how big of seperate rooms to build

I'm getting my sub panel with separate circuits for my ballast and ac unit,and addition outlets for fans,air pumps and what ever, installed this week, I ordered 50' feet of panda film bought 30 8ft 2''x2'' to make my walls out I would like some input on how big of rooms to build for the best growth and happy plants any input or ideas would be great

oh come on 150 people looked and don't have a opinion that's bullshit

i would build two 4x4x7 grow tents. both with 1000w hid setup with 8 inch inlines to cool them. this will allow you to do 12 to 16 plants, a great amount to learn on.
