Vermicomposting, worm bin, composting with worms community and forums
Here is a link Lawrence Taylor(Bok)provided.
I did something along these lines a good while back,and called it the Hantsel and Gretel effect.If you wanted to know where the highest concentrations of worms were,you used oatmeal.You could also add some food,and watch them clear a path through the oatmeal to the food.A bit harder once you get large concentrations of worms.So what i did was get someone to design me a maze.Haven't built it yet.But this one is made of fiberglass with several end result chambers.Still have to locate a red piece of Lexan to filter the light so it doesn't affect the worms.The Lexan bolts down where there is no other route for the worms to use except the maze.Are worms of a certain specie smarter than other worms? I'm thinking PE would simply cross over eventually if they could.
Would worms over a period of time,decide to take a route to a certain food?Or go to all of them?These are just some of the tests you can do with something like that.Think outside the box!
