“I’ve recently started getting into worm composting and I’m really enjoying it. However, I’m struggling to figure out the right size and type of bin for my worms. I live in a small apartment and don’t have much outdoor space, so the bin will need to fit in my kitchen or balcony. Can you provide some advice on how to choose the right size bin for my worms, considering my limited space? Thank you so much!” Thanks, Emily, Vancouver, Canada.
How Do I Choose The Right Size Bin For My Worms?
Choosing the right size bin for your worms is a key part of worm composting, especially when working with limited space like Emily in Vancouver. Let’s break it down so you can make an informed decision.
Understanding Your Space
Since Emily mentioned living in a small apartment, space is a huge factor. Here’s what to consider:
- Location: Decide where you want to place the bin. Kitchens and balconies are common choices, but you’ll need to make sure the bin fits comfortably without being an eyesore.
- Ventilation: Worm bins need good airflow to avoid odors and keep worms happy. A balcony may provide natural ventilation, while a kitchen bin may need more ventilation holes.
Establishing Your Worm Population
The number of worms you plan to start with is essential. Generally, you’ll want about 1,000 worms (roughly 1 pound) to start efficient composting. This number helps in determining the bin size.
Emily, for an apartment setting, here’s a quick worm population breakdown:
- 1 Pound of Worms: This equates to about 1 square foot of surface area.
- Food Waste: 1 pound of worms can process about half their weight in food daily.
Calculating Bin Size
Sizing involves a few calculations based on the surface area and volume required. Here’s a simple method:
- Estimate Food Waste: Calculate your weekly kitchen scraps. A family of two generally generates 4-7 pounds of scraps weekly.
- Determine Bin Dimensions: The bin’s surface area should be around 1 square foot for every pound of food waste weekly. If you produce 5 pounds of waste weekly, you’ll need a bin with a 5 square foot surface area.
- Depth Matters: Worms work best in shallow containers. Aim for a bin depth of around 8-12 inches. Shallower bins are easier for worms to navigate.
Material Choices for Bins
Your choice of bin material also plays a role:
- Plastic Bins: Lightweight and easy to manage. Ensure they have plenty of ventilation holes.
- Wooden Bins: Great for breathability but can be heavier. Cedar or pine are good choices as they resist decay.
- Commercial Bins: Options like the Worm Factory 360 are designed for efficiency and ease but may be pricier.
Pros And Cons For Popular Bin Types
Having options is great, but let’s weigh them to help Emily decide:
Plastic Storage Bins
Pros:
- Inexpensive and widely available.
- Lightweight and easy to move.
- Easy to modify (drilling holes for ventilation).
Cons:
- Can retain moisture, leading to potential worm drowning.
- Might require more maintenance to manage ventilation.
Wooden Bins
Pros:
- Natural material that breathes better.
- Looks more aesthetically pleasing.
- Can be built to specific sizes.
Cons:
- Heavier and less portable.
- More expensive and can rot over time if not maintained.
Commercial Worm Bins
Pros:
- Designed for optimal worm composting efficiency.
- Often modular, allowing you to expand as needed.
- Typically includes built-in ventilation and drainage systems.
Cons:
- More expensive upfront cost.
- May be bulkier than DIY options.
Customizing For Limited Spaces
Emily’s limited space in her Vancouver apartment requires customization. Consider these tips:
- Stackable Bins: Vertically stackable bins like tiered systems can save space and increase composting efficiency.
- Use Multi-functional Furniture: Incorporate compost bins into furniture pieces like benches or planters.
- Mini-Bins: Smaller, discreet bins can fit under sinks or on counters without being too obtrusive.
Here’s an example setup for Emily:
“Opt for a three-tiered stackable system in your kitchen. Start with a base layer for drainage, add a composting layer with worms, and a final layer for food scraps. Each tier should be around 1-2 square feet to manage your kitchen waste efficiently.”
Maintaining The Perfect Environment
The right size bin is only the beginning. Maintaining the perfect environment for your worms ensures they thrive:
- Temperature: Keep the bin between 55-77°F (13-25°C). Kitchens typically maintain this range well.
- Moisture Levels: Worms need a moist environment (like a wrung-out sponge). Mist if too dry or add dry bedding if too wet.
- Avoid Overfeeding: Overcrowding can lead to uneaten food and odors. Start with smaller amounts of waste and gradually increase.
Avoiding Common Pitfalls
Emily, like any gardener starting with worm composting, may face some hurdles. Here’s how to tackle them:
Overheating: Small spaces can heat up quickly. Use fans or move bins to cooler spots if necessary. In Vancouver’s temperate climate, this should be manageable.
Should I Have Multiple Bins?
Emily’s limited space might make multiple bins tricky, but there are advantages and workarounds:
- Continuous Composting: Starting with two smaller bins lets you alternate and ensures a steady supply of compost.
- Batch System: Use one bin to compost while another bin “rests.” Once the first is ready, swap them.
Consider using compact, stackable bins if one large bin doesn’t fit your space constraints.
Final Thoughts…
Emily, finding the right size bin for your worms hinges on space constraints, waste production, and personal preference. Starting with a versatile and modular system tailored to your apartment will set you on the path to successful worm composting. Thanks for your question and happy composting!
