Worm Bin Calculator

Disclaimer: this tool uses the average stats of worms in order to make the calculation. The resulting numbers cannot be accurate due to a lot of possible criterias potentially affecting the results; things such as weather conditions, breathability of the material of your worm bin, the type of food you give your worms, how frequently your worm gets disturbed by over-worried worm farmers :-D etc...

The purpose of the worm bin calculator is to help the beginners to get their numbers and know how to start:

  • How much worms do I need?
  • What size and how many bins are required?
  • With what I currently have, what is the average time till full speed?
  • etc...
