asa hat copyHello, worm farmer and welcome to the Worm Shi*fter web page. My name is Harry Hopkins and I invented the Brockwood Worm Shi*fter, the first reciprocating three stage worm harvester. The Worm Shi*fter separates worms, castings, and cocoons in one 20 second pass for a 3.5-gallon container.  I also invented the Brockwood Stall Shi*fter for the equine industry. The Stall Shi*fter is for cleaning horse stalls where it separates horse manure from saw chip bedding. Both machines are identical except for the screen.

One day I got a call from a worm farmer who questioned me about the Stall Shi*fter. During our discussion, he explained that he was in the vermiculture business and raised African Night Crawlers. He was using a large mechanical machine that was cumbersome, loud and frequently malfunctioned. We put our heads together and designed a new screen for the Stall Shi*fter that would sift worms, castings, and cocoons in a single pass.

bloomingfoods1I have been developing, improving and selling my Stall Shi*fter since 1997 so it is well tested in the field. I have customers who use them 4 hours per day, 365 days per year since then. The very first production machine sold is still in use today. I am not a worm farmer and what I know about worm farming I learned from my worm farmer customers. I am more of a gearhead problem solver interested in making tasks easier with new tools.

Thanks for your Time


Worm Farming can be a fun and profitable business


Are you thinking about starting your own Vermiculture business? The vermiculture industry is also known as vermicomposting, worm farming, worm grower, commercial worm farming  commercial worm farm system, etc. No matter what you call it, the bottom line is, you will be raising earthworms as a business. There are a few questions you need to ask and answer before you venture into the vermiculture business.



worm groupThe main two types of earthworms used in commercial worm farming operations, they are Red Worms and Night Crawlers. Red worms are pretty standard in the industry for small backyard operations or for do-it-yourself homeowners looking to do some worm farming or to raise some earthworms for fishing. Night Crawlers are the earthworm of choice for many commercial worm farms. But there are many species of Night Crawlers, so make sure you do your own research for the ones that work best for you.


African Night Crawlers, Eudrillus Eugeniae, can grow 6″ to 8″ long. My worm farmer friend tells me that in his average 3.5 gallon bucket there are 300 Night Crawlers. According to his actual weight tests these African Night Crawlers grow up to 8″ long and there are about 150 of them to the pound on average. He also tells me these Africans are by far the most voracious of all worms and can produce more castings quicker than any other worm in the environment he provides. I’ve spoken to others who make the same claim about Red Wigglers.

The  Brockwood Worm Sifter takes 30 seconds to harvest a bucket of worms, castings and cocoons which yields 300 worms, 9 pounds of castings and undetermined cocoons depending on the bucket. This works out to 240 pounds of worms and about 1000 pounds of castings per hour at the rate of 120 buckets/hour.

Here is another opinion taken off of the internet about European Nightcrawlers.

7 Reasons to LOVE European Nightcrawlers
Saturday, January 10th, 2009

Have you tried European Night Crawlers? If not, you are missing a treat!
1) Euro’s are very good Composting Worms! Excellent for recycling your scraps.
2) Euro’s large size makes harvesting a breeze!
3) Euro’s have a nice thick skin. They are a VERY durable worm.
4) Euro’s are VERY prolific. Everytime I look in the bedding, I find hundreds of cocoons.
5) Euro’s are great fishing worms. Just the right size for a large Catfish, Trout, or Bass.
6) Euro’s can be mixed in with other composting worms.
7) Euro’s are easy to get as big and fat as your little finger.

What type of system am I going to grow them in?

Smaller growers will use worm bins or worm beds for raising smaller quantities for their own use. Larger commercial worm farming operations will use big “worm bed systems” or some type of automated production growing system like the UNCO System used in the video on our home page.

How am I going to harvest the different products for sale?

The Brockwood Worm Shi*fter

This is the most interesting question and the most critical decision you will make in regards to the success of your  worm farming business. Normally there are three saleable items, castings, cocoons (eggs). and worms. Separating and collecting these items can be time consuming and back breaking work. This is where the Worm Shi*fter can save you time, money, and the backache.

How will I market the different products produced from my commercial worm farming operation?

worm on hookWorms are sold into the fishing industry and the composting industry. Worm cocoons are sold into composting industry and the garden industry. The worm castings are sold into the garden industry and the organic fertilizer industry. You must establish a good market for your products to have a successful worm farming business. In states where it is legal to grow medical Marijuana, worm castings are an excellent resource for the growers.

I would like to pass along some advice from my Worm Shi*fter customers to help you make better decisions when starting into the vermiculture business. Start small, you can always grow your business as you become more familiar with the business and markets. Start by doing most things by hand. When you get your feeding and breeding system established invest in automated equipment like the Worm Shi*fter so you can grow your business.
