Constructing a home-made bin
We explain and illustrate the most simple and least expensive way to construct a home vermi-composting system.
Begin with a 9 gallon Rubbermaid Roughneck tub - as illustrated in the first photo (below). Because you will need to drill holes in it for air, you might want to avoid the harder, almost transparent planstic storage tubs which have a tendency to crack when the holes are being drilled. Drill 3/8" holes on a 3-4 inch grid on the top, the bottom, and all four sides. (The worms will not leave the bin because they are photophobic--they avoid light. They also want to stay where it is dark, damp and a food source.)
Fill the bin about 1/3 to 1/2 full of shredded, saturated with water newspaper as illustrated in photo 2. Avoid all the shiny sections, the "blow ins" that might be included with the newspaper. The colored newsprint is fine since the colors are soy-based. Plunge the shredded paper into a bucket of water until is is saturated and then squeeze it lightly and put it, still dripping, into the bin.
Then, place your redworms and a portion of the food material and castings that was in their prior bin on top of the wet newspaper. Add the food for them and finish filling the bin with wet, shredded newspaper. Put the lid on the bin and you are done. The worms are ready to go to work.
