First indoor grow.. Can't choose the best strain!

I read a lot about cannabis growing but now I'm stuck.. I can't choose between a lot of good beginner strains like:

northern lights
big bud
norther lights x big bud
skunk #1
white widow

What should I buy? I need indica plants expecially because they are small, they flower fast and yield a lot

My white widows were excellent smoke and very easy to grow. they only got to be about 3 feet tall but yielded roughly 2-4 oz each and that was my first grow. Highly recommend. If you do choose that strain don't be surprised if they are really small for the first 3 weeks as this is normal for the strand and they will typically grow at a much faster rate after the first month

Northern lights x big bud is supposedly a legendary yielder. I'm interested in trying this strain myself.
