Factors to consider

Here is a list of factors to consider as you’re buying a mushroom grow bag.

Type of mushroom

The type of mushroom you want to grow is important to consider. They don’t taste the same way, and you may have preferences.

Grow bag size

The grow bags come in different sizes. One option may not be right for everyone.


The reputation of the company is important to consider. It’s especially the case as you’re dealing with a live product.


Even if you’re growing mushrooms, it’s important to consider the price.


Most mushrooms require specific humidity conditions in order to grow nicely. Make sure the one you’re trying to grow can grow in the conditions you’re doing it in.


Contamination of the grow bag is a real issue. Proper sterilization should be done by the company that you’re buying from so as to avoid problems.


Mushrooms eat the substrate as they’re growing. However, some types require some substrate and other mushrooms do better other substrate.

How to grow mushrooms?

Lion's mane mushroom being grown

It’s certainly not easy to understand how the growing process works. But we can break it down for you. Just like how you need seeds to grow any fruit or flower plant, you need to spawn mushrooms to start a colony of mushrooms. This spawn can be started in mushroom spawn bags. The next step is to use this spawn to grow the rest of the mushrooms. The mushrooms then are grown in fruiting blocks which use sawdust as substrate. After the mycelium takes over the substrate, the fruiting process can begin. These all-in-one bags allow for fruiting also to take place in the same kind of bag.

Let’s take a look at how this happens.

Growing them in a bag

Several important components of this special bag easily accommodate every stage of the growing process. Let’s break them down individually:


The make of the bag is polypropylene, and it is important as it denotes the thickness and temperature resistance of the bag. Since sterilization can also occur in the bag, the plastic should withstand high temperatures.

Filter patch

The filter patch at the top allows fresh air to get to the plant and keeps out contaminants that could ruin it. Mold spores and bacteria could take over your entire efforts, which is what the filter patch stops from happening.

Gusseted shape

The bag’s shape is folded from the inside, which means it lays out flat but is more spacious than it looks. You can store the cultivators within the folds during sterilization.


What sets it apart from regular fabric grow bags is its transparency. The transparent color means you can always monitor the growth of the mushrooms. Even a child could help keep track of the process easily compared to the guesswork in an opaque bag.

The process

The entire growing process can be done in the same bag. Here’s how:

The spawn

These are the seeds of the mushrooms that need to be grown first. Also known as the first-generation grain spawn, they are grown in a bag with a substrate like sawdust or straw. With some inoculants, a large amount of spawn can be produced. Simply fill the bag with the substrate, soil, and inoculants and seal the bag shut. The filter allows for fresh air and humidity inside the bag. Once this is done, you can move on to the fruiting.

The Fruiting

Once the spawn is ready, the bags can also be used for fruiting blocks. In this scenario, the bags will open from the top to allow fresh air and room for the mushrooms to grow. The substrate becomes the fruiting block.

Alternatively, you can move the bags to a fruiting room with the right humidity, air, and lights. Cut some slits in the bag and mist them daily.

In both cases, the bags are exceptional to use.
