A pound is a non issue with autos these days. Though like anything you have to watch your genetics as of course not every strain has the dna for mass. There are many 1 pound plus autos on just this one forum. I myself had a Mephisto Grape Crinkle go 12.47oz dry in a simple 24"x35"x60" grow cabinet with less than 300w of cheap LED's. As soon as my current plant is done I am going after the 1 pound club with another Grape Crinkle in my new set up.
Here is a couple of my last 2 Grape Crinkles.......both 71 days from sprout to chop.....
