He told BBC Berkshire: "These results have a greater impact on where you finish regarding the play-offs or automatic promotion.
"Morale's really high at the moment, confidence is high so hopefully we can nick a few wins."
Reading have lost just one of their last 12 fixtures in all competitions and Griffin says there is great self-belief amongst the squad ahead of the Tigers clash.
"If you can go away to the likes of Doncaster, Derby, Hull, pick up points and put in a good performance that's obviously going to install a certain amount of confidence and self belief," he said.
"Hopefully we can keep performing well, it's a home game and the frame of mind that we're in, we're looking forward to the game and think we can win it."
