Help with getting a BIG BACK

I am big workout person on building a big back , and here is a couple of things to do. Power rack deadlift where u place the support bars about an inch below your knees to take your legs out do about 3-5 sets 6-12 reps as heavy as you can then follow with some reverse grip barbell rows about 3 set with 8 -12 reps try those 2 exercises on different back day and see if your back grows.
