Composting worms will thrive just about anywhere with sufficient food, water, air, and plenty of cellulose bedding (coconut coir, wood shavings, shredded cardboard, etc.) for substrate.

Worm bins of various designs make it easy for people to manage their worm colonies.  A worm bin is any container with good drainage and aeration. They all work, but everyone has their preferences.  There are simple box bins you can make yourself, stacking tray models, continuous flow systems, etc.  Go to Google and YouTube to find a worm system that appeals to you and meets your needs. Follow the instructions they provide.

Photo: Worms came to Ka’ohao Public Charter School (then called Lanikai Elementary in 2014 and made a huge impact, instigating Lanikai’s Zero Waste Revolution. Ka’ohao School boasts the largest vermicomposting operation in the state, processing over five tons of kitchen and cafeteria waste annually.

  We neither sell nor consult on home worm systems although we’ll recommend our favorite, which is the Worm Inn, re-named by us The Worm HangOut.
