I feel good feeding the worms paper towels I bring home from public restrooms. When changin Do follow the instructions for emptying the trays. I left mine with the worms a little long. Also, the worm tea collects quickly in warm weather. So I raised the worm hut a little and put a bowl under the open spigot.
