Worm's Have Arrived! Picture Added

[Mackay]

I just ordered my worms yesterday and they should be arriving tomorrow. I am preparing their boxes right now and I am about to put 4 wood posts in the bottom two bins to lift one out of the other. I have 3, 18 gallon rubbermades. How high should each bin be lifted out of the other? I am thinking 6 inches but don't really know.

anyone know?

Never mind. Just found my answer on another thread, its 6 inches.
