Heavy Weights or Light Weight for bigger muscles?

Heavy weights are preferable for increasing muscular size. More muscle growth hormones are released when you lift heavy weight for a short period of time, which aids in rapid muscle growth. Additionally, it burns more calories than light weight lifting.
Lifting a large amount of weight requires a brief workout duration. Lifting lighter weights for extended periods of time would therefore be considered light weight lifting.
