12/12.... and back 24/7

54 posts in this topic

I decided to switch my light schedule at 12/12 because my white Widow at 50 days...( 7 weeks and half ) won't bloom ...

I've read different forum, but is still not clear if ; Once she'll  start to flower can I switch back to 20/4 ?large.0_20171031_101138.jpg

Or should I keep 12/12 till the harvest ?

And also ....

Does this light schedule effect negatively the small plant just born ?

Hi @Sal81

 

A plant will continue to veg indefinitely if left on 18/6 or 20/4, so no chance of flowering with those settings - the plant responds to changing amounts of light, so the plant thrives and grows in the long days of sunshine and as the year ends the days shorten and the plant flowers for reproduction. That's what your time schedules do, they emulate seasonal changes and can be used to control various stages of growth.

 

Once you switch to 12/12, you stick to that until your done - messing with light schedules is not best advised; inconsistent lighting can cause your plant to stress and stressed plants can turn hermi - so stick with 12/12 once you turn them... After you have harvested your plant though, you can return it to veg (you'll find info on how exactly to do that on the boards) and regrow it if you choose to.

 

If you have seedlings or very small plants in there on a 12/12 light schedule they will begin to flower as soon as they get a chance and that means you'll only ever have a small plant and small yield from 12/12 from seed... It'll grow and flower though!

 

Cheers! :yep:

In theory it doesn't matter with autos, but yours sounds like a stubborn one, could be a semi-auto. If it needs more than 4 hours dark to make it bloom then I think it will need that same amount of darkness to maintain it. You could try 18/6 or 16/8, but if the rest of your plants are ok with 20/4, then you could just take that plant out every day and put it somewhere dark so it gets 12/12, but that might be too much of a pain for you.

Well these are my first autos and one of me Sin Tra Bajo only started flowering yesterday at 53 days old. Can't see  being finished in the 8-10 weeks it says on the packet if it's taken 7 1/2 weeks to start!

Give it a few more days to see what happens...

Have you got any plants ready to go in for grow 3? If not, why not leave it with the other plants under 20/4 then flip it 12/12? It should fill your 2'x2' tent easily on it's own Under a net and the current plants will yield more. :)

Hi mate, I see your reply only now ...

My tent is 80x80 ..160 cm 

I think you made mistake ...

Wherever I've got 3 auto's " wappa" 

From paradise seeds ...

I read around that they are really fast and strong smoke too, plus does it's job and is easier to grow for beginners ...they germinated 3/4 days ago ..

I'm so happy ... looking forward to see how they will be ... 

As I'm with White Widow too!!!!! 

I really hope this time I will not mess around with something again ...

 This is my first time with auto's, although I've done loads of photos in the past. If it were me I'd only feed it grow feed until it shows signs of flowering. I'd keep it in with the other plants and let it keep veggin' until you chop the others then put it 12/12 if it hasn't started flowering by then.
