If you do not want to be in veg for long, you'll want to go more plants as opposed to less. 9 sounds like a good start (I've seen 12-15) if you were gonna do photos but with autos who knows what you're gonna get. I think the most I've ran was 6 and they all varied in size. So some needed elevated. Caused me more work and I'm not about that.
