Services cards layout using CSS Grid

When switching to desktop layout, and after setting css grid, the red and orange cards that are together in the central column, had a smaller height than the other two on the sides.

Min or max height on these cards had no effect, they kept staying shorter. What worked was setting the grid row height to the given height, as well as setting the cards' height explicitly, which is what i sticked with.

Is that a correct/good approach? Was there another way of making the cards' height go up to 250px without explicitly setting to this number?
