It's all prerogative my friend...Count on your plant stretching to roughly twice the size in the first 3-4 weeks after the flip ...we only do small plants inside, i flower plants smaller than yours most times...if i flip a 6" a clone that has vegged for 2 weeks (after rooting) I can count on roughly a 1-1.5ft plant once finished which will yield roughly 1 -1.5oz...if you veg out a 4-5ft plant count on it filling your grow space once in flower...it's entirely up to you..here's a pic of one of our small clones in a 2gal container that has received roughly a 2 week veg before being put into flower: https://tinyurl.com/y9rw2yop ... hope this helps :)
