Never researched the mealworm thing too much but I do raise composting redworms. It's very easy. "Farm" is made from stacked totes. The bottom one is left as is, as it's there just to catch fluids that drain off (which if done right, there isn't much of). The next bin fits inside this one with holes drilled in bottom for drainage and holes around the top for ventilation. Lay a few wet sheets of newspaper in the bottom, then add a few inches of shredded newspaper, cardboard or leaves (mine uses all of the above). Add a little sand or dirt because worms have crops just like chickees. The bedding needs to be damp but not wet, like a rung out sponge. I add veggie scraps, crushed egg shells and coffee/tea grounds about once a week and more paper/cardboard/leaves from time to time. The cool thing is, when the tote is full, I leave the lid off and stack another bin on top of it and start over. When the worms work through all the material in the full tote, they migrate through the holes into the new bin. By the time the new bin is full, the bottom bin is practically worm free and ready to be harvested. Dump out your castings and restack. The two bins just keep rotating.
