how much longer before 12/12

Flow NL5 C99

Hello all,
I bought these as clones 3 weeks ago and planted them in Fox farms organtic soil. I am using a 1000 watt HPS light. The NL% is 15 inches tall and the other 2 are about 12. How tall does everyone switch over to 12/12? This is my second grow. with my first I grew 1 big buddah and we let her get to 4 feet before switching over and only got just under 50Grams.

soil plants 20 to 25in unless you have a a issue with height

I was wonder cause I have seen people on her that kick them over really early but they must be using hydro.

yah hydro grow faster, at least ive noticed that

i put mine 12/12 when they r about a foot or so,everybody has theyre own preferance,a foot works best for my set up-3000w perpetual,

2ft tall mon

Do you grow in soil?
