Vermicomposting Mastery

Produce premium worm castings—the most biologically diverse and plant-available soil amendment you can make. Turn waste into wealth while creating nature's perfect fertilizer.

What You'll Learn

This comprehensive online course teaches you everything from setting up your first bin to producing commercial-quality castings and teas that deliver measurable results in your soil.

Core Skills: • Design and build vermicompost systems for any scale—countertop bins to commercial flow-through operations • Select the right worm species for your climate and goals (Eisenia fetida vs. other options) • Create optimal conditions: moisture, temperature, pH, and bedding management • Develop feeding schedules that maximize production without problems • Recognize and prevent common issues: fruit flies, odors, worm die-off, and escape behavior • Master harvesting methods from simple manual separation to continuous flow-through systems • Assess casting quality through visual and biological indicators • Brew and apply worm casting tea for maximum biological impact • Scale operations from hobby bins to commercial production • Calculate ROI and pricing for selling castings

• Multiple bin design options with construction plans

• Real-world troubleshooting and problem-solving from my Maine operation

• Downloadable guides, checklists, and tracking tools

• Complete vermicomposting manual (PDF)

• 90 days of email support

What's Included:

• Vermicompost Bin Construction Plans (5 different designs from small-scale to commercial flow-through)

• Worm Species Selection Guide

• Feeding Schedule Templates by system size

• Bedding Material Comparison Chart

• Moisture and Temperature Management Protocols for indoor operations

• Complete Troubleshooting Decision Tree

• Harvesting Methods Comparison (manual to flow-through systems)

• Casting Quality Assessment Checklist

Who This Course Is For

Perfect for:

• Gardeners wanting the highest-quality soil amendment available

• Homesteaders looking to turn waste into resources

• Market growers seeking premium biological inputs

• Cold-climate growers who need year-round compost production

• Anyone with garage, basement, or indoor space for controlled production

• Educators teaching composting and soil health

• Entrepreneurs interested in selling premium castings

• Anyone frustrated with slow traditional composting or outdoor limitations

• Farms wanting to produce their own liquid biological feeds

Not sure if this is right for you? Vermicomposting requires regular attention and works best for smaller volumes. If you process large amounts of material or want hands-off composting, thermal or cold composting might be better options.

Why Vermicomposting?

Unmatched Biology: Worm castings contain the highest diversity of beneficial microorganisms of any compost type

Nutrient Density: Immediately available NPK plus enzymes, growth hormones, and humic acids

Year-Round Production: Works indoors in any climate, any season—perfect for Maine winters

Climate Independent: No need for outdoor space or seasonal waiting

Space Efficient: Produce significant amounts in garages, basements, or spare rooms

Zero Waste: Transform kitchen scraps, paper, cardboard into premium amendments

No Odor (When Done Right):Properly managed systems are completely odor-free

Profitable: Premium castings sell for $10+ per pound!

Course Outcomes

By the end of this course, you'll be able to:

• Set up and maintain thriving worm bin systems in indoor environments

• Keep worms healthy, productive, and reproducing consistently through all seasons

• Feed efficiently without creating anaerobic conditions or pest problems

• Choose the right harvesting method for your scale—from manual to flow-through

• Recognize high-quality finished castings vs. immature material

• Brew biologically active casting tea with proper protocols

• Troubleshoot and solve problems before they crash your system

• Scale production to match your needs—hobby to commercial flow-through operations

• Calculate true costs and pricing if selling castings

• Manage indoor systems for optimal production in any climate

Frequently Asked Questions

Do worm bins smell? No! A properly maintained vermicompost system is completely odor-free—it should smell like fresh forest soil. Odors indicate problems (too wet, overfed, or anaerobic conditions), which we teach you to prevent and fix.

Can I keep worms indoors year-round? Absolutely! I run my commercial flow-through operation in my garage in Maine through harsh winters. Worms thrive at room temperature (55-77°F), and indoor systems give you complete climate control and year-round production.

What kind of worms do I need? Red wigglers (Eisenia fetida) are the standard composting worm. We cover why they're ideal, where to source them, and how to maintain healthy populations in indoor systems.

How much space do I need? A small countertop bin (2'x1'x1') works for a single person's kitchen scraps. My commercial flow-through system fits in a standard garage. We provide designs for every scale from tiny apartment bins to commercial operations.

What can I feed them? Fruit and vegetable scraps, coffee grounds, tea bags, crushed eggshells, shredded paper, cardboard. We provide a complete "yes/no" feeding guide and explain why certain items should be avoided.

How long until I get finished castings? Typically 2-4 months from feeding to harvest in traditional bins. Flow-through systems provide continuous harvesting—you're always adding material at the top and harvesting finished castings from the bottom. I demonstrate both methods in the course.

What if my worms die? We cover all the common causes (temperature extremes, moisture problems, toxic materials, overfeeding) and how to prevent them. The troubleshooting module addresses every worm die-off scenario with solutions from real-world experience.

Can I make money selling castings? Yes! Premium worm castings sell for $20-40 per cubic foot. The course includes scaling strategies, production cost calculators, and pricing guidance based on commercial operations. I share real numbers from my own production.

What's a flow-through system and do I need one? A flow-through system allows continuous harvesting from the bottom while feeding at the top—no manual separation needed. It's the most efficient method for commercial production. We cover when it makes sense to upgrade and how to build or buy one.

How is this different from your Composting Mastery course? This course focuses exclusively on vermicomposting with deep dives into worm biology, indoor system management, flow-through operations, and commercial scaling. Composting Mastery covers vermicomposting plus thermal and cold methods. If you only want worms, this course is perfect. If you want all three methods, choose Composting Mastery.

What about harvesting from flow-through systems? Flow-through systems are the easiest harvesting method—simply remove finished castings from the bottom regularly. I demonstrate my commercial flow-through operation and show you exactly how harvesting works at scale.

Can I use castings for making tea? Yes! Module 8 covers complete casting tea protocols including brewing parameters, equipment, quality control, and application methods. Casting tea is one of the most powerful liquid biological feeds available.

Do I need special equipment? For basic systems: just bins, bedding material, and worms. We provide DIY construction plans that cost $20-50. For flow-through systems, I cover commercial options, DIY builds, and ROI analysis to help you decide what's right for your scale.

What if I travel or go on vacation? Established worm systems can go 2-3 weeks without feeding. We teach you how to prepare bins before leaving and maintain them with minimal intervention.

Does indoor production work in cold climates like Maine? Yes! That's exactly where I operate. Indoor systems maintain stable temperatures year-round regardless of outdoor conditions. I share specific strategies for garage and basement operations in cold climates.

Is there a money-back guarantee? Yes. If you're not satisfied within the first 30 days, we'll refund your purchase in full, no questions asked.
