As a newbie myself, I was all about auto. Auto seemed so easy and the way to go as a beginner. But now half way done with my first grow, I would not recommend auto strains. Here are my reasons.
1) The 8 weeks or so that you will spend flowering, you can use the lights 12 hours a day instead of 18ish you use with autos = power bill saver
2) You can control how long you want to veg
3) Better potential yield from photoperiod strans vs autos (in most cases)
4) Ummm can't think of anything else right now but I'm sure I have more reasons
Just my 2cents as a newbie myself also
