Buying Guide: What is the Best Worm, Composting Bin?
Worm composters have a variety of sizes, shapes, and colors. So, it’s best to know the features to look for before landing on any eye-catchy products.
There are four main design subcategories:
Continuous flow-through Composters
This type of worm bin functions by banking on the fact that worms feed in an upward motion. Thus, they help lower the maintenance practices required between harvesting sessions.
Worms tend to eat waste closer to the surface while excreting their castings deeper in the ground. Continuous flow-through models employ this mechanism by facilitating waste addition at the surface and having a bottom opening for harvesting mature castings.
This enhances the efficiency of your worms since they don’t have to look throughout your bin for food. Instead, they facilitate swift composting as garden-like conditions allow them to maintain their usual behaviors.
Tray system worm composter
A tray system is arguably the most comfortable worm composting method, thus perfect for a newcomer.
The setup for trays is a breeze. Fill a tray with your preferred bedding, add in organic kitchen scraps until the contents near the top. Upon filling the tray, load up the second one with bedding, then place it above the previous tray.
After your worms finish the food in the bottom tray, they’ll naturally migrate upwards to the top trays, leaving behind trays with nutrient-rich castings.
Hanging worm bin composters
Hanging worm bins function like continuous flow-through composters. The only difference is they use a bag, unlike the standard continuous flow design.
Food waste goes at the top, while the bottom opening allows the collection of worm castings.
Hanging bins are ideal for indoor use as you can hang them on a support with a collection bin beneath. Some composters can hang on a door making an excellent worm farm for a small space.
Outdoor worm compost bin
These have several varieties. There two main subcategories:
Above-ground bins are large or flow-through models. Temperature control is via insulation and depends on the heat produced during worm composting to keep your worms warm.
Below-ground bins are less prone to temperature changes and provide similar conditions found in natural worm habitats.
Although not as popular as before, some people dig windrows/vermitrenches, extensive trench systems in a garden, for vermicomposting. These trenches function similarly to other vermicomposting units. They accommodate bedding material with the continuous addition of food scraps on top of the pile.
Your worm bin’s footprint is a crucial consideration. Composters have varying sizes, and the position you want to place your unit affect the bin options you’ll go for. Almost any size is ideal for an outdoor setting, basement, or garage but compost bins of around 15″ by 15″ are suitable for indoor vermicomposting.
If you’ll keep your worm bin outdoors, it’s vital to get a long-lasting model. Go for worm composters with UV resistance to prevent plastic from brittleness. If your composter has wood parts, ensure they have a weather-proof coating.
Indoor vs. outdoor
Some composters have a rugged look suitable to withstand outdoor use. Others, however, have a more pleasing appearance hence excellent for indoor use.
The location of your bin’s vents also affects where to use it. Rain tends to penetrate large vents, which results in a moisture issue that makes outdoor use difficult. Indoor composters need optimal aeration to prevent foul odor.
Collecting Worm Tea/Leachate
The most nutritious fertilizer you’ll get from your compost is worm tea. Some composters have a tap that eases leachate collection. Others feature drainage holes and a collection tray.
First-timers to vermiculture may find estimating the number of materials they’ll add and the amount of casting produced challenging to do. Several worm bins permit the addition of expansion sets. Should your space run out before you are ready to collect the first casting, such units allow expansion.
Which is better, compost bin or worm farm?
Both a compost bin and a worm farm have numerous advantages to the environment. The best between them depends on your needs and which features you are after. Below is a look at both systems to ease your decision.
a) Composting Bin
A compost bin relies on the natural decomposition process. Upon decomposition, materials in your compost bin turn to humus, a vital ingredient for sustainable gardening.
In a composting bin, we place many layers of materials that break down to form nutrient-dense soil. The major decomposition drivers in composting bins include microorganisms, water, and air.
One thing about a compost bin is that setting up is hassle-free. Moreover, you can place your compost bin directly in the garden to get maximum benefits.
Advantages of using a compost bin include:
- They minimize food wastage.
- Provide a free gardening resource.
- Increases your garden soil levels.
- The composting materials are readily available.
- The setting up process is hassle-free.
- You can have plants growing in your compost.
- You save money from additional purchases like worms.
- You don’t need to be too cautious about composting conditions, as is the case with vermicomposting operations.
- If you have a sizeable food scrap heap, you don’t need to worry about periodic addition like adding worm food in vermiculture.
- It allows the decomposition of some foods that aren’t great for worms. For instance, you can place citrus, onions, eggshells, and oily foods without worry.
b) Worm Farms/Vermiculture
Vermiculture involves placing composting worms in confined spaces, adding food remains and other materials that worms thrive on.
Worms are sensitive to high acidity levels, so it’s best to avoid adding citrus, onion, and other similar foods to your worm farm. Adding small quantities of these accidentally is alright, but they will drive your worms out of the enclosure in large amounts.
Some of the best components to add to your vermicomposting bin include:
- fruit and vegetable matter
- shredded papers like cardboard
- rotted horse manure
Worms produce highly nutritious worm castings and worm tea, an enriched brown liquid excellent for soil enhancing and plant fertilizer.
A worm farm may be a bin, old bathtubs, or a bucket without a base.
The advantages of vermiculture are:
- They provide nutrient-rich worm castings that are also excellent enhancers of the soil environment, promoting neutralization of soil acidity and alkalinity.
- They provide worm tea, which is one of the best natural fertilizers.
- Worms ensure high compost efficiency. Since they move within the system, you won’t turn your compost, saving your time and energy.
- Fertilizer from a worm bin has more nutrients than that from the usual composting process. Thus, you’ll have healthier plants.
- Since you have to place food in a sequence, you won’t overfill your bin. This results in better decomposition and enhanced aeration, minimizing odor product.
- Worm farms allow for a continuous composting process, unlike the other composting method where you have to stop adding materials after a while.
- You can sell excess worms to anglers and other gardeners and earn income while getting high-quality fertilizer.
- A worm composting bin allows you to attain the ideal temperature range as it’s portable, unlike a compost pile.
Should I put worms in my composter?
Vermicomposting is an excellent venture to consider. With a worm colony in your composter, you’ll have faster decomposition. Hence you can compost more products within the same amount of time than when relying on the typical composting process.
Besides, you now know the many advantages a worm farm can offer you. Having worms in your composter is better than when relying on bacteria and fungi action.
However, you ought to have certain conditions in your worm composter for optimal operation:
- Your composter should have an adequate oxygen supply.
- Keep your bedding moist but avoid excess water. Have a proper balance between nitrogen and carbon. Most of your food scraps are green materials; hence add things like shredded cardboard and dry leaves, and grass clippings.
- You should feed your worms the right foods. Avoid oils, meat, dairy, salty, and acidic materials.
What is the best composter?
The Urban Worm Company impresses us with its Urban Worm Bag invention, unlike everything on the market. It has a breathable fabric for optimal moisture and oxygen conditions. The sturdy frame secures it off the ground to ease casting collection and prevent pests from invading your bin.
How does Vermicomposting Work?
Numerous organic residues are excellent for feeding your worms to produce castings. Worms consume these wastes and lower your compost’s volume by 40 to 60 percent.
Each worm eats about half to an equivalent of its body weight. It then produces casting s which is half of what it consumes. Castings have a neutral pH and have a moisture range of about 1/3 to 2/3 of the mass.
Then the amount of nutrients in castings depends on the food source for your worms. The worm species you use also affect the quality of the castings in part. Red worms/wigglers and nightcrawlers are a popular choice because of their high-quality droppings.
Vermicomposting is an excellent way to get rid of your leftovers. It promotes a better world free of methane pollution, which is a common occurrence in a landfill. With one of our top vermicomposting bins, you’ll have a hassle-free time maintaining it, harvesting your castings, and feeding in everything organic.
