In the middle of this thread, trying to gain understanding. Going to 12/12 in flower tent that was 10 1/2/13 1/2 for years and am filling with planted sprouted beans. 4 LED Boards in 2 1/2 x 5 tent running 380 watts at the moment. Can do 500 watts with same Boards.
I’ll be reading here a while…….?be back.

This thread inspired me back in 2014. It's handy for a lot of reasons!
It's seems obvious to me now that they don't need extended light hours for vegging but previously I did assume they'd need some sort of veg period, then a while back the subject come up and when equatorial countries were mentioned the penny dropped as they have roughly even hours of day/night.

I prefer short vegging periods 4-5 weeks usually but for finding a good pheno I think straight to 12-12 would give me the same result less the cost, time and effort of vegging 1st.

Weight wouldn't be important but I'm still curious about the yeilds starting from 12-12?
just a ball park figure.

I had a lot of fun running a 1212 from seed tent a few year ago (only 2x3 in size and alongside my 4x8). Started in solo cups but preferred 1ltr square pots so I could cram them in (about 40 plants before sexing). It became obvious that some strains really took to 1212 and put out and some seemed to struggle to get going.

Yield was strain dependent, some would put out an Oz in 1ltr pot or just under, others over half and some you'd only just make double figures. It was worth the time and electric though.

One thing to consider if you're pheno hunting is how you keep the plant around. You can top (think @Opie1971 may have done this and flowered in larger pots? Hope your well if you read this mate) or reveg at the end of flower (leave lower buds, pot up if you can, 24 hour light for a week then 18/6, shoots will appear within a couple of weeks out the bud).

Post up if you go down this route, its something I'm thinking of doing again later on in the year.

Thanks a lot buddy that's some good information for me to take in.
I'm hoping I find a good pheno from what I've got atm failing that I'll be starting some future seeds at 12-12.

If I do find a good pheno I've some seeds in the fridge I can play with when I'm flowering said good pheno :-)

@numberfour I've only re vegged two flowered plants before both looked like they could've died is that normal or is it possible they can die trying to re veg them?

Cheers!
I did lose a couple of re vegging plants at the start to over watering, I'm wondering if that's what happened to yours, that was the only problem I really had (along with the odd plant that wouldn't re veg, it happens). I found the plans visibly did nothing for about two weeks then you'd see a shoot come out of one of the buds.

Were you able to pot up ? I've read some people who are unable to pot up use grow nutes straight away.

No I wasn't able to re pot them in fact the pots are a bit of a pain being a bit big.
Air layering is another option for clones later in flower I've at week 7-8 iirc.

Eta... If I plan for reveging I'd leave room to put them in a bigger pot.

I've only ever used the potting up method (lol easy from 1ltr) but was chatting to a lad last night who flowered in larger pots trimmed his roots and put fresh soil in his pot and had success. I think it's finding what works best for you / space.

"What Does 12/12 Lighting Mean?
The 12/12 light cycle means 12 hours of light and 12 hours of dark. The normal light cycle is 18/6 for plants. Using the 12/12 light cycle stresses the plants and has a few desirable effects for the grower. One is that it can force flowering and make the plants sex female. The 12/12 light cycle is done in a grow room.

Maximum Yield Explains 12/12 Lighting
The 12/12 lighting technique makes the grow period last 7-9 weeks. This method eliminates the vegetation stage of growth. It can help some growers conserve in space and time. Using a 12/12 lighting technique from the start means that plants will start to produce flowers as soon as they start growing. The lighting pattern is similar to that of the end of the growing season and it tricks the plants into thinking they need to start flowering."

What about 12/12 at a week to 2 weeks from planting sprouted beans?
Any amount of vegging wouldnt hurt anything. I like hydroreds 12/12 from clone routine.

That's not true a seed straight to 12-12 still has a veg period.
observe what I put in italics - all madeup BS

what kind of an outlet is Maximum Yield actually? this is the fourth article I read from them and each had gross mistakes in them

They give me that rag for free at the hydro store. It's the most corporate looking garbage. I've got like 4 issues in my cars trunk and I keep forgetting to throw them out lol.

There's so many benefits/negatives to 12/12 from seed that it would make a great article if done properly. There's comparison to auto flowers, optimal container sizes, yield cost analysis vs. traditional flowering, cost per gram analysis, equipment live expectancy etc.etc.etc. they put out that? That's horribly inaccurate.

They could take an hour in this thread and come up with a better article with more accurate information instead they just make shit up. No one vets it. 0 Editorial work...
