About Growing Mushrooms
Mushroom growing is becoming more popular than ever. People grow them for cooking, health, or even small-scale food production. It’s no longer just for commercial farmers—anyone can grow mushrooms at home with the right setup. Using tools like Mushroom Grow Bags and Monotubs makes it easy to cultivate species such as oyster or lion’s mane in clean, controlled environments. This guide explains what supplies you’ll need, why each one matters, and how to expand your mushroom growing once you’re ready for bigger harvests.
How Mushroom Farming Works
Growing mushrooms is different from growing vegetables or herbs. But the goal is similar. Mushrooms are fungi, not plants. They do not need sunlight or regular soil to grow well. Instead, they grow by breaking down organic matter. Mycelium, which is their thread-like root structure, makes this possible. Knowing how mushrooms grow is the first step. Then you can run a successful farm using the right equipment.
Here are the four main steps in how mushrooms grow:
1. Inoculation
Inoculation means putting mushroom culture, like spores or live mycelium, into a growth material. This material is also called a substrate. This step is sensitive. It is very important to keep things sterile. Bacteria or mold can get in by accident. These can outgrow your mushroom culture and ruin a whole batch.
You will need special mushroom growing tools. These include sterile syringes, scalpels, and disposable gloves. A still air box (SAB) or a laminar flow hood gives you a clean work area. This helps stop contamination when you move cultures.
2. Colonization
After inoculation, the culture spreads its mycelium through the substrate. It "eats" the organic material it is growing on during this time. Colonization takes time. It can take 1 to 3 weeks. This depends on the type of mushroom and the substrate used.
Use the right containers, such as mason jars, grain spawn bags, or grow blocks. These help keep the air flowing and the environment contained. You should watch humidity and temperature closely. Use a thermometer and a hygrometer to do this.
3. Fruiting
Once the mycelium has fully grown through the substrate, growers make changes to the environment. For example, they increase humidity and fresh air. This makes the mushrooms start to grow. This is when the mushrooms appear and get bigger.
At this stage, you will need good humidity control, airflow, and sometimes light. These help the mushrooms form well. This is when mushroom growing supplies are important. These include humidifiers, grow tents, or automated misting systems.
4. Harvesting
When to harvest depends on the mushroom type. But usually, you pick them a few days to a week after they start growing. If you pick them too early or too late, the quality can drop. It can also spread spores that might contaminate other growing areas. Use clean scissors or knives to cut mushrooms at their base.
Knowing what step you are in helps you avoid expensive mistakes. It also makes sure you use the right mushroom farming tools at the right moment.
Basic Mushroom Growing Supplies Everyone Needs
No matter how much experience you have, you will need certain mushroom farming equipment. This equipment is key to starting and keeping a grow operation going well.
Spores vs. Liquid Cultures
Fungi grow from spores. These are tiny cells, much like seeds. Growers usually use either dry spores or liquid cultures to start growth.
- Spores: These are good if you want to try new types. But they are not as reliable for beginners. Spores must sprout first. This can take time and might not work well if conditions are not good.
- Liquid Culture: This is a solution rich in nutrients. It already has mycelium growing in it. It lets the substrate colonize faster. Also, it has a better success rate. This makes it the best choice for new growers.
Tip: If you are just starting, choose commercial liquid cultures from trusted suppliers. They lower risk, make growth faster, and are easy to keep sterile.
Substrate Materials
The substrate gives your mushrooms their nutrients. The best material changes based on the mushroom type and what you want to grow. Common substrates are:
- Straw: People use this most often for oyster mushrooms. It is easy to find and cheap.
- Hardwood sawdust or chips: Shiitake, lion's mane, and other mushrooms that like hardwood grow best on this.
- Grain (usually rye, millet, or brown rice): People commonly use this to make spawn.
- Manure-based compost: This works well for agaricus types, like white button and portobello mushrooms.
Getting the substrate ready in the right way is very important. You need to pasteurize or sterilize the substrate with a pressure cooker or autoclave. This makes sure your mushrooms do not have to fight harmful germs.
Inoculation Tools
Handling cultures in a sterile way is key to successful mushroom farming. Here is a basic list of what you need:
- Sterile Scalpel and Syringe: Use a scalpel to cut agar plates. Use syringes to inject liquid culture into grain spawn.
- Alcohol Lamp or Butane Torch: This sterilizes tweezers, scalpels, and syringe needles.
- Latex or Nitrile Gloves: These stop contamination from your hands.
- 70% Isopropyl Alcohol and Sterile Wipes: Use these to wipe down surfaces and tools very well.
Optional but helpful: a hepa-filtered laminar flow hood for the cleanest work possible.
Containers and Grow Bags
After inoculation, your cultures need a safe spot to colonize. Two common choices are:
- Pint or quart-sized mason jars: These are cheap and you can use them again. They are good for small amounts of grain spawn.
- Filter patch spawn bags: You throw these away after use. But you can grow more with them. They have built-in filters. These let gases pass through without needing other changes.
For fruiting, think about:
- Monotubs: These are large plastic storage bins. They have added air holes and filters. They are simple and great for a lot of mushrooms.
- Grow blocks: These are rectangular packages that come already sterile. Mycelium grows in them, and then mushrooms grow right from them.
Cultivation Environment Tools
Controlling the environment can lead to a good harvest or a failed one with contamination. These tools help during both colonization and fruiting:
- Thermometer & Hygrometer: These help you keep track of temperature and humidity.
- Humidity Dome or Tent: These keep humidity inside for small grow setups.
- Automated Humidifier: You will need this for bigger, ongoing grows.
- Misting Bottle: This is good for cheap setups where you add humidity by hand.
Sanitization Equipment
Keeping things sterile is very important. Always have these ready:
- 70% Isopropyl Alcohol: This is the best for cleaning surfaces.
- Bleach (diluted 1:10 with water): Use this for equipment that is not sensitive and for cleaning floors.
- Nitrile Gloves and Face Mask: These help keep out germs that people carry.
Tools Specifically for Hobby Growers
Mushrooms are very popular now. This makes it easier for people to start growing them without spending a lot of money. If you grow on a small scale, you can choose mushroom growing tools that fit your budget, space, and are simple to use.
Pre-Sterilized Grow Kits
These kits are good for people just starting or who have little space. They come with:
- Pre-colonized grain or sawdust spawn
- Sterilized substrate
- Fruiting container or bag
They are ready to grow mushrooms. Just spray them with water and wait. Studies show beginners have over a 70% higher chance of success with these kits than with do-it-yourself ways (Martínez-Carrera & Morales, 2016).
DIY Fruiting Chambers
Do-it-yourself fruiting chambers are easy to get, cheap, and you can be creative with them. The best choices include:
- Modified Plastic Tubs (Monotubs): Drill 1/4-inch holes around the bin. Fill them with polyfill for air to get in.
- Mini Greenhouses: Add zipper covers and an ultrasonic humidifier. This makes them easier to use.
- Small Grow Tents: Add shelving and LED lights if needed.
Tip: A $10 digital timer can make humidity cycles automatic. This means you do not need commercial systems right away.
Commercial-Grade Mushroom Farming Equipment
Do you plan to start a business or sell mushrooms to restaurants, co-ops, or farmers markets? If so, then growing more and being efficient becomes very important.
Advanced Sterilization & Clean Air Tools
- Laminar Flow Hood: This uses HEPA-filtered air across your work area. It helps keep contamination very low.
- Still Air Box (SAB): This is a cheaper option. It lets you move cultures without contamination.
- Pressure Cooker or Autoclave: Use these to sterilize grain, substrate, and tools reliably in bigger batches.
A 23-quart pressure cooker is a good first choice for small commercial farms.
Temperature and Air Control Equipment
In a commercial setup, controlling the environment keeps things steady and gets you the most mushrooms.
- Evaporative or Ultrasonic Humidifiers: These keep humidity levels between 85–95%. The exact level depends on the mushroom type.
- CO₂ Monitors and Filters: These get rid of gases that build up. Too much gas can stop mushrooms from growing.
- Portable HVAC or Mini-Splits: These help keep temperatures steady all year.
Proper temperature and air control can increase how many mushrooms you get by up to 40% (Royse, 2017).
Things You Need to Grow More
- Stainless Steel Shelving: This is strong and does not rust. It makes good use of vertical space.
- Substrate Pasteurization System: These use hot water baths with electricity or propane. They let you pasteurize large amounts of substrate safely and quickly.
- Digital Environmental Sensors: These watch and record temperature, CO₂ in the air, and humidity in different areas.
Add simple task automation, like misting timers or air circulation plans. This makes work more efficient without needing more staff.
Guides for Specific Mushroom Equipment
Each type of mushroom grows best in certain conditions. Using the right substrate and matching the environment makes growing easier.
| Mushroom Type | Preferred Substrate | Notes |
|---|---|---|
| Oyster | Straw or coffee grounds | Grows fast, good for beginners |
| Shiitake | Hardwood sawdust or logs | Needs longer colonization period |
| Lion’s Mane | Hardwood + wheat bran mixes | Needs high humidity, sensitive to temperature |
| Reishi | Sawdust or logs | Best in outdoor or greenhouse setups |
| Enoki | Sawdust + supplements | Needs a cold shock to grow mushrooms |
Pro Tip: Start with oyster mushrooms. They grow fast, are easy to handle, and give quick success. This builds your confidence.
Setting Up Your Grow Space
You can grow mushrooms almost anywhere, with some creativity and rules:
- Closets & Pantries: These are cheap and it is easy to control their temperature.
- Basements: These are naturally cool. They are good for growing mushrooms with small humidity changes.
- Converted Sheds & Garages: Using these lets you get more mushrooms and grow on a bigger scale.
Prepare the area by adding:
- Plastic-lined walls and floors for splash protection
- Passive air filtration (box fan + HEPA furnace filter)
- Dehumidifier for dry climates, humidifiers for dry ones
Optional Extras That Make Life Easier
Get better mushroom growing supplies as you get more experience or grow more mushrooms:
- Heat Mats or Incubators: These make colonization faster in cold places.
- Petri Dishes and Agar Media: Use these to grow clones or get strains without contaminants.
- Timers and Relays: These make lighting, humidifying, and even airflow plans automatic.
- CO₂ Meters: These help keep gas exchange right for the best mushroom growth.
What It Costs to Start Growing Mushrooms
How much it costs to start changes a lot depending on what you want to do. Here is a list of costs:
| Item | Approx. Cost Range |
|---|---|
| Pre-Sterilized Grow Kit | $30–$80 |
| Humidity Tent or Plastic Bin | $20–$100 |
| LED Scheduling Light | $10–$40 |
| Thermo-hygrometer | $10–$20 |

| Spawn Bag or Mason Jar | $5–$15 per unit |
Total: $50–$250 for hobby growers.
For commercial micro-farms:
- Facility Build-Out: $500–$2,500
- Environment Systems: $1,000+
- Grow Hardware: $500+
Tip: Do it yourself and reuse things when you can. Many containers and shelves can be used again with some creative thinking.
Maintenance & Troubleshooting
Things do not always go as planned. Be ready with tools for:
Contamination Control
- Hydrogen Peroxide (3%): Use this to treat spots where you see mold starting.
- Alcohol Spray: Wipe down surfaces and gear daily with this.
- Clean Room Curtains or HEPA Filters: These keep mold spores and airborne bacteria away from your growing area.
Pest Management
- Sticky Traps: These catch gnats and mites before they spread everywhere.
- Neem Oil: This is a natural spray. Use it to stop bugs from moving into outdoor mushroom patches.
Know when to compost your substrate. After 2-4 harvests, you get fewer mushrooms. Also, the risk of contamination gets higher.
Tips to Get More Mushrooms
Make your money work even harder:
- Spread out your colonization jars weekly. This gives you harvests all the time.
- Only use recycled spawn once.
- Label bag types, when you inoculated them, and the mushroom strain.
- Add lighting times for mushrooms that need light (e.g., shiitake or pink oyster).
- Write down things like temperature, how fast colonization happens, and how well fruiting works. This helps you make changes based on facts.
