So you decided to use a square worm-bin (meaning anything not round, could be long .... you know what I mean) for your Red Wigglers Eisenia Fetida.

The formula for calculating the surface area of your worm-bin:

Measure the width and length  of your potential worm-bin. Lets assume it is 50cm x 100cm. Multiply the measurements. (50 x 100 = 5 000)The result will be 5 000 cm2Allow approximately 500g worms per 1 000 cm2 or 1 pound for 1 square feetIn this case optimal stocking levels for Eisenia Fetida will be 2.5 kg.Your Red Wigglers can double every 3 months.Order 500g Red Wigglers and given the right conditions, you may achieve optimal stocking levels of Eisenia Fetida within 6 months.Easy steps to calculate surface area of a *round* wormbin

You got some tyres to reuse and start a worm-bin, and now you are ready to order your Red Wigglers Eisenia Fetida. I asked Kobus to make it as simple as possible so that even I can calculate it, don"t tell me divide pi by four ... (pi x dia.^2 / 4) so, here goes.

The formula for calculating the surface area of your worm-bin:

Measure the widest part of the inside of your potential worm-bin. Lets assume it is 50cm. Multiply the measurement by itself. (50 x 50 = 2 500)Multiply the result with 0.785 (pi/4) (2 500 x 0.785 = 1 962.50 cm2)Allow approximately 500g worms per 1 000 cm2 or 1 pound for 1 square feetIn this case optimal stocking levels for Eisenia Fetida will be 2 kg.Your Red Wigglers can double every 3 months.Order 500g Red Wigglers and given the right conditions, you may achieve optimal stocking levels of Eisenia Fetida within 6 months. Easy steps to calculate surface area of a *square* wormbin

Earthworm Composting: Worm composting is the decomposition by a type of earthworm called  RED WIGGLER Eisenia fetida which eats your organic raw food waste and leaves rich compost and a liquid fertiliser in return. Worm Castings Worm castings are the richest form of natural fertiliser known to man. It promotes ahigher than average growth in plants (ideal to start seedlings, when mixed withpotting mix or as a top-dressing around plants).
