This feeder holds about 2L of syrup and goes inside your hive over a crown board so its perfect for flow hives. It is 26 cm in diameter and 7.5 cm tall.
As its inside your hive so there can be no problem with ants or robber bees stealing the syrup. It's a ladder style feeder so the bees climb down a ladder to the syrup and are less likely to drown. for a video of this in use click here https://www.youtube.com/
