Whats ur take on reducing to 10/14 light schedule for quicker harvest

[Joe Blows Trees]

I've been running 11/13 for a while now and it does bring out some nice pheno expressions, but my yeilds are not as good as when I ran 12/12. When the next bloom group is ready, I will run half 11/13, and the other half 12/12. That way I can see the yeild difference, if any, and pay special attention to pheno expressions and plant development. Glad I read this thread.

You should definitely try the split! I had the same issue when I ran 11/13 the whole time but doing what I do now where I gradually work my way to 11/13 my yields are what they should be again.

Bad info Killa, added a month to a grow I ran last year.My Indicas have a 6 -8 flower period and it took every bit of 11 weeks rather than the usual 8.

sounds like a bad ideal.at 12/12 the plants know its time to flower. a shorter day would give them less energy to use growing and may actually increase flowering time. seems like giving them a brighter light may lower flowering time. but each strain is different so you will just have to try it with the strain your growing

BS - "killa"! Shit tons

of evidence to the contrary!

Doing such for the last week or 2 on a 7 week plant - will add NO time to the finish time!
In fact, doing so from the flip,,,,,will shorten the finish time!
Plenty of experiments have been done with reduced lights on times down to even 6/18! Plants will finish FASTER but as you reduce past that 10/14,,,your yield reduces at increased amounts the more you reduce lighting times....

Its not in place of hps its in addition to hps led or cmh There was a thread in the led section far red thread i cant find it this min. Continue to read about the emerson effect and far red 730 nm you are manipulating the phytochrome response in the plant changing pr and pfr so they can go to sleep faster. so you can run 14 on and 10 off I have not played with it yet but I will be in the next 2 or 3 months after I get a few other upgrades done first.

Been there, done that......NOT worth the added cost to benefit ratio! The price of the 10 or 20 watt 730nm band LED built to your cause AND the included rise in cost to run the HPS lighting another 14 hrs a week. Does NOT supply an amount of yield increase worth spending the money on the project!

I run 11/13 from the flip. Stronger and less stressy plants are one benefit not mentioned by others.

In running High sativia's. I'll start at 13/11 and drop 15 min a week till down to 12/12 and let it ride for 2 weeks, then drop 15min a week till 11/13. As the end gets closer. If I have a sativa strain, that likes to go long and not express well,,,,I'll drop it to 10/14 for the last 2 weeks and maybe a bit more if need be....

Hmm, never saw a loss from 11/13 at all.....really.

 

[bryan oconner]

10/14 is for photos not for waste of electricity pointless autos

Could of been a million factors, I'm usually improving a few things at a time. This was during a big learning period for me lol.

 

[Yodaweed]

My take is your plants get 2 less hours of light and they will yield less.

I try to do the same as you time wise. I run more crosses than straight Sativa's so they don't run long enough for me to get down to ten hours tho.

If you're referring to the 11 light and 13 dark ratio, it's not 2 hours less light, it's 1 hour less light. It's not the difference between 11 and 13, the starting point was 12 hours not 11.

thread topic says "whats ur take on reducing to 10-14 light schedule for quicker harvest" that's what i am referring to.

Peace brother!

Imma 11.5/12.5 dick too; doesnt really speed things up much tho it does help some plants finish in a timely manner; I like to pick around 11 or 12 weeks yet some still need more time. That is if you want em rock hard & ambered like I do

 

[bryan oconner]

had some of those fuckers take 16 weeks before that is stupid . and others in 6.5 weeks ! was like hold crap all done !

The plant is looking great still a bunch new pistols popping out the buds I wanna safely say I have two weeks left. I just put two more small babies in to start flowering

no this plant has a very long time left . may i suggest about updating your lighting to some thing like this . http://www.ebay.com/itm/Meizhi-Mr-300w-LED-Grow-Light-Hydroponics-Veg-Bloom-Full-Spectrum-Indoor-Plants-/231993610741?
this led should have about the same heat if not less and the yield will be a lot more ! same results as hps using these lights my self but the bigger ones . this is a major step up for you in quality and yield . and you can veg with it . trust me i tested the 1200 watt out it rocks .

What are you feeding Mr. Nymous? How much and how often? That does look N starved!

Better plan on more like 3+ weeks.......

Look bro I'm drunk I can't respond right now but if u feel something is wrogn IMA re read this shit tomorrow I been looking at lights but I can't see that much longer but I'll show pics tomorrow and we will talk thank god for auto correct or I couldn't txt

I have stopped feeding complelty BC I believe most my problem was too much nutrients. I just water from here on out. Also do u really think it need 3 more weeks my harvest date (the min time for flower 8 weeks) is December 14. Here are a few pics from today.

 

[MisterBouncyBounce]

less light and more dark = faster flowering time and less yield. period, no debate about it.

put another way, your plants will be done sooner and yield less. that is not only common sense but it is proven.

i can't even believe people have suggested less light means longer flowering time.
that would mean that a strain grown using 400 watts would take longer than if you used a 1000 watts.
which would also mean yield should be the same for both wattage only one took longer than the other.

I like the idea of vegging a plant on 24-0, then switching to flowering with 13 hours lights on, 11 off, straight from the flip. It's been an interesting read here.
