Veg - Flowering

Hey!! - Proud to say my makeshift closet setup is working waaaaay better than expected, but I'm still working out some kinks. Basically, what I want to know is how tall (per se) should a seedling/plant be before moving into the flowering stage? I know the results will vary so a guesstimate is appreciated, thx.

i flower mine at about 8 to 12 inches about 6 nodes

i usually wait until they are about 10-12''

that is a really good height and you can get good yields too
