you can go anytime but its best to wait untill the plant is mature at least 3 weeks depends on how fast they grow

Best time depends on your set up and how much space you have. Also if its a super stretchy sativa plant vs a short indica.

You can flip whenever .... Many people don't give any veg at all and go straight to 12/12 from seed.

I know Del, he's a good grower but straight 12/12 from seed is not a good idea. Plants don't flower anyways for usually about a month, so why deprive them of daylight during that time and thereby limit your end yields?. The only time I do it is with a certain skunk strain that stretches to the heavens with any amount of veg whatsoever.

I do 12/12 from clones ... I'm very happy.

I like 4 weeks, but I also top. I generally top around 2 weeks and give it 2 weeks to recover and start growing really good again.
When it looks to be thriving I flip to 12/12.

There are some strains that do well regardless, that skunk I mentioned earlier would be done 12/12 from clone as well. On the flipside, the blueberry I tried from seed on a 12/12 was an absolute disaster. It started flowering at about a 3" height, so I wound-up re-vegging outdoors. That's another problem w/straight 12/12, it isn't for novice growers b/c some strains hate it and you have figure out what works.

I'm a little dubious of 12/12 from seeds too.

I suspect I would end up with a 3 incher too. (obvious joke avoided) ... but I can't deny the results Ive seed online. ... For me 12/12 from clone works really well, as long as the clones have a healthy root system.
