good strain to buy?

I'm lookin for a high yielding potent indica strain any recommendations

northern lights# peace.

What about Big Bud? I don't know if it's as potent as you'd like but it's supposed to give a big yield.

i wouldn't mind growing big bud but how big do the plants usually get by harvest time indoors say if i had it on 12/12 from seed to harvest

im kinda lookin for something that will stay short like around 2-3 feet max

and something kind of exotic
