How to Compost With the BiOrb
Use homemade organic compost to nourish your plants and vegetables. (Flower garden image by MAXFX from

Starting a vegetable or flower garden requires the right outdoor site, the right plants and a good combination of soil and compost. Organic compost is available commercially, through garden shops and nurseries, but is also easy -- and less expensive -- to make at home. Build an efficient "green" system using an old BiOrb fish tank and kitchen scraps.

Skill level:

Things you need

  • BiOrb tank
  • Wooden spoon or shovel
  • Lid or plywood

  1. 1

    Put your BiOrb in a protected area where it won't disturb anyone. Composting incorporates decomposition and may smell unpleasant in tight spaces. Choose a site away from the house that gets plenty of circulation and warmth and is away from any wooden structures. If your area gets a lot of rain, find a spot where the compost bin is protected from rainfall.

  2. 2

    Fill your BiOrb 3/4 full with kitchen and yard scraps. Use leaves, grass cuttings, spent blooms and foliage, and anything vegetable-based from the kitchen. Avoid using meat products as they'll draw animals. Include egg shells, nut shells, coffee grounds and grains. Good compost consists of a large variety of ingredients.

  3. 3

    Pour water into the BiOrb to moisten the compost. The water helps the bacteria in the compost break down the matter, so the pile should always be moist, but never wet or soupy. Add water once a week or whenever you notice the compost drying out. Your scraps won't break down into compost if they become dry.

  4. 4

    Turn the pile once a day to get air to the bacteria inside. The scraps won't break down to become compost unless they get adequate air circulation. As the compost breaks down, it should get warm. Monitor your BiOrb compost pile; if it's staying cool or getting wet from rain, put a lid or piece of plywood over it to increase the temperature.

  5. 5

    Add scraps to the compost as the pile shrinks, and continue turning and watering. Use compost when it achieves a consistent look and feel of soil.

Tips and warnings

  • Add red worms to the compost pile to break it down faster and to add an additional boost of nutrition.
