Vermicompost is the product of composting utilizing various species of worms, usually red wigglers, white worms, and earthworms to create a heterogeneous mixture of decomposing vegetable or food waste (not to include meat, dairy, fats or oils), bedding materials, and vermicast. Vermicast, also known as worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matter by species of earthworm.
The earthworm species (or composting worms) most often used are Red Wigglers (Eisenia foetida or Eisenia andrei), though European Nightcrawlers (Eisenia hortensis) could also be used. Red wigglers are recommended by most vermiculture experts as they have some of the best appetites and breed very quickly. Users refer to European nightcrawlers by a variety of other names, including dendrobaenas, dendras, and Belgian Nightcrawlers.
Containing water-soluble nutrients, vermicompost is a nutrient-rich organic fertilizer and soil conditioner. Vermicompost tea has been shown to cause a 173.5% increase in plant growth by mass over plants grown without castings. These results were seen with only 10% addition of castings to produce these results.

It works like this: after procuring a container and setting it up (more on that in a sec), feed your worms the same organic waste you’d toss in a compost pile — which includes just about all of your food waste, save the animal leftovers — and let them have at it. They chew on it for awhile, and when they’re all done eating, they poop (hey, everybody does it) and there you go: vermicompost…
