Growing mushrooms in buckets is an exciting, budget-friendly way to cultivate fresh fungi at home. Whether you’re interested in growing oyster mushrooms, shiitakes, or other varieties, bucket cultivation offers a simple, efficient method that requires minimal equipment and space. This guide will walk you through the entire process, troubleshooting included, to help ensure a successful harvest.
Why Bucket Cultivation Is Perfect for Beginners
Bucket cultivation is beginner-friendly for several reasons:
- Accessible Materials: You only need a few affordable, easy-to-find items like food-safe buckets and mushroom spawn.
- Controlled Environment: Buckets help protect the substrate and mycelium from contaminants, providing a controlled space for growth.
- Space-Efficient: Perfect for small spaces such as kitchens, garages, or closets.
- Stackable: You can grow more mushrooms by stacking buckets vertically.
With just a little preparation, you can grow mushrooms nearly anywhere!
What You’ll Need
Here’s a list of materials to get started:
- Buckets: Food-safe plastic buckets (5-gallon or smaller) with screw-on lids. Clean thoroughly and drill holes for airflow.
- Mushroom Spawn: Oyster mushrooms are an excellent choice for beginners.
- Substrate: A simple mix of hardwood sawdust and soybean hull pellets works well.
- Drill: Use a drill with a 1/4 to 1/2-inch bit for making holes around the bucket.
- Spray Bottle: Essential for misting and maintaining humidity.
Step-by-Step Guide to Growing Mushrooms in Buckets
1. Prepare the Bucket
- Drill holes around the bucket, spaced 1–2 inches apart, for fresh air exchange.
- Add a few holes near the bottom for drainage.
2. Prepare the Substrate
- Pasteurize your substrate (either the steam or cold water with hydrated lime processes can be used, detailed instructions can be found in our How-To Blog). This process kills contaminants while preserving nutrients.
- Allow the substrate to cool and drain.
- Alternatively, you can use our Ready-to-Use Substrate.
3. Inoculate the Substrate
- Mix the cooled substrate with mushroom spawn, using a spawn-to-substrate ratio of 5–10% for optimal colonization.
4. Fill the Bucket
- Layer the spawn-substrate mixture into the bucket, packing it tightly to eliminate air pockets.
- Cover the bucket with the lid.
5. Incubate
- Place the bucket in a dark, warm area (65–75°F) for 2–3 weeks.
- During this time, the mycelium will colonize the substrate and turn it white.
6. Fruiting
- Move the bucket to a space with indirect light and high humidity (85–90%).
- Mist the bucket 2–3 times daily to maintain moisture.
Troubleshooting Common Issues
Mycelium Isn’t Colonizing
- Cause: Contaminated substrate or improper pasteurization.
- Solution: Use fresh spawn and ensure correct pasteurization temperatures.
Mushrooms Aren’t Fruiting
- Cause: Low humidity or insufficient light.
- Solution: Increase misting and provide 8–12 hours of indirect light daily.
Mushrooms Are Small or Deformed
- Cause: Poor air exchange or high CO2 levels.
- Solution: Check bucket holes and improve ventilation.
Substrate Is Moldy
- Cause: Excess moisture or improper pasteurization.
- Solution: Avoid over-wetting and ensure substrate drains well before inoculation.
Mushrooms Are Browning or Dying
- Cause: Dry substrate or low humidity.
- Solution: Mist more frequently to maintain consistent moisture levels.
Harvesting and Enjoying Your Mushrooms
When ready to harvest, the mushroom caps will fully open or edges will curl slightly upward. To harvest:
- Gently twist and pull mushrooms off the substrate.
- Store them in a paper bag in the refrigerator to keep them fresh.
Buckets often produce multiple flushes. After harvesting, allow the substrate a short resting period, and you might get another round of mushrooms.
