Ditto. I have the same question. My worms will soon be overflowing their winter bin. I would like to use them for vermicomposting humanure, and then when we have too many for that use them on a larger composting scale to sell high quality potting soil . . . If you watch Olomana Gardens videos on YouTube or purchase his aquaponics video, he has excellent information there on worms. http://www.olomanagardens.com/
Five years ago, I had a Worm Bed. I was living in a little town. I would go to the corner where the Boats would drive by and put up a sign. I bought foam cups and lids. I sold them for 3.00 per dozen that summer. ( I was an adult then, Not a kid) But now I want to get into it again, when I relocate. Trying to get other peoples Ideas. It would be great to product enough to sell 25 dozen a weekend and keep that bed going all of the warm season.
The problem is when I sold them I kind of destroyed my worm adult supply just to sell them. Maybe I need several beds and rotate back and forth?
As mentioned, Olomana Gardens sells composting worms, vermicast, vermicast with eggs and worms, and large burrowing worms. His farm produces worms and vermicast everywhere on the farm. in his grow beds, under his chicken coupes, and in bins. He has an abundance of worms from years and years of raising them. I visited his farm and i saw at least a dozen 50 gallon totes filled to the brim with pure vermicast. He also sells numerous things grown on his farm.
Another lady in Honolulu has a workshop to set up a worm compost bin she also sells the worms and vermicast. At the time it was $30 you get 1 ounce of worms and a small plastic pot to put your worms in to start you compost bin. She teaches you how to care for, raise, and harvest worms and castings.
So yes it is possible to make an income, yet it looks like some time may be needed to build up a supply of worms without wiping out the population selling them all.
Last week a previously un-introduced neighbour approached me for a donation of worms and castings. It seems I am getting a reputation for sharing my little babies to good homes. I raise native earthworms that have travelled with me from house to house using the green pre-food choppings of a Thai restaurant. The neighbour told me that the cost is generally 37.00/ lb.
I think i am in the wrong business, at least in the summer when they are most plentiful.
