Lowe was thrilled to see Rovers pick up all three points at Ewood Park despite not playing their best football.
"Going into it we said that we need to win it," he told the club's official website.
"We know ourselves that we are loads better than that, but what we did show was a lot of character.
"They were tough conditions, we knew what Millwall were all about, it is just disappointing that we conceded two goals. We'll put that right for sure.
"The main thing is the three points, we've played a lot better than that here and drawn or lost, so I think that it could be a turning point in winning games and playing poorly.
"It can be hard to take when you've played well and lost, there were times last year where we would have lost that game.
"So credit to the lads with the character and the spirit. We did all the off-the-ball stuff very well - the dirty side of the game - and got our rewards.
"We need to be better but it is a big three points and we move on to the next one."
