i only suspect people who know what is being said are more experienced horticultarists and not your run of the day grower.

theres a wholeeee lot of misinformation on the first page of this thread....

was asking for advice , not some fucker that swallowed a book on lighting who tells me to do research and gets my back up straight away and tells me shit as if he's superior putting me down . Done many commercial grows and need to speed this one along thats all. Nice to be Nice dude. Attention, give me a break, just fuck off man , not interested in you putting your nose in.

There is no efficient way of speeding along a harvest, continue with your regular flower cycle and cut them when ready or when need arises; you may lose some weight and/or potency but changing light cycles will not save either.

regards,

I tried 13/11 last time and for some reason the buds were bigger and the plants took longer to ripen than the last time. I just figured the extra hour per day added up to more focus on growth and less on ripening. Trouble for me was I also changed food so I can not attribute the added growth or slower finish to just one thing. Also it was a different season so temps were slightly different as well. In my mind it would make sense that less light would send more flourigin (sp) What effect that would have I do not exactly know. Interesting topic though really.

Increasing the plant's dark/night period more than it's light/day period will make the plant taller, spindlier (etiolation), and (most likely) yellower. This is a fact. The increased height is the plant's natural response to "low-light levels." Basically, the plant is trying to outgrow whatever is blocking the light. When I grow a sativa or a hybrid that's more sativa dominant, if I'm able, I often run it about an hour longer with light than without light. It slows down the plant's genetic "desire" to stretch as much. You'll end up with a much shorter and compacted plant.

fuck all to do with this thread but just realised that you said that you give your plants grow nutrients throughout the bloom to stop all the shit that happens so wish i could give you rep for that coz its the way forward , saved a harvest so nice 1..

I use the 12-1 lighting schedual for veg, switching to 11-13 for flower and reduce light by 15min a week. Heres what I HAVE noticed:
In veg, plants grow just as fast but not as tall, they stay fuckin tight and crazy compact. No stress. No hermies. Legitamate. And less time on lights which saves.
In flower, nothing remarkable yet? Except i got some thick buds forming already. These are gonna be some nice nugs. Sugar down the fans (Not the huge fans). Also smelling good. Strong. Im excited
Ill contiune to lower the time each week. Unfortuantely, This is my only grow with No complications. All my previous grows were ravaged by mites or mildew (this is only my third grow >.>). So i have nothing to compare to except that i got 2oz off a 4ft strain that im growing again.
Either way, its legit so far looking like a couple ozs per plant already.

Repeating post #14, so you can read it again. Keep reading it until you understand it.


Giving your plants fewer hours of light per day does not make them finish sooner, or think that winter is coming. What it does is cause less THC to be produced. Rob Clarke says in MJ Botany that giving plants 10 hours of light per day results in half as much THC as 12 hours of light per day.

Thats an incredibly long flower time, if you didnt fuck with the lighting so much, and didnt interrupt the plants sleep cycle, you probably would not have noticed the stunt in its growth. you screwed its photo sensitive period up and thats probably why its taking too long to finish its harvest. stick to the basics, especially if you do not know what you are doing. get some LEDs that specialize in the spectrum around 650 nm to ensure the best photosynthesis, as a supplement to surround the other lighting you have. otherwise you cannot change the light cycle that far into flowering without noticing a huge stunt in growth.
