Subpod is fine to use for 1 person and under 15 kilograms per week. You will start with about 2,000 worms and they will gradually build in numbers based on their environment. If you don't feed them much, they will eat what they have, and not make more babies. You may also consider scrap sharing with neighbors, friends and family. Ask them to donate food scraps to you Subpod. This stops waste from going to the landfill (creating methane gas), and creates more compost for you and your garden!
