How to SOG with veg and flowering tent

i have a couple of questions concerning SOG

i will be veging clones with the mother then move them into a flowering tent.

my flower tent is 1.2x1.2m
The pots will be 20x20cm
how long should i Veg the clones?
how many clones should i put in my flowering tent?
what about the SOG net?
is it enough to put it in the flowering tent and start the bending there in the first weeks of flowering.
im imagining if i start with the net already in the veg tent it might get complicated, to get them out of the net…

im not sure about the best way of action for this particular scenario.

any help or input will be apreciated.
