I went Hog-Wild about wicking seedling trays in this article:

But bear in mind that I'm a total nut-job about soil aeration and drainage. Most people seem able to start seedlings indoors without wicking gadgets and super-coarse seedling mix. They just (somehow) avoid over-watering.
After killing most of
many trays of seedlings indoors by over-watering, during my first three years of indoor seed-starting, I've learned to jump through several hoops until I master the art of NOT over-watering.
