I use egg shells in the GH bed and in pots outdoors, I'm convinced it works and even if it doesn't it gives me a sense of satisfaction and if nothing else the calcium is good for the plants .
I also start using a garlic spray around hostas early in March and use a home made seaweed spray from mid summer. Mulch pots with washed up seaweed too. It has a little sea salt in it which slugs don't like and if all else fails rely on a sprinkling of blue pellets.
The GH bed is also mulched with seaweed a couple of time during the growing season and there's never been slugs in there.
