| Right now, I'm really curious about vermicomposting and I'm going to do it for my science fair. I've set 6 subgoals. I'm going to compare soil texture, porosity and N-K-P before and after vermicomposting. I'm also going to compare the population, the weigh, compare nutrients between an inorganic fertilizer, observe how worms eat, and labeling all the food I gave to the worms. However, I don't know what I should do for my main goal. I have to vermicompost it for 3 months so it would be the beginning of November by then. So it's going to start to get a little bit chilly outside. Therefore I don't think I could grow anything with the soil. Thus I thought I should make several kinds of vermicompost with different kinds of worms like Eudrilus eugeniae, and Lumbricus rubellus. I already have Eisenia fetida but I can't find the other composting worms. Do you know any website that sells worms, or do you have any other main goal you can think off other than comparing worms? |

| With all the comparisons that you want to make, three months isn't very long to get results. You might consider setting up several ice cream bucket size mini-bins. You want the worms to be crowded so that they can find each other and mate. One of our Hawaiian forum members has had success with those type of mini-bins. Waikiki Worms is just one of many companies/organizations that set up workshops in schools. And then there is a woman in New York (http://www.cityworm.com/about.htm) who promotes something called Wormware, "the world's smallest kitchen composter." Folly |

| Kiyo -- Thinking more about what should be your main goal, how about comparing the results of worm composting and garden hot composting? Each time you feed your worms, place the same amount in an outdoor compost bin or pile. Your final report could be a comparison of the progress, smell, pest problems, and resulting Organic material.

| Another worm to consider would be perionyx excavatus, Indian Blue. They're reputed to be faster composters and faster breeders than EF. One idea I got from redwormcomposting.com is the '4 worm experiment'. Bentley started with 4 EFs and then counted the number after 5.5 months. I'm trying the same with PE. I'm not sure that 3 months would give you quite the spectacular results that a little longer would, but it's an idea. Since their growth can be exponential, just a little longer would make a big difference. Let us know what you decide to do and how it works out! |
