As I wrap up my short story about my Worm Farming adventures, I would like to share my production levels and some other hopefully helpful insight on raising Red Wigglers for casting production. Also, my plans for expansion. We have several composters and worm bins in action. For the space that I have to devote to the operation, I have found the Worm Wigwam to be the best bin for my needs. Although, I currently do not have anymore room at the location I am at to expand, I do plan on expanding in the future. As of now, I can produce approximately 25lbs of screened Red Wiggler worm castings a week.
For castings production with Red Wigglers, I am of the opinion that long narrow rows are the best approach for larger operations. I could be wrong, but it’s likely not very cost effective to have several WigWams (10 units which equals about $6k+) as a commercial operation. My opinion for large scale is go with home built setup. Only you will know what kind of space you have to work with or how big of an operation you want to have. I am considering trying to make long bins out of 275 gallon totes. It seems like one could cut those in half, cut the plastic off the bottoms, and have the worm suspended off the wire cage. You could harvest from below like the WigWam.
Another idea for large or long run worm bins may be to use pallet rack shelving. I am more partial to this idea because it less engineering AND if you decide to get out of the worm business at any time, you would still have some nice shelving for other uses. Going from the picture of the shelves to the picture of the commercial size worm bin would not would not be a big stretch in manufacturing.
However I decide to expand, I will do my best to provide video’s and blog notes on the matter.
In other expansion news, I would like to share another goal once I have these larger worm bins in place. My plan is to bring rabbits into the equation at some point. There are a some benefits to raising rabbits in addition to meat production for a worm farmer. Since the rabbit manure is considered a “cold manure” one could suspend the rabbit cages or hutches over the worms and allow the rabbit waste to directly feed the worms. This would hopefully reduce some of the direct feeding to the worms. Plus if you are you are good at handling furs, you could sell the pelts for extra income as well.
It is interesting how become busy at one project and business has led into other ideas for sustainable living and farm income generation. I am always available for any question through my Contact Us page. I would love to hear about your path with raising worms too, so feel free to share!
