Hover effect on one cell of agendaWeek + fullcalendar

Hi I am using FullCalendar by Adam Shaw (http://arshaw.com/fullcalendar/). I am using a month and agendaWeek view. I want to put in an hover effect when the user is hovering over a date in month view or a timeslot in agendaWeek view. I tried to change the css as follows:

.fc-widget-content:hover {
        background-color: red;
    }

This works for month view. File attached

However, the same code selects the whole line in the agendaWeek view when I just need one timeslot to be highlighted.

Example picture below shows the whole 1:00pm slot higlighted for everyday instead of just the timeslot in Wed 02-01 where the mousecursor was.

Any ideas how to achieve this.

Many thanks.
