10/14

anyone have experience with cutting out some more light for the last couple of weeks to 10/14, read it in spannabis i think, some breeder does it to his plants and it allows for a quicker harvest....

this is interseting...i want to try that .... but does it work.... is the question...

yes it works less yield but u can harvest in 6 weeks if you change around 4 weeks from 12 12 but if you change around 6 weeks you wont notice much of a difference maybe 4 days top

cool, yeah can't remember when he said to do it, but 6 weeks would be sweet, wanted to harvest my ppps before christmas but ran into some problems and they are still only small so might give it a go if needed. how much less do you reckon it yields?

I would just keep it 12/12 bro. Dont compramise your yield man.

i thought people only did this to increase resin production in the last week?

yeah would like to but was maybe going to go away for a bit around christmas, but i'll see how its going and whats going on nearer to the time, still interested to see how much it would actually reduce yields......

That's not true at all and that's not the reason why people do this. Switching to 14/10 your last couple of weeks promotes enhanced resin/oil build up and will also increase, not hinder your yield. This is also the time to start flushing.

think you've got it the wrong way round i'm talking 14 hours of dark to 10 light, surely that won't increase your yield?

uhm no, you don't want to do that.

have you tried? what makes you say it would be bad?

it is the exact opposite of what I know to work. so, no I haven't tried it. I haven't tried cat piss either, but I'm pretty sure it would be bad.

In theory, you are right, longer nights should create a shorter flowering period. The post about losing some yield is also true because if your plant isn't flowering for as long, it wont have quite as much bud.

I personally haven't tried it but I have heard it works...
Going with 14 hour nights for the last 4 weeks of flowering might save you a total of 4 or 5 days.

yeah it makes sense, but don't know whether to do it as 4 or 5 days isn't that much was hoping more like a week minimum but i guess it helps a bit if i'm not going to be around

14 hours of flowering is ultimately only 2 hours extra each night
Spread across 4 weeks (28 days) of flowering that is
28 x 2 = 56 hours of extra flowering.

Also keep in mind your plant is most efficient during the first 5 hours of a dark period.
The 56 hours of extra darkness only makes up for 40-50 "optimal flowering hours" and therefore only saves about 4 days (48 hours)

Overall I would not suggest this method, but I have seen it done and it does work, one of my friends grew 2 seemingly identical plants through veg and flowered them on different schedules, 12/12 and 14/10.

14/10 took about 8 weeks
12/12 took about 9 weeks

The yield is affected by the light schedule more than the time it takes to flower.
I would say he decreased his yield by about 25-30% and only decreased his total time (vegging + flowering) from 15 to 14 weeks, or around 7%

yeah i see what you mean, it's looking like i might be around so i can hopefully just let them grow out normally

anyone had any experience with growing 10/14 for the first 2 weeks of flowering then switching to 12/12 then 14/10 for the last two weeks. might be a recipe for hermies but i read it on some other forum some guy does it all the time apparently. might induce quick bud formation then give it lots of light when it really packs on the weight.....

I think that's what he meant. Night is when the resin production and bud hardening seems to happen. I switched to more dark in the last couple of weeks on my last run and it definitely made them more dense and more trichome production than the last time. It would be really cool if someone could do a control with a 2-room or 2 closet setup. Then it would be more scientific.

illt ry it once i start my grow for sure man....give me till i ge thome off of this deployment and i will do it for sur ei need to have 2 seperate rooms anyways so...if i can i will.
all sounds interesting though and i have heard of the 10 on 14 off the last week and people swear by it but most dont want to chance it ya know.
