When setting up a worm farm vermicomposting system, how many trays should I start with?
Most of the worm farms that are sold at garden centres use a stackable tray design, and when first starting, use only a single tray. When the first tray is full, when the contents reach the fill line on the inside of the tray, then add a second tray.
It takes a while to fill a tray, as the food that’s added disappears in a few days, and the level drops back down. When the food is converted to worm castings, the level in the tray doesn’t go down anymore, and that’s when a new empty tray is stacked on top of the existing one.
