How Do You Calculate Input and Output?
Calculating the input and output of any vermicomposting method depends on variables like climate, the quantity and type of feedstock, and the frequency and method of harvesting, producing a wide range of possible outcomes. CFTs provide a more consistent environment for vermicomposting, and thus we are able to provide our clients more accurate and predictable representations of input and output capacities. To learn more about how the assumptions behind our calculations, please see our Rates and Calculations page.

How much feedstock can a Michigan SoilWorks CFT process?
Our smallest 4×8 foot single-module CFT can process 7 cubic feet (or 1/4 of a cubic yard or 25 gallons) of organic waste feedstock per week. These numbers increase linearly with the number of 8-foot modules.
- 8 feet: 7 cubic feet
- 16 feet: 14 cubic feet
- 24 feet: 21 cubic feet
- 32 feet: 28 cubic feet
- 40 feet: 35 cubic feet
What is the output of a Michigan SoilWorks CFT?
- 8 feet: 3.5 cubic feet
- 16 feet: 7 cubic feet
- 24 feet: 10.5 cubic feet
- 32 feet: 14 cubic feet
- 40 feet: 17.5 cubic feet
Note: You will see somewhat different output numbers on our pricing table. This is to account for the difference between the screened castings and raw harvest output which includes not only the castings but also coarser, unprocessed material which can normally be recycled back into the CFT.

What are the sizes of your CFTs?
How much space do I need around a Michigan SoilWorks CFT?
I would like to build this CFT myself. Do you sell the plans?
What kind of worms should I use in my CFT?
- Eisenia fetida (Red wiggler)
- Eisenia andrei
- Lumbricus rubellus
- Eisenia hortensis; Dendrobaena veneta (European nightcrawler, ENC, Belgians, Super Reds) NOTE: European nightcrawlers burrow deeper than red wigglers and may not be the optimal choice for CFTs.
Tropical Climate Species
- Eudrilus eugeniae (African nightcrawler, ANC) Note: African nightcrawlers also burrow deeper than red wigglers and some users report that African nightcrawler castings are susceptible to falling through the CFT’s mesh prior to harvest.
- Perionyx excavatus ( Malaysian / Indian Blue)
