You can grow mushroom plants at home with a few simple supplies and a little patience.
Growing mushroom plants isn’t as tricky as many people think, and it’s a fun project that rewards you with fresh, tasty fungi right from your kitchen or closet.
Whether you’re a total beginner or a seasoned gardener, learning how to grow mushroom plants at home opens up a whole new world of indoor gardening.
In this post, we’ll explore the easiest ways to grow mushroom plants, the best growing conditions, and the steps you need to follow for a successful harvest.
Let’s dig in and get your mushroom garden started.
How to Grow Mushroom Plants at Home: The Basics
When you want to grow mushroom plants at home, the first thing to understand is that mushrooms aren’t like typical plants you might grow in your garden.
They don’t need sunlight or soil in the traditional sense, and instead they thrive on a substrate like straw, sawdust, or coffee grounds.
The good news is that growing mushroom plants at home is entirely doable, even in a small apartment, as long as you control moisture, temperature, and airflow.
Here’s what you need to know to get started with your own mushroom plants.
1. Choose the Right Mushroom Species
To grow mushroom plants at home successfully, you need to pick a species that suits your environment and experience level.
Oyster mushrooms are the easiest for beginners because they grow fast and tolerate a wide range of temperatures.
Shiitake mushrooms are another great option if you want a meaty texture and richer flavor, though they take a bit longer to mature.
Button mushrooms are classic but a little more finicky, so only try those once you’ve had some practice with easier varieties.
When you grow mushroom plants at home, starting with oyster or shiitake gives you the best chance of a rewarding harvest.
2. Get a Mushroom Grow Kit or Spawn
For your first attempt at growing mushroom plants at home, a grow kit is the simplest route because it comes pre-inoculated with mycelium.
Grow kits include everything you need, like the substrate block, and they take most of the guesswork out of the process.
If you’re more adventurous, you can buy mushroom spawn and mix it with your own substrate to grow mushroom plants at home from scratch.
Either way, the spawn is the “seed” of your mushroom plants, and it’s the living network of mycelium that will eventually produce the fruiting bodies you eat.
Using quality spawn is non-negotiable if you want to grow mushroom plants at home that are healthy and productive.
3. Prepare the Right Substrate
The substrate is the material your mushroom plants will feed on, and it’s a key part of how to grow mushroom plants at home.
Oyster mushrooms love straw or cardboard, while shiitake prefer hardwood sawdust or logs.
You’ll need to pasteurize your substrate to kill off competing molds and bacteria before adding the spawn.
To do this, soak the substrate in hot water (around 160–170°F) for about an hour, then let it cool completely.
Once your substrate is ready and cooled, mix in the spawn evenly, then pack it into a container or bag to start colonizing.
Best Conditions to Grow Mushroom Plants Indoors
Once your substrate is inoculated, you need to create the perfect environment to grow mushroom plants at home.
Mushrooms are sensitive to their surroundings, so getting the conditions right is the difference between a full harvest and a disappointing one.
Here are the key factors that determine whether your mushroom plants will thrive indoors.
1. Maintain High Humidity
Mushrooms are about 90% water, so humidity is the most critical factor when you grow mushroom plants at home.
Aim for 80–90% relative humidity in the growing area, which you can achieve with a humidifier or by misting the area several times a day.
You can also place a humidity tent over your container, like a clear plastic bag with holes, to trap moisture around the mushroom plants.
Without enough humidity, your mushroom plants will dry out, stall, or produce tiny, deformed caps.
2. Control Temperature Carefully
Different mushroom species prefer different temperatures, so check what your specific spawn needs.
Oyster mushrooms grow best between 55–75°F, while shiitake like a slightly warmer range of 60–80°F.
During the colonization phase, you’ll want the temperature on the warmer side to encourage mycelium growth.
Once the substrate is fully colonized, drop the temperature slightly to trigger fruiting for your mushroom plants.
Keep your growing area away from drafts and direct heat sources to avoid stressing the mushroom plants.
3. Provide Fresh Air Exchange
Mushroom plants need fresh air to breathe, just like any living organism, but they’re also sensitive to drafts.
Carbon dioxide builds up in enclosed spaces, and high CO2 levels cause mushroom plants to grow tall, leggy stems with tiny caps.
Give your mushroom plants fresh air by fanning the growing area for a couple of minutes, two to three times a day.
If you’re using a grow bag, open the flaps periodically to let CO2 escape and fresh oxygen in.
Step-by-Step Process to Grow Mushroom Plants
Now that you know the basics, here’s a clear step-by-step guide to grow mushroom plants at home from start to finish.
Follow these steps closely, and you’ll be harvesting your own mushrooms in a few weeks.
This process works for any kit or DIY setup, so let’s walk through it.
Step 1: Inoculate Your Substrate
Mix your mushroom spawn into the prepared substrate thoroughly, making sure it’s evenly distributed.
Then, place the mixture in a container like a plastic tub with holes, or a grow bag with a filter patch.
Keep it in a dark, warm spot (around 70–75°F) for the next one to three weeks.
During this time, the mycelium will spread through the substrate, turning it white and web-like.
Step 2: Induce Fruiting
Once the substrate is fully white with mycelium, it’s time to trigger the mushroom plants to produce mushrooms.
Move the colonized block to a brighter, cooler area, and drop the temperature by about 5–10 degrees.
This temperature change signals to the mushroom plants that it’s time to start fruiting.
You’ll also want to increase humidity to near 90% and introduce fresh air exchange at this stage.
Small pin-like structures will appear within a few days, which are the baby mushroom plants.
Step 3: Harvest at the Right Time
Your mushroom plants will grow quickly, often doubling in size every day once the pins appear.
Harvest them just before the caps flatten out fully, which is when they’re at their peak flavor and texture.
Twist and pull the mushrooms gently from the substrate, or cut them at the base with a clean knife.
Avoid pulling too hard, as that can disturb the mycelium and reduce future yields.
Most mushroom plants will give you two to three flushes, or harvests, over several weeks.
So, How Do You Grow Mushroom Plants at Home?
You can grow mushroom plants at home by selecting the right species, providing a proper substrate, and maintaining high humidity, stable temperature, and fresh air.
The process is straightforward once you understand that mushroom plants don’t need soil or sunlight, but they do need patience and consistent care.
Whether you use a grow kit or build your own setup, the reward of harvesting fresh mushrooms is totally worth the effort.
If you follow the steps and conditions we’ve covered, you’ll be amazed at how easy it is to grow mushroom plants at home.
So grab some oyster or shiitake spawn, set up your growing area, and enjoy the satisfaction of a homegrown harvest.
Your kitchen will thank you, and so will your taste buds.
