Some of my most popular videos are balcony composting videos…I made them a long time ago using really small buckets.
While this method does work, you’ll get better results with a bigger bin.
Every time I respond to a comment on those videos, I always mention using a trash can.
While both a cat litter bucket and a trash can are considered “cold” composting, I’ve found that the more volume, the better. It allows for more material, it’ll insulate itself a bit better, and you need volume in order to get the process really going.
Watch the video above and apply that design to your balcony/confined space if at all possible- your results will be much, much better!
