INDOOR VERMICOMPOSTING BINS, PLANNING AND PREPARATION
Red composting worms are what’s known as leaf letter worms. Unlike Earth worms or Nightcrawlers who live in the first few layers of soil, composting worms live in the layer of decomposing organic material under the leaf litter and above the soil line. Here they happily move along eating the decomposing leaf litter and producing Vermicast.
Red Wigglers are not indigenous to Northern climes though they can tolerate fairly radical temperature swings they prefer the 25-30 Celsius range like found in a more temperate climate.
It’s helpful to keep this in mind when planning an indoor Vermicomposting bin, their natural habitat is quite shallow if compared to Nightcrawlers for example who can reside up to 18 inches under the surface. When employing the use of bedding in a bin, mimicking this natural leaf litter by keeping it 2-3 inches deep, moist and warm will benefit your colony. Red worms need air so ventilation is a must, you want to create aerobic composting and deter anaerobic decomposition. In fact too much anaerobic bacteria will kill the colony. Just as in Aquarium culture a healthy ph balance and a high beneficial bacterium count are what keep your bin going strong.
