AdewebsIf you’ve ever tried growing mushrooms at home and ended up with a slimy mess instead of a fresh harvest, you’re not alone. I’ve been there too—standing in my shed, scratching my head, wondering if I gave the mushrooms too much water or not enough air. Over time, I learned that half the battle in mushroom growing isn’t just patience, it’s having the right supplies.
Mushrooms are picky little things. They don’t grow the way tomatoes or cucumbers do. They thrive in dark, damp, and carefully controlled environments. Miss one element—too much moisture, poor airflow, wrong substrate—and you’ll be left disappointed. That’s why I put together this list of the 20 best mushroom growing supplies every home grower should have.
Let’s dig in and see what tools can help you turn failed mushroom attempts into a successful, delicious harvest.
1. Mushroom Spawn
Every mushroom project starts with spawn. Think of it like seeds for plants, except it’s the living fungus that kickstarts the whole process. You can buy spawn for different varieties like oyster, shiitake, or lion’s mane. The quality of your spawn sets the tone for your harvest—cheap or contaminated spawn can ruin everything. Always buy from a trusted supplier.
2. Substrate Blocks
Mushrooms need a home to grow, and that home is called the substrate. Substrates can be hardwood sawdust, straw, or even coffee grounds. Pre-made substrate blocks are perfect for beginners since they’re already sterilized and ready for inoculation. Trust me, starting with clean material saves a lot of headaches.
3. Mushroom Grow Bags
These handy plastic bags with breathable filters are a game-changer. You pack them with substrate and spawn, then watch as the mushrooms colonize. The filter patch lets in just the right amount of air without introducing contaminants. They’re cheap, easy, and give you a controlled growing space.
4. Pressure Cooker or Autoclave
One thing you’ll quickly learn: mushrooms hate competition. If bacteria or mold get into your substrate, the crop is ruined. A good pressure cooker sterilizes your materials, killing off any unwanted guests before you add your mushroom spawn. Some growers use an autoclave, but a sturdy pressure cooker works just fine for home use.
5. Humidity Tent
Mushrooms love moisture, but they don’t like sitting in water. A humidity tent, or a simple plastic enclosure, keeps humidity levels high without soaking your crop. I once tried misting my mushrooms every hour by hand—trust me, it gets old fast. A tent does the hard work for you.
6. Hygrometer
You can’t just guess humidity; you need to measure it. A hygrometer shows the moisture levels in your growing space so you’ll know whether to mist more or back off. It’s one of those tools that seems minor until you realize mushrooms won’t fruit if conditions aren’t right.
7. Spray Bottle or Misting System
Handy for keeping things damp. A simple spray bottle works if you’re just starting out. But if you want less maintenance, set up a misting system that automatically sprays water into your growing area. Consistency is key here.
8. Mushroom Fruiting Chamber
This is basically a big box designed to mimic the mushroom’s natural environment. You can buy pre-made chambers or DIY one from a plastic tote. Add some holes for air exchange, maintain high humidity, and your mushrooms will thank you with fat, healthy flushes.
9. Sterile Gloves
Contamination is your number one enemy. Wearing sterile gloves when handling spawn or substrate keeps out bacteria and mold spores. It might feel overcautious at first, but after losing a few bags of substrate to green mold, you’ll see why gloves are non-negotiable.
10. Alcohol Spray (70% Isopropyl)
Another simple but crucial supply. Spritz your workspace, tools, and even your gloves with alcohol before working with mushrooms. Keeping everything clean drastically boosts your chances of success.
11. Laminar Flow Hood (or Still Air Box)
If you’re serious about mushroom growing, a laminar flow hood is the gold standard for sterile work. But for beginners, a still air box—a clear plastic bin with armholes—does the trick. It keeps air still while you work, reducing the chance of contaminants sneaking in.
12. Heat Mat or Temperature Control
Mushrooms don’t like it too hot or too cold. A heat mat can help maintain steady temperatures, especially during colonization. Some varieties are fussier than others, so check the recommended range for the species you’re growing.
13. LED Grow Lights
Not all mushrooms need light, but a little indirect light helps with fruiting. A simple LED grow light works well, especially if your setup is in a dark basement or closet. No need for anything fancy—just a low-energy bulb will do.
14. Digital Thermometer
Like humidity, temperature isn’t something you can just eyeball. A digital thermometer keeps you in the safe zone. Some growers use combo units that measure both temperature and humidity for extra convenience.
15. Sharp Scalpel or Knife
When it’s time to cut into substrate bags or harvest your mushrooms, a clean, sharp blade is your friend. Dull or dirty tools can damage your crop or introduce contaminants. Keep your scalpel sterilized before every use.
16. Mushroom Growing Kits
If you’re brand new, a kit is a great way to dip your toes in. These all-in-one boxes come with spawn and substrate, and you just need to keep them moist. They’re foolproof, and you’ll get to enjoy your first flush without all the setup hassle.
17. Mason Jars
Classic and versatile. Mason jars are often used for grain spawn or small experimental grows. They’re reusable, easy to sterilize, and cheap. Just don’t forget to fit them with breathable lids if you’re using them for colonization.
18. Perlite
This lightweight volcanic rock is often used in fruiting chambers to keep humidity levels steady. Spread it at the bottom of your chamber, mist it regularly, and it helps create that damp, mushroom-friendly environment.
19. Storage Containers for Harvests
After all your hard work, you’ll need a safe way to store your mushrooms. Breathable paper bags or cardboard boxes are better than plastic bags, which trap too much moisture and make mushrooms spoil quickly.
20. Compost Bin for Spent Substrate
When you’re done with a grow, don’t just toss your used substrate in the trash. It’s packed with organic material perfect for your compost pile. Nothing goes to waste, and your garden soil will thank you later.
Handy Tips for Beginner Mushroom Growers
-
Cleanliness is king. Contamination is the biggest reason grows fail. Always clean your hands, tools, and workspace.
-
Don’t drown your mushrooms. Keep humidity high but avoid waterlogging. Mushrooms need damp air, not soggy substrate.
-
Patience pays off. Colonization takes time. If you peek too often or disturb the bag, you risk slowing the process.
-
Homemade vs. store-bought. Kits and pre-sterilized substrates are easier for beginners, but DIY can save money once you’ve got experience.
-
Start with easy varieties. Oyster mushrooms are hardy and forgiving, making them the best choice for first-timers.
FAQs on Mushroom Growing Supplies
1. What’s the easiest mushroom to grow at home?
Oyster mushrooms. They’re resilient, quick to fruit, and don’t need overly strict conditions compared to shiitake or lion’s mane.
2. Do I really need a pressure cooker to grow mushrooms?
Yes, if you’re working with raw grains or bulk substrates. A pressure cooker sterilizes them, killing bacteria and mold before inoculation.
3. Can I reuse mushroom grow bags?
Technically yes, but it’s risky. Contaminants often linger, so most growers use fresh bags for each new cycle.
4. What’s the difference between spawn and spores?
Spores are like seeds, while spawn is already germinated and growing. Beginners should always start with spawn—it’s faster and more reliable.
5. How much does it cost to set up a mushroom grow at home?
You can start small with a $25 kit, or spend $200+ on gear like pressure cookers, grow bags, and humidity tents. It depends on how serious you want to get.
6. Can mushrooms grow without light?
They don’t need much, but a little indirect light helps trigger fruiting. Complete darkness isn’t ideal for most varieties.
7. How often should I mist my mushrooms?
Usually 2–3 times a day, depending on your setup. The goal is to keep the air humid, not soak the substrate.
8. What’s the shelf life of homegrown mushrooms?
Fresh mushrooms last about a week in the fridge if stored in paper bags. Drying or freezing can extend their shelf life.
9. Do I need special fertilizer for mushrooms?
No. Mushrooms feed off their substrate, not soil nutrients. A well-prepared substrate provides everything they need.
10. Can I grow mushrooms outdoors instead of inside?
Yes! Some varieties like wine caps and shiitake do well in outdoor beds or logs. Just keep in mind that weather and pests are harder to control outside.
Final Thoughts
Growing mushrooms at home can feel overwhelming at first. You’ll probably mess up once or twice—most of us do. But with the right supplies, you’ll set yourself up for much better results. Start simple, keep things clean, and don’t be afraid to experiment.
Remember, mushrooms are stubborn but rewarding. Once you see your first flush pushing through the substrate, you’ll forget all about those failed attempts. So, are you ready to roll up your sleeves and give mushrooms another go?
