Less light= less growth.
If you really hate trimming, then consider non CO2, or a middle ground, Excel dosing.
Plant choice is always wise, you can mix a few fast growers with hardscape materials, or go all slower growers or a mix there as well.
I like pruning and gardening.
But you have to keep up on it and be good about whacking the stems back.
There are few methods, topping or cutting the old stem off the bottom.
Each has its merits depending on the plant species.
