Why Pure Black Castings™?
There are a lot of worm castings on the market. Some are "certified organic" some are grown organically but aren't certified. Some are more worm castings than vermicompost, some are more vermicompost than worm castings.
Know your worm castings
When choosing a worm castings product as your fertilizer, it's important to know where a particular product falls in the above classifications. The cost should reflect the quality of the worm castings you are purchasing and using in your gardening or farming.
Think of vermicompost more as a soil enhancement, adding tilth to your planting medium rather than as a fertilizer, although it does contain microbes and has fertilizer value. Vermicompost should be relatively inexpensive and probably should be bought locally, since the shipping costs can be prohibitive (especially if it's wet).
Worm castings with residual vermicompost material
Again, the shipping of un-concentrated worm castings that also contains large amounts of vermicompost is not cost effective. Before purchasing an unknown source of worm castings, it's probably wise to get a small amount or sample before getting large amounts only to find it isn't straight castings.
