Red or manure worms are kept in stock within a growing medium, and oftentimes the machines have a small reservoir in them to simulate rain and to feed the worms a nutrient solution. Electrical pulses are used to encourage the worms to come closer to the surface to obtain the nutrient solution.[citation needed] In connection with heating and constant high humidity, worms attain higher reproduction rates and faster growth.[citation needed]
