I majored them at first day of flowering to see how much they will stretch. I just forgot to add here.
6+ 13.7" (35cm), 7 9.5" (24cm), 9+ 16.5" (42cm), 14 6" (16cm) and 8 7" (18cm).

Its a bit hard to put them in a proper line by these sizes. I am planning put the pots like stairs with reflector covers by sides. They are more or less like that by now without reflector. Job will be done this week with the final light setup i hope.
