Add the sand and peat moss

Now place about 1.5 inches of sand in the bottom of the bucket. The worms will not cross this barrier . Top that with the peat moss, leaving about 6 inches open at the top of the bucket. (Your worms will arrive in peat moss and once added should have about 3-4 inches of space before the lid.) Spray the peat moss with your kitchen or bath sprayer so that it isn't dirt dry. Leave your drainage bucket below for this step and lift the worm bin (top bucket) occasionally to check for run-off. Once water is dripping from the bottom, the bin should be adequately wet. The peat moss shouldn't be sopping wet, but should feel quite moist in your hand when you squeeze a fist full of it.
