I Need a mass building back routine!

[BHT]

Hey all, Im looking for an effective workout to gain mass on back,
this is usual routine
Seated rows-- 4x10
Lateral pulldowns---- 4x10
Bent over rows with dumb bells 4x10

I usually increase weight in every set going from pretty light for a warm up set and then 3 work sets

Any help is greatly appreciated!
