11/13 Flowering Light cycle recommended by DJ Short

curbiechris · Jan 6, 2014

I came across an DJ Short interview by Grantland.com. If you haven't read it heres the link. Its a good read.:

In the article, DJ Short recommends a 11/13 light cycle for flowering instead of 12/12. Here's what he said:

"Short said, and slowed down his voice: "For your bud cycle: 11 hours on, 13 off. OK? What will happen first and foremost is that you will see phenotypic expressions that you will never see with the 12/12."

What's your thoughts? Anyone have personal experience with growing 11/13? See any difference between 12/12 and 11/13?

only use on sat doms, pointless on anything else
but it seems to flower sats a bit faster

Makes sense, I wondered why my purp affie wasn't purpling anymore, first run was 11 /13, next runs I went 12/12. Never saw the purple in that plant again. Then I lost it, .... I must agree with dj short. Affie is indica dom as well.

@sourpuss - Were the temperatures in your enviroment different between the grows? that could have been a factor. either way thanks for your input.

i usually only go 11/13 when i grow purer sativa's they won't flower unless you go below 12/12.

OvergrowDaWorld · Jan 12, 2014

So I guess my Pure JLB wont flower at 12/12?
Its the only light schedule I can put it on. Im growing mostly ChemD hybrids.
The genetics are landrace sativa with 20+/- wks flower time. Its been on 12/12 for 2 wks.
It was recommended to me to flower @ 11/13. What will that do to my 60 other plants?

gus738 · Jan 12, 2014

what about best flower cycle for indica or indica dom ? i currently have 12/12 for flower .

stihgnobevoli · Jan 12, 2014

for indica's it just means they will finish faster.

sourpuss · Jan 13, 2014

@curbiechris the temps were always warmer except the last run. I expected the purp to return, but it didn't. Only variable I see is running the light closer to 11 13. Wasn't exact 12/12 probably more like 11 15 /12 45.

using what time ?

try 13/11 or even 14/10 the extra hour(s) of light adds a week or two of packing on weight. This would vegetate sativas.

I have been running 10.5 on 13.5 off for the past year and find most things to finish nicer under that regime.

Yup, I flower 11 on, 13 off. Broad leaf and narrow leaf.

My broad leaf cultivars express attributes show less narcotic,
more varied up effects. Flowers longer, almost 20 days longer
in some cases.

Good for me, I got time.

Weird · Jan 14, 2014

majority of the time i use 11/13

Hey its funny you should say this dropped cat, I have often read that shortening the flowering time makes for quicker flowering with less yield. The theory being that it makes the plant think that the season is coming to an end.

I was actually thinking of shortening my flower schedule for the last 3 weeks to make sure everything was finished up in time but now im not too sure.

Does anyone else have any opinions on this either way?

Yes! I was thinking about it too. Last grow i went 11/13 the whole flower period and it turned out well for me. However, this run I have completely different genetics so even if i do part-time 11/13, there is no telling if anything changed..

Anyone tried 11/13 for the second half of flower period? Appreciate any comments, fellas

bump!

genedigger · Apr 28, 2015

ive noticed slightly less on the yield on 11/13.i think its better to do it gradually during the flowering time. imo this mimics outdoors and doesnt affect the yeild as much as starting off at that light schedule.

it flowers a little faster but slightly lower yield
