Vermicompost information^.^

• Vermicompost is the  process of composting using various worms, usually red wigglers, white worms, and earthworms to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.

•  Vermicast, also called worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matter by an earthworm.
• 
   These castings have been shown to contain decrease levels of contaminants and a higher saturation of nutrients than do organic materials before vermicomposting.
• 
  
• Worms are sensitive to variations in climate extreme temperatures and direct sunlight are not healthy for the worms.
•  The optimal temperatures for vermicomposting range from 13°C to 25°C in hot, warm areas, the bin should be placed under the sun. By vermicomposting indoors, however, one can avoid many of the problems posed by hot or cold climates. 
• Worms will eat almost anything you  put in a typical compost pile (e.g., food scraps, paper, plants,plastic).
