Before we get started, let’s look at what factors you should consider when buying a worm composter bin. Making an informed decision now will mean you’re more likely to stick with it, and potentially save you money and hours of frustration down the track.
How Do You Choose a Worm Bin?
1. Determine Your Budget
Worm bins come in a range of prices, from as little as $10 for a DIY worm bin to over $150 for the more expensive. So it’s possible to begin worm farming no matter your budget.
More expensive bins are typically made from higher quality materials, bigger in size, and more efficient. The cheaper ones are usually smaller, but still a great place to start if you’re a worm farm beginner and just wanting to give it a try.
I recommend purchasing the best worm farm you can afford.
2. Choose the Location
The space you have available for your worm bin will determine what type of bin you buy. Many models are small enough if you want to keep the worm bin inside your house. However, if you want your worm bin outdoors, then the space and weather conditions will influence the size and type of bin you choose.
A garage, carport or lean-to is a great place to keep an indoor worm composter to protect it from the elements. Most worm bins on the market are designed for both indoor and outdoor use, but it’s important to check this if you have a specific location in mind.
If in the end you realize you simply don’t have the space for a worm farm, why not consider Bokashi Composting?
3. Consider the Size of Your Household & Number of Worms
One of the main factors to consider when choosing a bin is the size of your household and the amount of kitchen waste produced. A family of four on average produces around 5-7lbs of kitchen waste per week.
As a rough guide, 2lbs of worms can process approximately 1lb of food waste.
Being aware of this will give you an idea of what size worm farm you require and how many worms you’ll need. If anything, start with less worms than you expect you might need as worms reproduce quickly.
4. Calculate the Amount of Bedding Material Needed
Worm bins typically come with instructions on how much bedding material to use.
You’ll need about one cubic foot (144lbs.) of bedding material per cubic foot of worm bin volume, plus some extra for good measure.
Where possible, use recycled materials that you might have on hand such as shredded newspaper, sawdust, or straw.
5. Consider Your Gardening Style
If you have a large garden, opt for a commercial worm composter that allows the constant addition of food scraps all year round.
On the other hand, don’t buy a commercial worm farm if you’re only going to use the bin once a year. Opt for smaller bins if your project is short-term.
6. Know the Warranty and Quality of Your Bin
The best worm compost bins come with a warranty, usually one year. Most companies will work with you to resolve any problems that may arise with your bins.
Check to see if there are any manufacturer recalls before purchasing one.
Sites like eBay and Amazon are good places to find warranted discounted worm bins. As always, check the reviews and see what other people have to say.
7. Check the Odor Containment
Although they are the best composting worms, red wigglers can also be one of the smelliest! Important to keep in mind when considering the type of bin you choose as well as the location.
In saying this, a healthy worm farm should not smell. Almost all worm composting bins come with a lid to prevent odors. Other bins come with a carbon filter, which work by absorbing odors.
Like your home, ensure adequate ventilation for your composter to reduce odor. You can add fresh air through a vent and change the bedding material to prevent odors from building up.
8. Easy to Move
Some worm farms are more moveable than others. An important consideration if you’re looking for a worm farm that gives you the option to move it regularly (for instance if you experience cold winters and want to be able to move your worms indoors).
Some worm composters have wheels or casters to make them easier to move around. You can also try a stackable unit that can easily be separated.
You may need more composting bins later if you become a vermicomposter enthusiast like me! Or if you expect your household size to increase in the future, then having the option to expand your worm farm is a great idea.
Expandable worm farms allow you to do just that, add more sections as needed. You can choose to buy the expansion in your initial purchase or some worm farms allow you to buy expansions down the track as required.
10. Ease of Use & Assembly
A worm composting bin isn’t complicated and should be easy to work with. After the initial setup and bedding, there is not much more to it other than regular feeding.
If the worm farm is too complicated and complex to use, you’ll end up frustrated and only use it a few times. And if you’re not a handy person, ensure you pick a worm composter that is easy to assemble.
Now that you have a good idea of what to look for when choosing a worm bin, let’s get shopping!
