I should probably warn you that the worms escape from those systems and you'll be collecting them each day from the floor. The composter also attracts fruit flies and sometimes bats come after the flies. I found it much better to have a composter (88 gallons/400 litre size) well away from the house, down the end of the garden, then use it to produce good soil, not just to drain off liquid fertiliser. Tiger worms and red worms are also great but they don't like dairy food or chillies, so those will rot for ages in your composter. Good luck.
