Extended light during bloom....

Has anyone experimented with the extended light theory mentioned in the growfaq? Got a little one I am interested in trying it with. Was thinking switching at week 3.5 to 21:36/12 for 2 weeks then back to 12/12.

anyone had luck with this????

my friend has 13hrs on/ 11hrs off - no results yet, but everything is going as it should be.

I am talking about a cycle of 21hr26min on/ 12 off.....Check the grow faq under advanced/ increasing yield.

I hope your friend has great success!!!!

They say to only use the 21:36/12 during peak bloom, so I am gonna try. It's only one plant going nuts in a cfl/led box....would be a shame to lose it tho!

We'll see!

I tried the 21:36/12 cycle "on planet ito"... It was easy to setup on the digital timer. It really keeps on truckin in flower mode!

for bloom 12/12 will do fine for me.
My rule is keep it simple.
already out of the norm wth the LEDs....so why not....I have 8 bushy monsters in my big cab, and a few large sacks to go thru. My bong runneth over!

This will be an experiment of love, and hopefully not a lesson in pain!



wish me luck!

That's what I was looking for thanx!!!!

i'm thinking weeks 3.5 to 5.5.....how long did you run it?
Maybe 45 days - and it was fine. But there was a confound because they dried up and almost died... until I installed a negative ion generator... but that's another story...

I would supplement CO2 if you're gonna use this 21:36 light schedule, which I believe was written in that ito post we saw (in addition to making sure temps don't get too high).

Good luck! And, FYI, I read that when using LEDs you should go NO DARK period AT ALL. This will obviously give more time for the plants to make energy...

hadn't seen that....do you mean during bloom or veg?
the box is in garage with a massive nat gas heater so I think they get plenty of co2, but I need to pick up a bloom booster to sup all that liight....

hmm I dont remember, but it would make sense if they were just talking about veg since bloom needs the darkness to get her into bloom mode...

hey, this is ridiculously late seeing as it's a response to the third post BUT I thought i'd chime in since I'm reading it again. 13/11 will increase your yield. Generally adding light during flowering will add time and mass to your harvest.I assume it won't add bud as much as running 12:26/12 but it's a simple way of increasing yield.

Thanks. Best of luck :blsmoke:

Nice Led Lab Master Will.

Oh and I think I should clarify that you can run the LEDS in BLOOM 24/7.

There is no need to ever put LED ONLY plants into Darkness...

(Ok, ok before I come off as one of those people who just post bullshit and think no one will ever call them on it, that is straight off my memory, and I do have the "proof" in front of me, honestly just what I have read a couple dozen reputable and researchable places..)

Check it out...
