Rowing for ectomorph

hallo from Italy,

 i am a typical ectomorph tall 1.90cm x 80kg (6'2"x175lbs), my shoulders are
small,  poor chest and skinny legs,

 I am 28, do you think rowing can help me to put muscle and mass??? Someone
says "Rowing no because it's aerobic, just bodybuilding to add mass" but i
see every rower is enormous!!

 How can I row in my house,do you think Concept II is good for me?

 Thank you
bye
