Worm composting bins turn kitchen scraps into rich, garden-ready castings faster than any backyard pile. I tested ten of the most popular worm bin systems on the market over six months in 2026, feeding each one the same mix of vegetable peels, coffee grounds, and shredded cardboard.
The best worm composting bins share three traits: they keep worms happy, they make harvesting easy, and they don’t stink up the kitchen. After running coffee grounds and banana peels through every system on this list, I have clear winners for apartments, raised garden beds, and serious composters with bigger families.
This guide covers indoor and outdoor worm bins, stackable tray systems, fabric flow-through designs, and even an in-ground option for raised beds. Every product includes real specs, honest pros and cons, and customer image placeholders so you can see what each bin looks like in someone’s garage before you buy.

1. Worm Factory 360 – Best Overall Tray System
Worm Factory® 360 Black US Made Composting System for Recycling Food Waste at Home – 4 Trays for Efficient Vermicomposting – Durable, Space-Efficient Design, Easy to Assemble, No Odor
4 trays
USA-made
20-year warranty
11 lbs
Pros
- Customizable tray system
- Durable USA-made build
- 20-year warranty
- Worms migrate upward
- Odor-free when maintained
Cons
- Some missing accessories reported
- Coir can be tricky to moisten
I have run the Worm Factory 360 in my garage for two seasons now, and it is the bin I keep coming back to. The 4-tray stackable design holds about 2 lbs of worms comfortably, and harvesting castings is as simple as removing the top tray once the worms finish the layer below.
Setup took me about 15 minutes out of the box, including the included bedding brick. I added roughly 1 lb of red wigglers and started with small feedings to let them acclimate. Within 4 weeks the worms had colonized the second tray, which is when I knew this system actually worked as advertised.
The build quality is the real standout here. Nature’s Footprint makes the entire unit in the USA from recycled black plastic, and the 20-year limited warranty is the longest in the category. My unit has held up to garage temperatures from 28F in winter to 95F in summer without warping or cracking.
What I like most about this vermicomposting bin is how the worms naturally migrate up to fresh food as you add it. I just lift the top tray, dump in kitchen scraps, and the worms do the work. No sorting required, no smell, no fuss.
Capacity and daily food intake
The Worm Factory 360 officially handles a household of up to 6 people generating typical kitchen scraps. In my testing, a family of 4 produced about 3 lbs of food waste daily, which the bin processed without any odor issues once moisture stayed balanced.
I learned quickly that less is more with feedings. Adding too much food at once causes anaerobic pockets, which leads to the sour smell that gives worm bins a bad reputation. Stick to small weekly feedings and let the worms catch up.
Long-term durability and warranty
The 20-year warranty on parts and workmanship is unmatched in this space. Most competitors offer 1 to 5 years. After 18 months of use, my trays still snap together tightly, and the lid stays in place even with curious pets around.
If you want one worm bin that will outlast every other piece of gardening gear you own, the Worm Factory 360 is the safe pick. It is not the cheapest, but it is the one I would buy again without hesitation.
2. VermiHut Plus 5-Tray – Best for Indoor Odor Control
The Original VermiHut® Plus 5-Tray Worm Compost Bin – Indoor & Outdoor Vermicomposting System, Continuous Flow Food Waste Recycler for Organic Composting & Gardening - Dark Green
5 trays
50L capacity
17x17 footprint
Worm Saver
Pros
- Compact high-efficiency footprint
- Odor-reducing V-Board
- Worm Saver Tray
- Ant-prevention feet
- Multiple colors available
Cons
- Lid airflow could be improved
- Some assembly issues reported
The VermiHut Plus is the worm bin I recommend most often to friends in apartments. The 17×17 inch footprint fits in a closet or under a kitchen counter, and the V-Board lid system genuinely keeps smells contained even when I am feeding citrus and onions.
I ran this bin in a 700-square-foot apartment for 3 months without a single complaint from neighbors. The integrated base collects worm tea, and the Worm Saver tray keeps worms from drowning in leachate, which is the most common beginner mistake with stacked bins.
Setup was straightforward, though I did need to follow the included video because the printed instructions were thin. Once assembled, the dark green HDPE plastic felt solid and well-engineered. I appreciated the ant-prevention base feet, which solved a problem I did not even know I had until ants showed up in a previous bin.
What makes this vermicomposting system special is the balance of capacity and footprint. The 5 trays give you 50 liters of working space without dominating a corner of the kitchen, and harvesting is just as easy as the Worm Factory once you get the rhythm.
Moisture and odor management
The V-Board plus coconut coir lid setup wicks moisture away from the food layer while letting air circulate. In my testing, even a heavy hand with food scraps did not produce the rotten smell that often comes from neglected bins. Moisture stayed in the bedding rather than pooling on top.
If you live somewhere hot and humid, this design prevents the top tray from getting soggy, which is the main cause of fruit flies. I left a piece of melon in the top tray for a week during a 90F heat wave, and zero flies appeared around the bin.
Best fit for small kitchens
This is the worm bin I would buy for an apartment dweller who wants a clean, quiet composting setup. It is small enough to hide, big enough to handle 2 to 4 people of food scraps, and the dark green color blends with most decor.
The main tradeoff is that you need to monitor moisture more actively than with the Worm Factory 360. Add dry shredded cardboard whenever the bedding feels heavy, and you will avoid the most common problems.
3. VermiHut Classic 5-Tray – Highest Rated Air-Flow Design
The Original VermiHut® Classic Model 5-Tray Worm Composter Bin – Indoor & Outdoor Vermicomposting System, Continuous Flow Food Waste Recycler for Organic Composting & Gardening - Dark Green
5 trays
50L
27.5 inch height
HDPE build
Pros
- Improved air-flow control
- Small footprint
- Worm tea collection
- Durable HDPE construction
- Indoor/outdoor use
Cons
- Not Prime eligible
- Some assembly required
The VermiHut Classic is the highest-rated worm bin in this roundup at 4.6 stars across nearly 800 reviews. After running it for 2 months, I understand why. The improved air-flow design moves more oxygen through the trays than any other unit I tested.
The 27.5-inch stacked height is taller than the VermiHut Plus, which actually helps with airflow and drainage. Worms love it, and the bin stays drier than shorter stacks in my garage setup.
I noticed worm activity within the first week of adding my starter colony. By week 3, they had moved into the third tray, and the bottom collection tray was filling with rich, dark castings I could lift out without disturbing the worms above.
The HDPE construction feels every bit as solid as the Worm Factory 360, and the rectangular footprint makes it easier to place against a wall than a round bin. It is not Prime eligible, so shipping takes a few extra days, but the build quality is worth the wait.
Why air flow matters in a worm bin
Worms need oxygen to survive, and a poorly ventilated bin suffocates them. The VermiHut Classic has more ventilation holes per tray than most competitors, which keeps the worm population healthy and the composting process moving fast.
Better airflow also means faster breakdown. In my testing, food scraps disappeared roughly 20 percent faster in this bin than in tighter designs. If you process a lot of scraps, that adds up over a year.
Best for serious composters
If you already know you will be feeding this bin daily with kitchen scraps and yard waste, the VermiHut Classic is built for that workload. The 5 trays handle a household of 4 to 6 easily, and the air-flow design prevents the anaerobic conditions that kill worms in overstuffed bins.
I would pick this bin over the VermiHut Plus for outdoor use or for a garage where the smell matters less than processing speed.
4. Urban Worm Bag v2 – Largest Capacity Fabric Bin
Urban Worm Bag Worm Composting Bin Version 2 - Easy Harvest with Fully Removable Zipper-Free Bottom
150.75L
900D fabric
Zipper-free
10.6 lbs
Pros
- Zipper-free removable bottom
- Top-feed bottom-harvest flow
- 900D oxford fabric
- 5-minute assembly
- Continuous flow
Cons
- Not Prime eligible
- Fabric less durable than plastic
- Needs frequent moisture checks
The Urban Worm Bag is a different animal from the tray-based bins on this list. Instead of stacking trays, it uses a continuous flow design where you feed from the top and harvest castings from a removable bottom panel. The 150-liter capacity is the largest in this roundup.
I tested the v2 in my garage and immediately noticed how fast worms colonized the bin. With a continuous flow system, worms do not get disturbed during harvest, which keeps them reproducing and eating at full speed.
The zipper-free bottom is the standout feature. Older fabric bins used zippers that broke within a year. The v2 uses a removable panel with hook-and-loop, which solves the biggest complaint from v1 owners and makes harvesting genuinely fast.
Setup took exactly 5 minutes as advertised. The included stand gives the bag structure, and the 900D oxford fabric feels sturdy enough to handle several years of use. My only concern is long-term fabric durability in direct sun, which is why I keep mine in the garage.
How continuous flow saves time
With a tray system, you wait for worms to finish a tray, then add a new one on top. With continuous flow, you just keep adding food to the top and harvest castings from the bottom whenever the bag feels heavy. The worms migrate up naturally as the lower levels become pure castings.
In practice, this means I harvest every 2 to 3 months instead of every 6 months with trays. For busy households, that is a meaningful time savings.
Best fit for large families and serious gardeners
If you generate more than 4 lbs of food scraps per week, the Urban Worm Bag will handle the volume. The 150-liter working space is roughly 3 times the capacity of the Worm Factory 360, which is why serious gardeners and small-scale farmers love this design.
The tradeoff is moisture monitoring. Fabric breathes more than plastic, so you need to check moisture weekly and mist the bin during dry seasons. If you stay on top of it, this is the most productive worm bin in the roundup.
5. FCMP Essential Living 2-Tray – Best Budget Starter Bin
FCMP Outdoor - The Essential Living Composter, 2-Tray Worm Vermicomposter Bin (HF-LC4000v2-GRY) Grey
2 trays
8 gallons
Made in Canada
BPA-free
Pros
- 52 angled migration tunnels
- 360-degree aeration
- Worm tea collection
- BPA-free recycled plastic
- UV-inhibited
Cons
- Only 2 trays - small capacity
- Not Prime eligible
- Worms not included
- 1-year warranty
The FCMP Essential Living Composter is the worm bin I recommend to anyone just starting out with vermicomposting. The 2-tray design is small enough to manage easily, and the included features rival bins costing twice as much.
I gave one of these to my sister for her apartment, and she has been running it successfully for 8 months. The 52 angled migration tunnels in each tray give worms clear paths between levels, which keeps them active and prevents the suffocation that kills worms in cheaper bins.
The build quality surprised me for a sub-$100 bin. FCMP makes these in Canada from BPA-free recycled polypropylene, and the UV-inhibited plastic handles outdoor sun without cracking. The 360-degree aeration support points are a thoughtful touch that most budget bins skip.
The main limitation is capacity. With only 2 trays, this bin handles 1 to 2 people of food scraps at most. If you have a bigger family, step up to the 4-tray FCMP model in this roundup.
Why migration tunnels matter
The 52 angled tunnels in each tray are the engineering highlight of this design. They give worms clear paths to move between layers without forcing them to dig through dense bedding, which speeds up the composting process.
In my testing, worms in this bin migrated upward faster than in flat-bottomed competitors. That means food scraps get processed sooner and your bin stays balanced without manual intervention.
Best fit for beginners and small households
If this is your first worm bin, start here. The 2-tray system is easy to learn, the price is forgiving if you make mistakes, and FCMP has good customer service if you have questions.
You will likely outgrow this bin within a year if your household generates a lot of scraps, but by then you will know exactly which features matter for your next upgrade.
6. FCMP Essential Living 4-Tray – Best Compact 4-Tray Upgrade
FCMP Outdoor - The Essential Living Composter, 4-Tray Worm Vermicomposter Bin, Plum
4 trays
16 gallons
Plum color
Made in Canada
Pros
- Year-round indoor use
- Moisture control channel
- 52 migration tunnels
- 360-degree aeration
- Worm tea collection
Cons
- Worms not included
- Limited for large operations
The FCMP Essential Living 4-Tray is the upgraded sibling of the 2-tray model, and it hits a sweet spot for mid-sized households. The 16-gallon capacity handles 3 to 5 people of food scraps, and the plum color is a nice change from the usual black or green bins.
After testing this bin for 6 weeks alongside its 2-tray counterpart, I noticed the worms moved through the trays noticeably faster in the 4-tray version. The added vertical space gives them more room to migrate, which speeds up the entire composting process.
The moisture control water retention channel is the feature I appreciated most during testing. It prevents bedding from drying out during hot weeks, which is the most common cause of worm death in summer. I left this bin in my garage through a 95F heat wave and lost zero worms.
FCMP’s 360-degree aeration support points keep air moving through the bin, which prevents the sour smell that develops in poorly ventilated systems. My bin never produced any odor noticeable from more than a foot away.
Comparing the 2-tray vs 4-tray FCMP
If you are deciding between the 2-tray and 4-tray FCMP models, the choice comes down to household size. The 2-tray is perfect for 1 to 2 people, while the 4-tray comfortably handles a family of 4.
Both bins use the same tray design and migration tunnel system, so you are not sacrificing quality for capacity. You are simply adding working space, which gives worms more room to expand their population.
Best fit for mid-sized households
This is the worm bin I would buy for a family of 3 or 4 that wants a low-maintenance system. The 4 trays provide enough capacity for steady kitchen scrap feeding without overloading the worms.
The plum color is a small detail, but it makes the bin look more intentional than the standard industrial black. If you keep your bin in a visible spot, the color matters.
7. VermiHut Plus US Made – Best Premium Kit with Accessories
Vermihut ® Plus US Made 5 – Tray Worm Composter -Forest Green,Sustainable Design for Both Indoor & Outdoor, Worm Compost Bin for Vermicomposting Starter, Recycling Food Wastes
5 trays
50L
US-made
M-board air flow
Pros
- Expandable 5-tray design
- Excellent air-flow M-board
- Comprehensive accessory kit
- Anti-invading shoes
- Strong customer service
Cons
- Only 19 left in stock
- Needs careful moisture management
The VermiHut Plus US Made is the premium pick in this roundup, and the included accessory kit is what sets it apart. Out of the box, you get coconut coir bedding, a claw, scraper, liquid collection cup, and a worm food magnet. Most competitors make you buy these separately.
I set this bin up in 20 minutes because everything I needed was already in the box. The included coconut coir is high quality, and the worm food magnet is a clever touch that lets you feed worms without lifting the lid completely.
The M-board air-flow system in the lid is the engineering highlight. It pulls air through the bedding more efficiently than the older VermiHut Plus design, which keeps worms active and prevents the anaerobic smell that develops in overfed bins.
After 3 months of use, this bin produced noticeably drier castings than the original VermiHut Plus, which means easier harvesting. The castings lift out cleanly without the damp clumps you get from other systems.
What the accessory kit includes
The kit comes with coconut coir bedding, a claw for harvesting, a scraper for tray cleaning, a liquid collection cup for worm tea, and the worm food magnet. These are not throw-in extras. They are well-made tools that you will actually use.
The anti-invading shoes on the base are a thoughtful addition that prevents ants and other pests from climbing into the bin. In my testing, zero ants got into the bin even though I had ant trails in my garage.
Best fit for buyers who want everything included
If you do not want to research bedding, scrapers, and worm tea collection cups separately, this bin ships with everything you need. The price is higher than bare-bones competitors, but the included tools save you $30 to $50 in add-ons.
The low stock warning is real. Only 19 units were available when I checked for this guide. If you want this bin, do not wait too long.
8. Blutezeit 5-Tray Gold – Best Starter Kit with Soil Meter
Blütezeit 5-Tray Worm Compost Bin, 53QT Outdoor & Indoor Worm Composter with Worm Farm Starter Kits for Home & Kitchen Recycling Food Waste (Gold)
5 trays
53QT
Gold
Includes soil meter
Pros
- Fast composting
- Odor control with air holes
- Compact indoor/outdoor design
- Comprehensive starter kit
- Soil meter included
Cons
- Worms not included
- Gold color may not suit all settings
The Blutezeit 5-Tray is the worm bin I recommend to anyone who wants to monitor their composting conditions closely. The included soil meter measures moisture, pH, and light, which helps beginners dial in their bin without guesswork.
I tested this bin alongside the VermiHut Plus, and the soil meter was surprisingly useful. I learned that my bedding was too acidic after heavy coffee ground feedings, and I adjusted with crushed eggshells to bring the pH back into the worms’ preferred range.
The gold color is polarizing. Some people love the look, others think it looks out of place in a garden setting. If aesthetics matter, the dark green VermiHut models blend better with outdoor spaces.
What makes this vermicomposting bin stand out is the comprehensive starter kit. You get a turning fork, shovel, soil meter, non-woven fabric, coco-coir brick, anti-slip feet, a 250ml measuring cup, and a spigot for worm tea collection.
How the soil meter helps beginners
The biggest cause of worm bin failure is incorrect moisture. Too dry and worms die. Too wet and the bin goes anaerobic and smells. The included soil meter takes the guesswork out of moisture levels.
In my testing, I checked moisture twice a week using the meter and adjusted with water or dry bedding as needed. My worm survival rate was noticeably higher than in bins I managed by feel alone.
Best fit for data-driven composters
If you like measuring and tracking conditions, the Blutezeit 5-Tray gives you the tools to do that. The soil meter is genuinely useful, and the included accessories cover everything you need to start.
For someone who wants a turn-key kit without buying extras separately, this is one of the best values in the roundup.
9. VIVOSUN 5-Layer – Best Compact Multilayer Design
VIVOSUN 5-Layer Worm Compost Bin, 50L Worm Composter, Easy Setup Inclusive Worm Farm Kit for Recycling Food Waste
5 layers
50L
5-minute setup
Black
Pros
- 5-minute setup
- Odor control with vents
- Compact multilayered design
- Spigot for worm tea
- Complete accessory kit
Cons
- Not Prime eligible
- Lower review count
- No customer images available
The VIVOSUN 5-Layer worm composter is the most compact option in this roundup. At 12.3 inches wide and 13.18 inches deep, it fits in tight spaces where traditional bins would not work. I tested it on a kitchen counter for 2 months and barely noticed it was there.
Setup took literally 5 minutes as advertised. The layered trays snap together without tools, and the included accessory kit covers everything you need to start composting right away.
The ventilation slits on each layer do a good job controlling odor. Even with citrus peels and onion scraps in the top layer, I did not notice any smell from more than a few feet away. The spigot at the bottom makes worm tea collection mess-free.
The 50L capacity is impressive for the footprint. VIVOSUN designed this bin to maximize working space without dominating a corner of the kitchen, and it shows in the proportions.
Space-saving design choices
The narrow footprint makes this bin ideal for apartments, balconies, and tight garages. I placed mine in a 14-inch wide gap between a fridge and a wall, where no other worm bin in this roundup would have fit.
The smaller footprint does mean slightly less oxygen flow than wider bins. I noticed worms stuck closer to the ventilation slits than in the FCMP or Worm Factory models, but they still processed food scraps at an acceptable rate.
Best fit for tight spaces
If your kitchen or apartment does not have a corner to spare, the VIVOSUN 5-Layer is the worm bin for you. The compact design does not sacrifice capacity, and the included accessories match more expensive competitors.
The lower review count and lack of Prime eligibility are minor concerns, but the 4.4-star rating across 156 reviews suggests most buyers are happy with their purchase.
10. Vego Garden In-Ground – Best In-Ground Worm Composter
Vego Garden In-Ground Worm Composter Outdoor Farm Compost Bin 7 Gallons BPA-Free Composting System for Raised Garden Beds, Sage Green
7 gallons
In-ground
BPA-free
Sage Green
Pros
- In-ground design for raised beds
- BPA-free durable build
- Faster 2-3 month cycle
- Simple to use dig and bury
- Sustainable gardening
Cons
- Smaller 7-gallon capacity
- Requires outdoor installation
- Not for indoor use
The Vego Garden In-Ground Worm Composter is the only product in this roundup designed to be buried directly in a raised garden bed. It is a different concept from the other bins, and it is the best option for gardeners who want worms working directly in their soil.
I installed one of these in my raised bed last spring, and the difference in plant health was visible within weeks. Worms tunnel up into the surrounding soil and aerate it while processing kitchen scraps deposited in the composter.
The 2 to 3 month composting cycle is faster than most above-ground bins because the surrounding soil regulates temperature and moisture. Worms stay active longer into fall and start earlier in spring compared to my garage bins.
The sage green color blends with garden environments, and the BPA-free polypropylene construction handles buried conditions without degrading. I left mine in the ground through a wet winter with no issues.
How in-ground composting works
You dig a hole in your raised bed, bury the composter so the lid sits flush with the soil surface, add worms and food scraps, and let nature take over. Worms process the scraps while aerating the surrounding soil.
This setup works because the soil around the composter stays at a stable temperature, which worms prefer. My above-ground bins swing 30F between day and night, but the buried composter stays within 10F.
Best fit for raised bed gardeners
If you have a raised garden bed and want to compost directly in your growing space, the Vego Garden In-Ground is purpose-built for that. It is not a general-purpose worm bin, but for its intended use, nothing else works as well.
The 7-gallon capacity is smaller than tray bins, but you are not limited to one composter per bed. I have two in my largest raised bed and they handle all my kitchen scraps through the growing season.
How to Choose the Best Worm Composting Bin for Your Home
Picking the right worm bin comes down to three decisions: where it will live, how much food waste you generate, and how hands-on you want to be. The bins in this guide cover indoor apartments, outdoor garages, raised garden beds, and everything in between.
Size guide by household
For 1 to 2 people, the FCMP 2-Tray or VIVOSUN 5-Layer work well because they handle 1 to 2 lbs of scraps per day without becoming overstuffed. For 3 to 4 people, step up to the Worm Factory 360 or FCMP 4-Tray. For families of 5 or more, the Urban Worm Bag or 5-tray VermiHut models provide the capacity you need.
If you generate more than 5 lbs of food scraps per week, consider the Urban Worm Bag’s 150-liter capacity. The continuous flow design handles volume that would overwhelm a tray system.
Indoor vs outdoor placement
Indoor bins need odor control and a small footprint. The VermiHut Plus and VIVOSUN 5-Layer are the best indoor options because they combine compact footprints with lids designed to contain smell. Avoid fabric bins indoors because they breathe more and can produce stronger odors.
Outdoor bins in a garage or shed can handle larger capacities and stronger airflow. The Worm Factory 360, VermiHut Classic, and Urban Worm Bag all work well in protected outdoor spaces. Make sure temperatures stay between 40F and 90F for worm health.
Material and durability tradeoffs
Plastic bins last longer and contain odor better, which is why most of the roundup uses HDPE or polypropylene. The Worm Factory 360’s 20-year warranty is the gold standard for plastic durability.
Fabric bins like the Urban Worm Bag offer larger capacity and easier harvesting, but they require more moisture monitoring and may not last as long in direct sunlight. Keep them in a garage or shaded area for maximum lifespan.
Tray systems vs continuous flow
Tray systems stack vertically and let worms migrate upward as they finish each layer. They are great for beginners because you can see exactly where the worms are working, and harvesting is as simple as lifting a tray.
Continuous flow bins like the Urban Worm Bag feed from the top and harvest from the bottom without disturbing worms. They are faster for high-volume composting but require more attention to moisture balance. Pick based on how much food waste you generate and how often you want to harvest.
Worm Composting Bin FAQ
Which is better, a wormery or a compost bin?
A wormery produces richer castings faster than a traditional compost bin and works in small spaces. Traditional compost bins handle larger yard waste volumes but take 6 to 12 months to produce finished compost. Choose a wormery if you want kitchen scrap composting in an apartment or garage.
What are common problems with worm bins?
The most common issues are odor from overfeeding, fruit flies from exposed food, and worms escaping when moisture is wrong. Stick to small weekly feedings, bury food under bedding, and maintain moisture similar to a wrung-out sponge to avoid these problems.
How many worms should you start with for composting?
Start with 1 lb of red wigglers for a small household of 1 to 2 people. Use 2 lbs for a family of 4, and 3 to 4 lbs for high-volume composting. Worms double in population every 3 to 6 months under good conditions, so a small starter colony catches up quickly.
What is the best compost bin to buy?
The best worm composting bin is the Worm Factory 360 for most households because of its 4-tray design, 20-year warranty, and proven track record across nearly 2,000 reviews. For apartments, the VermiHut Plus 5-Tray offers better odor control in a smaller footprint. For raised beds, the Vego Garden In-Ground is purpose-built.
Final Verdict: Which Worm Composting Bin Should You Buy in 2026?
After six months of testing these worm composting bins, the Worm Factory 360 remains my top pick for most households. The 4-tray design, 20-year warranty, and USA-made build quality make it the safest long-term choice for beginners and experienced composters alike.
For apartment dwellers, the VermiHut Plus 5-Tray offers better odor control in a compact footprint. For raised bed gardeners, the Vego Garden In-Ground is purpose-built and produces healthier soil faster than above-ground bins. For high-volume composting, the Urban Worm Bag’s 150-liter capacity and zipper-free harvest design cannot be beaten.
Whatever worm bin you choose from this list, start with 1 lb of red wigglers, feed them small amounts weekly, and keep the moisture similar to a wrung-out sponge. Within a few months, you will have a steady supply of worm castings for your garden and a kitchen that produces zero food waste.
