Should I use perlite in my vegetable garden?

Perlite has its place in soil, but it is extremely useful in hydroponic gardening as well. One of the most popular ways to use it in hydroponics is in propagating plants by cuttings. However, it can be problematic in higher-water settings, such as ebb-and-flow systems or deep water culture.
