Quote Grow with white is very tough. Enforcers, Dryads, Mages, and StPs along with siided in artifact hate can hurt big time.
Back when DuckTape was being tuned I remember playing against it with Gro. It was a terrible matchup for the Gro player, just because of the small number of permanents Gro puts on the board. Losing even one land to a Tangle Wire or a Smokestack really put a crimp in your game and the Mis-D's were useless.
Looking at your short description of the games I'd suspect you were more unlucky than outmatched?
