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:

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