How often and how long should I go to the Gym to bulk up?

RyanEC
I recently finished cutting fat and now want to focus on gaining muscle starting on New Years.

Previously I would spend 3 hours at the gym 2 to 3 times a week doing mostly cardio with a little resistance training to maintain muscle.

As I understand it is best to go to the gym almost every day of the week but now only spend a half hour or so there?

Is that the best way?
