The boss is not happy about the way the side have played in front of their own fans, which is something he’s looking to change with a view to the 2015/2016 season.
“Our home form has not been acceptable or good enough. The players have been fantastic but we have let ourselves down at home,” said Gray.
“If we want to get anywhere, we have to make sure this place becomes a bit of a fortress.”
Wednesday have lost seven games at home this season, with only 16 goals scored, which is the lowest in the Championship.
That has to change for next season because the Owls have the infrastructure and support based needed to be pushing for promotion into the Premier League.
The team has to try and give the fans more to shout about at home, because a loud home crowd has the ability to intimidate the opposition, putting them on the back foot and giving themselves an advantage in key games.
Wednesday fell to defeat against Leeds United over the weekend, which was the club’s final home game of the season.
They have a chance to end on a high this weekend away at Watford, with the Hornets already promoted and it’s important the Owls try to give themselves some momentum heading into the summer.
