The General rule I like is to do AS LITTLE AS POSSIBLE while gaining as much muscular weight and as little fat as possible. This will be different for every person really... Some people can stay lean with no cardio, some people get fat... You will have to find out where you are in that spectrum
Diet also plays a huge role. Moreso than cardio. A shitty diet = shitty results. Now, if you are eating well and still putting on fat, at that point you have to either cut back a tad on calories, or (in my opinion the better option) add in 1-4 cardio sessions a week.
This will probably be a constant game of figuring things out, and you will make many mistakes along the way... Not enough food, too much food, too much cardio, not enough cardio, etc...
There is a reason why people who have been doing this 10 years are so good at it, they have made all of these mistakes for themselves, figured out their bodies, and are now chugging along on their customized system and reaping the benefits of their hard work.
Other things will also play a factor, like how active you are outside the gym, what kind of job you have, your metabolism, etc... All of these things make it impossible for anyone to give you a blanket statement about cardio during YOUR bulk.
