No. If this were true we could all take 5 lb dumbells and bench press it very slowly all day and grow. You need to cause the muscle to work harder everytime you go to the gym through progression. Your muscle progresses in work performed and it grows accordingly, provided the calories are ideal.[/QUOTE]
Oviously the intensitys have to be high enough as well, but why do you think heavy slow eccentrics work for muscle size?
