Step 7: Trigger Fruiting
Once the substrate is fully colonized, move the container to a cooler space with some indirect light and slightly lower humidity. Mist regularly.
Within days to a couple of weeks, you should see mushroom pins (baby mushrooms) forming. These will grow quickly—harvest when the caps begin to open.
Step 8: Harvest and Repeat
Harvest mushrooms by gently twisting or cutting them at the base. Don’t pull, as this can damage the mycelium.
Often, you’ll get a second or even third flush of mushrooms if you keep the substrate moist.
Final Tips
- Cleanliness is key: Sterilize tools and containers to prevent mold or contamination.
- Experiment: Try different substrates and mushrooms to see what works best in your home environment.
- Be patient: Mycelium takes time to grow, but once it’s established, it can produce mushrooms for weeks or even months.
Conclusion
Growing mushrooms from grocery store leftovers is a fun and sustainable way to enjoy fresh fungi right at home. With just a few simple supplies and a bit of attention, you can turn kitchen scraps into a rewarding harvest. It’s a perfect project for gardeners, food lovers, or anyone looking to try something a little different.
Happy mushroom growing!
