Why I Love It

After three years of continuous use, this dual chamber compost tumbler remains my top recommendation for most home composters. The two bin system is brilliant: while one side finishes the decomposition process, you're actively adding fresh organic material to the other chamber. This means you get a continuous supply of finished compost without the typical waiting periods between batches. The tumbling mechanism makes turning your compost effortless compared to manually mixing with a garden pitchfork, and I've consistently achieved finished compost in just 2 to 3 weeks during warm summer weather.

Key Features

  • Capacity: 37 gallons total (18.5 gallons per chamber)
  • Dimensions: 25" W x 28" D x 37" H
  • Material: BPA free recycled polypropylene, UV protected
  • Aeration: Deep fins create air channels throughout compost
  • Access: Large sliding doors on both chambers
  • Assembly: Snap together design, no tools required (30 minutes)
  • Weight: 20 lbs empty, supports 150 lbs when filled

Pros

  • Dual chambers enable continuous composting workflow
  • Produces finished compost in 2 to 4 weeks with regular turning
  • Easy 5 crank tumbling mechanism requires minimal effort
  • Elevated design prevents ground pests like rodents and insects from accessing compost
  • Large door openings make adding material and harvesting simple
  • Excellent aeration system speeds decomposition
  • Sturdy steel frame withstands wind and weather

Cons

  • 37 gallon capacity may be limiting for large properties with extensive yard waste
  • Requires more frequent turning (every 2 to 3 days) for fastest results
  • Not ideal for composting large branches or woody material
  • Full chambers can be heavy to tumble (110 to 130 lbs total)

Best For

Suburban homeowners with typical kitchen food scraps and moderate amounts of yard waste. Perfect for home gardeners who want finished compost quickly without the physical labor of manual turning. Ideal choice if you have outdoor space for a 3 foot unit and want a pest proof, odor free composting system that produces consistent quality results.

Real-World Performance

In my real world testing, I composted about 8 gallons of kitchen scraps and yard waste materials weekly. With regular turning every 2 to 3 days, I achieved usable finished compost in 18 to 25 days during hot summer months (outside temp 75 to 85°F) and 3 to 5 weeks during cooler spring and fall weather (50 to 65°F). The dual chamber design meant I harvested 15 to 20 pounds of rich finished compost every 3 to 4 weeks. Internal temperature inside active chambers regularly reached 130 to 150°F, which is hot enough to kill most weed seeds and harmful pathogens naturally through the heat composting process.

Ideal for educators or families wanting to teach children about natural decomposition, the nitrogen cycle, and sustainability practices through hands on learning.

Feeding and Harvest Schedule

I feed my red wiggler worms 3 to 4 pounds of vegetable scraps weekly (coffee grounds, fruit peels, vegetable scraps, crushed eggshells, shredded paper). One pound of composting worms processes about 0.5 pounds of food waste daily once the colony is established. After 3 to 4 months, lower trays contain 5 to 8 pounds of finished worm castings ready to harvest for use in potting soil or as a soil amendment. The compost tea spigot yields 1 to 2 cups weekly, which I dilute 1:10 with water for an incredible liquid plant fertilizer. Annual production: 25 to 30 pounds of worm castings plus several gallons of nutrient rich compost tea for feeding houseplants and vegetable seedlings.

Complete Buying Guide: How to Choose the Right Compost Bin

1. Understanding Compost Bin Types

Tumbling Composters

How They Work: Enclosed drum rotates on a central axis to mix compost contents. Regular turning aerates the compost pile and speeds up the decomposition process through increased oxygen flow to aerobic bacteria.

Pros: Fastest composting speed (2 to 4 weeks), easy turning mechanism, pest proof design, no odor problems, elevated design prevents ground pest access
Cons: Limited storage capacity, more expensive upfront, requires regular turning for best results
Best for: Suburban yards with moderate organic waste, home gardeners wanting quick results
Typical capacity: 30 to 60 gallons

Stationary Bins

How They Work: Open bottom compost bins sit directly on the ground. Add organic materials from the top opening, harvest finished compost from the bottom access door.

Pros: High storage capacity (60 to 100+ gallons), inexpensive price, ground contact allows natural worm colonization, continuous composting process
Cons: Slower decomposition time (2 to 6 months), may require manual turning with a pitchfork, potential rodent access issues
Best for: Large properties with extensive yard waste, patient composters practicing cold composting methods
Typical capacity: 60 to 120 gallons

Worm Composters (Vermicomposting)

How They Work: Red wiggler worms consume organic matter, producing nutrient rich worm castings. Stackable tray system allows continuous harvesting cycles.

Pros: Highest quality finished compost, compact for indoor use, produces liquid fertilizer, educational for families, completely odor free
Cons: Requires purchasing live worms initially, restricted diet (no meat, dairy, citrus), moisture management needed, slower to establish initially
Best for: Apartments, urban homes, indoor composting needs, premium quality castings for container gardens
Typical capacity: Processes 3 to 7 pounds of scraps weekly

2. Size and Capacity Considerations

Calculate Your Needs:

  • Small household (1 to 2 people): 30 to 40 gallon tumbler or 4 tray worm bin
  • Average household (3 to 4 people): 40 to 60 gallon tumbler or 60 to 80 gallon stationary bin
  • Large household (5+ people) or extensive yard: 80 to 120 gallon stationary bin or multiple tumblers

Weekly Organic Waste Estimates:

  • Kitchen scraps: 2 to 5 lbs per person per week
  • Grass clippings (5,000 sq ft lawn): 15 to 25 lbs per mowing
  • Fall leaves: 10 to 30 bags per season depending on tree coverage

Space Requirements: Tumblers need 3 to 4 feet of clearance for rotation. Stationary bins require 3x3 foot footprint minimum. Worm bins fit in 1.5x1.5 foot space indoors or outdoors.

3. Location Planning

Sun Exposure: Partial sun (3 to 5 hours daily) is ideal. Full sun can overheat compost in summer, while full shade slows decomposition.

Convenience: Place within easy walking distance from kitchen and garden. If it's inconvenient, you won't use it consistently.

Ground Surface: Stationary bins need level, well draining soil. Tumblers can sit on patios, decks, or gravel. Ensure stable surface.

Neighbor Considerations: Position 10+ feet from property lines to avoid concerns about odors (though proper composting shouldn't smell). Screen with landscaping if desired.

4. The Composting Process: What You Need to Know

The Carbon to Nitrogen Ratio (The Golden Rule of Composting)

Successful composting requires balancing brown materials (carbon rich) and green materials (nitrogen rich). Aim for roughly a 3:1 brown to green ratio by volume for optimal decomposition and microbial activity.

Brown Materials (Carbon Sources):

  • Dried leaves, straw, sawdust
  • Shredded newspaper or cardboard boxes
  • Dry grass clippings
  • Pine needles, small twigs
  • Coffee filters, paper towels

Green Materials (Nitrogen Sources):

  • Kitchen food scraps (fruit and vegetable peels, cores)
  • Coffee grounds, used tea bags
  • Fresh grass clippings
  • Garden plant trimmings
  • Crushed eggshells

Never Compost: Meat, dairy, oils, pet waste, diseased plants, weeds with seeds, coal ash, treated wood

The Four Requirements for Fast Composting Success

  1. Proper Carbon/Nitrogen Balance: Too much green material creates slimy, smelly compost. Too much brown material creates slow decomposition rate.
  2. Adequate Moisture Levels: Should feel like a wrung out sponge. Too dry creates slow breakdown. Too wet creates anaerobic odors.
  3. Sufficient Oxygen Flow: Turn and mix weekly in tumblers, every 2 to 4 weeks in stationary bins. Aerobic bacteria need oxygen to work.
  4. Appropriate Temperature Range: Active compost piles heat to 130 to 160°F. This high temperature kills weed seeds and speeds material breakdown.

5. Speed Comparison: Cold vs. Hot Composting

Cold Composting (Passive):

  • Add materials whenever available, minimal turning
  • Timeline: 6 to 12 months to finished compost
  • Least effort, slowest results
  • Best for: Large stationary bins, patient gardeners

Hot Composting (Active):

  • Carefully balanced materials, frequent turning (every 2 to 3 days)
  • Timeline: 2 to 8 weeks to finished compost
  • More effort, fastest results
  • Best for: Tumblers, gardeners needing quick compost

Vermicomposting:

  • Worms process scraps continuously
  • Timeline: 3 to 6 months to establish, then continuous harvest
  • Moderate effort, highest quality compost
  • Best for: Indoor composting, small spaces

6. Common Composting Mistakes to Avoid

  • Too much green material: Results in slimy, smelly compost. Fix: Add dry leaves, shredded paper, or sawdust.
  • Too dry: Decomposition stalls. Fix: Add water when turning, or add green materials.
  • Too wet: Creates anaerobic conditions and foul odors. Fix: Add brown materials, turn more frequently, drill ventilation holes.
  • Not turning enough: Center stays hot but edges don't decompose. Fix: Turn weekly in tumblers, bi weekly in bins.
  • Adding inappropriate materials: Meat, oils, dairy attract pests and smell. Stick to vegetables, fruits, yard waste.
  • Pieces too large: Big chunks take forever to break down. Fix: Chop or shred materials before adding.
  • Buying too small: Undersized bins fill immediately and don't maintain heat. Go larger than you think you need.

7. Maintenance and Troubleshooting

Regular Maintenance Tasks

  • Tumblers: Turn 5 to 10 rotations every 2 to 3 days. Check moisture weekly. Harvest when material is dark and crumbly.
  • Stationary bins: Layer materials as added. Turn with pitchfork every 2 to 4 weeks if hot composting. Harvest from bottom door every 2 to 3 months.
  • Worm bins: Feed 1 to 2x weekly. Check moisture (should be like wrung sponge). Harvest lower trays every 3 to 4 months.

Troubleshooting Common Issues

Problem: Bad smell
Cause: Too much nitrogen, insufficient oxygen, or too wet
Solution: Add brown materials, turn more frequently, add ventilation holes if needed

Problem: Not heating up
Cause: Too small, too dry, or improper carbon/nitrogen ratio
Solution: Add more material to increase mass, moisten if dry, adjust brown/green ratio

Problem: Ants or flies
Cause: Too dry or exposed food scraps
Solution: Increase moisture, bury food scraps under brown materials

Problem: Rodents
Cause: Improper materials (meat, dairy) or open access
Solution: Remove inappropriate materials, use enclosed tumbler, add hardware cloth to stationary bin base

Frequently Asked Questions

How long does it take to make compost?

Timeline varies by composting method: Hot composting in tumblers produces finished compost in 2 to 4 weeks with optimal conditions and frequent turning. Cold composting in stationary bins takes 2 to 6 months to fully break down. Vermicomposting requires 3 to 4 months initially to establish, then provides continuous harvests. Temperature levels, moisture content, material size, and turning frequency all impact composting speed significantly. Warmer weather accelerates the process while winter months slow decomposition.

Do compost bins smell bad?

Properly managed compost bins should smell earthy, like fresh forest soil, never foul or putrid. Bad smells indicate composting problems: too much nitrogen material (add brown materials), insufficient oxygen (turn more often), or too wet (add dry materials). Avoid composting meat, dairy products, and oils which create bad odors and attract pests. Tumbler composters and enclosed systems virtually eliminate odor concerns when balanced correctly with proper carbon nitrogen ratios.

What's the difference between a tumbler and a stationary bin?

Compost tumblers are enclosed rotating drums that rotate for easy mixing of materials. They produce finished compost faster (2 to 4 weeks), are pest proof, and work great for moderate waste volumes but have limited storage capacity. Stationary compost bins sit on the ground with large capacity (60 to 120 gallons), cost less money, and allow beneficial ground organisms like earthworms and beneficial bacteria to help naturally, but take longer (2 to 6 months) and may require manual turning with a garden pitchfork or aerating tool.

Can I compost in winter?

Yes, though the decomposition process slows significantly in cold weather conditions. Insulated compost bins maintain some microbial activity down to 40°F. Compost tumblers in sunny spots can stay active longer during winter. Many composters stockpile organic materials in winter and let them decompose slowly, then do hot composting in spring and summer months when temperatures support rapid bacterial growth. Worm bins can be moved indoors to garages or basements for year round composting activity.

Is worm composting better than regular composting?

Worm castings are higher quality compost, richer in beneficial microbes and plant nutrients, but worm composting bins process less volume and have dietary restrictions (no meat, dairy, citrus, onions allowed). Regular composting methods handle larger volumes and accept any plant based organic material. Many home gardeners use both methods: indoor worm bin for kitchen scraps, outdoor compost bin for yard waste. Choose your method based on your available space, the type of waste you generate, and desired end product quality.

How much compost do I need for my garden?

General guidelines: Apply a 1 to 2 inch layer of finished compost to garden beds annually (1 cubic yard covers 150 square feet at 2 inch depth). For making potting mix, use 25 to 30% compost mixed with potting soil and perlite. Side dress vegetable plants with 1 to 2 inches of compost during the growing season. A typical 40 gallon tumbler produces enough finished compost for a 50 to 75 square foot garden bed annually. Scale up production for larger garden areas or increased vegetable production.
