When to change to 12/12? what works for you

[mattao21]

Hi all,

As the title suggests, what the best time you've found to change over to 12/12? so far im 21 days in, getting 7 leafers coming through.

i want to keep this one nice and short and so far it's working well with the light being an inch above the plant (cfl).

cheers all

I do it when the plant get to be about 1/3 my height restrictions, which is about 12 inches.

I have a little over 5 ft of headroom, so I flip when they're about 12-15 inches tall. I usually have pre-flowers showing pretty good and at least 10 nodes by the time I'm ready to flip (probably around 6 weeks on the last one).
