What is mushroom farming?

You can refer to mushroom farming as a type of farming known as Mycology, Mushroomology or Fungiculture.

All of the words above means that mushroom farming is the practice of growing the fungi called mushrooms.

Mushroom farming is not the planting and growing of crops.

Instead, it is the growing of fungus to produce mushrooms.

In the past, farmers mostly hand-picked this fungus in the wild. 

However, modern day farming practices (like the use of fertilizers) has hindered the natural growth of mushrooms. 

Other causes of the disappearance of this excellent food source is the change of weather, global warming, deforestation etc.

Currently, there are over 10,000 known types of mushrooms. 

These are grouped as:

  1. Edible mushrooms, 
  2. Medicinal, and 
  3. Poisonous Mushrooms.

For the purpose of this mushroom farming guide, we will focus more on the edible oyster mushroom.

The oyster mushroom is easy to grow and has a very high demand in the market.

What are the nutritional/health benefits of mushrooms?

Mushrooms have a lot of nutritional benefits that make them highly sought after.

It provides nutrients with anti-ageing properties, immune boosters and helps to prevent cancer.

Here are some of the top health benefits of eating mushrooms;

http://skywaysmedia.co.uk/ 1. They contain immune-supporting nutrients:

All types of edible mushrooms contain varying degrees of protein and fibre.

They also contain B vitamins as well as a powerful antioxidant called selenium, which helps to support the immune system and prevent damage to cells and tissues.

There are certain varieties of mushrooms that have the potential in protecting against cancer.

They do this by protecting our cells against DNA damage but also inhibiting tumour formation.

There is also some evidence that they may be beneficial in the treatment and management of neurodegenerative diseases such as Alzheimer’s.

4. May help maintain heart health:

Mushrooms have been shown to have some therapeutic properties that can help to lower cholesterol.

This is evident, particularly in overweight adults.

Also, they produce phytonutrients that can help prevent cells from sticking to blood vessel walls and forming plaque build-up. 

This in turn then helps protect the heart by maintaining healthy blood pressure and circulation.

What are the benefits of starting a mushroom farming business?

You may be asking the question, “Why should I go into mushroom farming?”

Well, here are some valid reasons for you to do so.

1. The startup cost is very low:

You don’t need large farmland that is capital intensive to start mushroom farming.

You can simply use an empty room in your house to grow mushrooms.

Other materials that you need are also very cheap to acquire.

Later in this article, you will see the cost analysis of producing mushrooms and the massive profits that follow.

2. The material for starting up are readily available:

The major raw material you need for this mushroom farming production is sawdust. 

And sawdust is readily available in all wood mills.

Other materials too are easily accessible in the market.

3. Mushroom farms are easy to manage:

In mushroom farming, you don’t need to plough the land nor do you need to do any weeding nor fertilizer application.

Your only job will be to spray water on the blocks using a knapsack and to harvest the mushrooms when they appear.

4. Mushrooms help in agricultural waste management:

Mushroom is a bio-converter that converts organic waste into useful food. 

It makes use of organic wastes such as sawdust, grass, paper, leaves and straws which are all biodegradable. 

5. Mushrooms have a very fast growth rate:

After just six weeks of planting your mushrooms, you can start harvesting.

That is a lot faster than many crops that you can think of.

6. It is a good source of income:

Mushroom farming is a good source of income because mushroom products are highly valued all over the globe.

As a result, you can make money from selling to the local market as well as exporting for foreign exchange.

In Nigeria, the demand for mushrooms is about 1500 tons annually.

However, the production rate is currently just 300 tons per annum which shows great opportunities ahead. 

(P. S.: Stop looking for white-collar jobs).

7. It has lots of nutritional values:

Mushrooms are very satisfying to eat.

They are rich in vitamins, fibre and antioxidants which perform a lot of functions in the body.

Profitable mushroom production business

How do I start a mushroom farm?

Now that you know the benefits of mushrooms and why you need to start mushroom farming, how will you start?

In this section, we will dwell on some of the common terms used in mushroom production.

This will help you as I walk you through each of the steps in mushroom farming.

Also, we will be looking at all the materials that you need to get started.

Let’s go!

What are the commonly used terms in Mushrooms Farming?

1. Fumigation: 

The process of killing pests and insects in your incubating room.

2. Composting: 

The substrate in which the mushroom mycelium grows and on which it produces fruiting bodies. 

It is the product of a fermentation process brought out by a number of mesophilic and thermophilic microorganisms that decompose plant residues and other organic and inorganic matters.

3. Mixing: 

The process of mixing your sawdust, wheat bran and calcium carbonate with water to form a substrate. 

4. Substrate: 

The surface or material on or from which organisms live, grow or obtain their nourishment.

It is also the soil in which mushrooms grow.

5. Bagging: 

The process of putting your substrate inside a bag before pasteurization. 

6. Mushroom Blocks: 

It is the outcome after mixing your substrate and bagging into nylon bags.

These loaded bags are pasteurized or heated to form a solid called a BLOCK.

It is on this block that the mushrooms will germinate from.

7. Pasteurization unit: 

It is a place or space where the blocks are heated for at least 12 hours to kill germs, bacteria and other microorganisms.

8. Spawns: 

This is the seed or fungus that is planted to produce mushrooms. 

9. Mycelium: 

The body of a fungus, most of which is underground or hidden within the wood.

10. Sterilization: 

Any process that removes, kills or deactivates all forms of life (in particular referring to micro-organisms such as fungi, bacteria, spores, unicellular eukaryotic organisms such as Plasmodium, etc.)

11. Inoculation:

This means planting or cultivating your mushrooms spawns into the blocks.

12. Ramification: 

This is what happens when the spawns begin to germinate in the block.

The spawns will spread their roots in the block until the block turns white.

13. Ramified: 

A mushroom block is said to be ramified when it has completely turned white.

14. Incubating room: 

It is a dark room with less light and oxygen where the ramification process of the blocks is carried out.

This room is created by sealing every part of the room with a black plastic bag.

So this room is usually pitch black and you will require a torchlight to move around the room.

15. Fruiting/Cultivating room: 

A cool room or space where the blocks are kept to start mushroom production. 

16. Fruiting: 

This refers to the process where the fully ramified blocks start producing mushrooms.

17. First generation spawn: 

It is the first time mushroom mycelium is transferred onto the grain.

18. First flush: 

Defined as the very first plucking of a Mushroom during harvest season.

What are the recurrent raw materials needed for growing oyster mushrooms?

How to grow mushrooms step by step

In this section, we will dwell on the step by step process of how you can start producing mushrooms.

From the fixed materials we need for the mushroom production, you would have noticed that what we need is a room.

That is because mushroom farming is mostly practised in an enclosed space, unlike other agricultural farming.

Also, the presence of bleach and fumigant is because the process of growing mushrooms requires good hygiene practices.

Therefore, the bleach and fumigant help to eliminate contamination and other parasites or micro-organisms that will affect production.

Generally, the steps in oyster mushroom production include Composting ➡️ Spawning ➡️ Casing ➡️ Spinning ➡️ Cropping. 

But let’s break all of these activities down into steps

Step 1: Prepare your incubating room:

Just as you do land preparation for growing crops like cassava and maize, you will also have to do the same thing for mushrooms.

Only in mushroom farming, you need to fumigate and sterilize the incubating room.

This process is necessary because mushroom production requires the highest level of sanitation and hygiene. 

If there is even the slightest contamination in your mushroom farm, it may cause your mushrooms not to produce.

Even after sterilising this room, you don’t just go inside and out at any time.

Everyone and every single piece of equipment that will go into the incubating room must be sterilized too.

So, if you go out and come inside the incubating room 10 times, then you will have to sterilize yourself 10 times.

It is that serious.

Step 2: Scale the quantity of ingredients that you need:

In this step, you will use the digital scale and the hook scale to measure the number of ingredients that you need.

The ingredients to measure are sawdust, wheat offal and calcium carbonate.

Use the hook scale to measure 100kg of sawdust and 5kg of Wheat offal.

We are using the hook scale here because it is best for scaling heavyweights.

As for the calcium carbonate, use the digital scale to measure only 1kg.

Depending on the dampness of the sawdust, 10 litres of water should be enough to bring it to the right texture. 

Step 3: Screen the sawdust to remove unwanted debris:

After measuring the sawdust, pour it on a clean surface and screen properly to remove all foreign objects in it.

You can do this on a clean cemented floor.

Use your hand or shovel to turn the sawdust gradually to remove stones, wood, nylon and other unwanted objects.

Step 4: Mix the ingredients together:

Here, you are going to mix the sawdust, wheat offal and calcium carbonate together.

Start by spreading the 100kg sawdust on the cemented floor using a shovel to increase the surface area.

After that, spread the 5kg wheat offal and 1kg calcium carbonate all over the sawdust and mix thoroughly. 

Use the shovel to turn the mixture thoroughly until you are sure that the mixture is consistent. 

Next thing is to add water slowly, mix together with your hands and test whether it is well moistened. 

To test whether the water is perfect, hold some of the mixtures in your hand and squeeze tight.

The mixture in your hand should be compacted together and take the shape of the squeeze.

If it does not hold together or breaks easily, then add more water slowly and mix.

On the other hand, if it drips water, then the water content is too much.

Make sure it never gets to this point. 

Step 5: Bag the substrates, scale and seal the nylon:

After getting the right moisture content in your substrate, it is time to load it into small bags.

First, tie the bottom/sealed part of the ice block nylon bags and then turn it inside out.

The essence of doing this is to ensure that substrate fills every corner of the bag.

Now, put some substrate into the bag with your hand.

Hiya the bottom gently on the floor and press down with your hand to ensure that there are no air gaps.

After that weigh the bag with the substrate using the digital scale to get a 1kg measurement.

Repeat this process until you exhaust the entire substrate on the floor. 

Step 6: Treat the blocks with heat (Pasteurization):

After bagging the substrates inside the nylon bags, the end result is what we call mushroom Blocks.

These blocks need to be treated to kill all germs and microorganisms inside of them.

And the best way of treating the blocks is through a process called pasteurization.

This is simply the same thing as heating the blocks consistently for a very long time, usually 12 hours.

To do this, place your metallic drum over the gas burner and add enough water to it.

After that, throw in some huge wood trunks or stones until the water becomes invisible. 

The reason for this is to make sure that the water in the drum does not come in contact with the blocks.

We only need the steam from the boiling water in the drum to pasteurize the blocks.

Once everything is set, stack the mushroom blocks on the stones/wood trunks to fill the drum.

Now, use a black plastic bag to cover the drum properly to ensure that the steam does not escape and the heat is retained. 

Turn on your gas and allow the setup to heat up for 12 hours.

You can use time in this step for accuracy.

After 12 hours, turn off the gas and then leave them set up like that to cool for 24 hours.

Step 7: Inoculation in the incubating room:

This is the most important step in the mushroom production process.

Any mistake that you make at this point will cost you a lot.

Therefore, you have to be really careful to make sure that you don’t bring any contamination into the incubating room.

You must sterilize each of the blocks one by one as you take them out of the drum.

Use a white handkerchief dipped in hypochlorite solution to wipe the body of each block.

Also, before you enter the incubating room, you must sterilize yourself by washing your hands and feet in a bowl of hypochlorite (bleach) solution.

You also need to wear a face mask (to prevent your spit from touching anything) and surgical hand gloves.

Use a sterilized spoon to break the spawns apart into a sterilized bowl.

To inoculate a block, sterilize your hand by spraying some bleach solution on your palm.

After that, use a sterilized spoon to spread some spawns inside the blocks especially, around the edges of the bag. 

Make sure that the spawns are touching each other and form a complete ring around the edges of the block.

Pass the open part of the bag through a PVC pipe and press downwards to leave a small opening the size of the PVC pipe. 

Use a rubber band to hold this arrangement in place and then use cotton wool to close the small opening.

The essence of cotton wool is to prevent contaminants from getting into the block.

After you are done with the block, set it aside in one corner of the incubating room.

Repeat this process for all the blocks.

Step 8: Wait for Ramification to take place:

The blocks in the incubating room should be arranged in such a way that you can easily walk around and sort them.

After arranging all the blocks in the incubating room, lock the room for two weeks for ramification to take place.

After two weeks, come back and check the blocks for ramification and contamination. 

Remember that you must sterilize yourself before entering the incubating room to check.

Also, you must wear a nose mask and sterilized surgical hand gloves.

A block that is ramified should be white in colour while the ones that are not will be in the same state.

To identify a contaminated block, it will have a greenish colour.

So, your job is to remove such blocks immediately and leave the rest to ramify.

Also, some blocks may look blackish and that is because the temperature of the incubating room is too hot.

So, you need to improve on the temperature. 

Putting thatch on the roof can greatly reduce the effect of heat from sunlight.

Normally, it takes 3 to 4 weeks for the mushroom blocks to be fully ramified but the temperature has a huge role to play.

The ideal temperature for mushrooms is between 25 to 27 degrees Celsius.

That is why mushrooms do better during the rainy season and when the weather is cold.

Mushrooms can also be cultivated during the dry season as long as you can control the temperature to not exceed 30 degrees Celsius.

Step 9: Hang the ramified blocks in the fruiting room:

After about 4 weeks of ramification in the incubating room, it’s time to bring the ramified block into the fruiting room.

Unlike the incubating room, the fruiting room allows light and oxygen to get in.

But before we bring the blocks out, we still need to sterilize the fruiting room.

This is where our knapsack will come in handy.

Mix a hypochlorite (bleach) solution poured into the knapsack. 

Then spray the solution generously everywhere in the fruit room including the roof.

Don’t try to minimise how much of the solution you spray in a single spot.

Make sure that you spray on a single spot until the solution starts dripping to the floor.

After thorough sterilisation, bring the ramified blocks out for tying.

The method of tying the blocks is best explained practically in a video.

But the aim is to tie the blocks vertically from the bottom up towards the roof.

After tying, the cotton wool closing the small opening at the top of the block is removed and the excess nylon is cut off.

This is done so that it will be easy to wet the block properly. 

This brings us to the next step.

Step 10: Wet the blocks everyday:

After tying the blocks, wetting the blocks will be your daily job until the block exhausts its usefulness.

You have to wet the blocks first thing in the morning. 

If the weather is hot, like in the dry season, then you need to wet the blocks at least 3 times a day.

To wet the blocks, fill a knapsack with clean water and spray on the blocks.

Make sure that you spray the water all over the blocks for proper wetting.

Step 11: Fruiting, Harvesting, Scaling, Drying and Bagging:

This is the last step in this mushroom farming process.

Once the mushroom block starts fruiting, you need to harvest it every 3-5 days.

Mushroom takes about 6 weeks before it starts fruiting and after the 6th week, it will continue to fruit for up to 6 months.

To harvest the mushrooms from the block, just twist it to break it from its roots.

You can decide to scale the mushrooms and sell them fresh.

But be sure to sell off all fresh mushrooms immediately because mushrooms have a very short shelf-life. 

There are different methods of preserving oyster mushrooms including; freezing, powdering, turning into ketchup, tinctures or pickling.

When refrigerated or cooked, mushrooms can stay up to 10 days.

But the best way to preserve mushrooms is by drying them.

Dried mushrooms have a shelf-life of up to one year.

After drying the mushrooms, you can store them in bags.

Step 12: Marketing of mushrooms:

Marketing is one of the hardest steps in the mushroom farming process.

It is more difficult especially when you stay in an area where people do not know the value of mushrooms. 

The reason for this is the short lifespan of mushrooms.

If you don’t sell off immediately, you will lose your mushrooms.

How profitable is mushroom farming in Nigeria?

The best way to find out how profitable this business is, let’s do a financial analysis of oyster mushroom production using 100kg sawdust.

Here, I will explain how much you will spend and how much profit you will make producing mushrooms.

Usually, 100kg of sawdust will produce 180 blocks weighing 1kg each after mixing.

What is the cost of starting a mushroom farm? 

The cost of materials needed for this project are as follows;

  • 100kg of Saw Dust – 2,000 Naira (not fixed)
  • 5kg of Wheat Offal – 250 naira
  • Calcium carbonate – 50 naira 
  • Gas – 5,000 naira 
  • Sterilization/fumigation which include;

– 1 bottle of 500mls hypo bleach – 600 naira 

– 2 bottles of mucus spirit (600 x 2) – 1200 naira 

– Cotton wool – 400 naira 

Other materials:

  • 2 PVC pipes – 800 naira 
  • Rubber bands – 200 naira 
  • Ice block nylon – 200 pieces for 1500 naira 
  • Workmanship – 3000 naira 
  • Nose mask and gloves – 1000 naira 
  • Spawns (36 bottles) – 36,000 naira  

The total cost of production is 52,000 naira. 

How much can you make from 180 mushroom blocks?

Each mushroom block is expected to produce a minimum of 1.5kg of fresh mushrooms. 

However, we will do our calculations with 1kg per block and an 80% success rate.

1kg of mushroom sells at a minimum price of 1500 naira/kg (ranging between 1500 naira/kg to 3000 naira/kg.

1500 naira by 180kg = N270,000.

That is, if you are wetting the blocks by yourself every day without paying for labour. 

The cost of labour is not fixed. 

Let’s say you pay 10,000 naira per month for wetting; 

6 months by 10,000 naira = 60,000 naira 

Total profit for 180 blocks of mushrooms is (270,000 – 52,000 – 60,000) naira = 158,000 naira.

At 80% success rate, we have;

80% of 158,000 naira = 126,400 naira profit

The 80% success rate is fixed; it could be between 90% to 95% or lower depending on your training and expertise.

Most of the raw materials mentioned are reusable (like the PVC pipes, rubber bands, and nose masks).

What are the challenges in mushroom farming?

The greatest challenge in the mushroom business is sustainability in sales.

Other challenges include the effect of weather, contamination, short shelf-life, ignorance of the health and economic benefits.

What are the solutions to the problems of mushroom farming? 

To solve some of the problems of mushroom farming, some actions must be taken.

Here are a few tips that may help.

1. Form cooperatives for mushrooms farmers: 

This will help in accessing loans, sharing market information, meeting market demands, having a stable price, etc. 

2. Use cooling systems to control temperature:

Mushrooms farming is not rocket science like every other greenhouse farming.

Therefore, to curb the effect of weather, you can regulate the temperature manually and systematically with the aid of a cooling system. 

3. Adequate training for mushroom farmers:

Contamination can be reduced through training, good hygiene and locating your mushroom farm in a less polluted environment, free of rodents.

Pest control, proper fumigation and sterilization should be done after every production.

4. Site the farm close to the market:

The short lifespan of this fungus can be aided by locating your farm close to the marketplace.

Also, proper marketing and networking are very necessary for finding new markets.

In addition, you could dry the mushrooms or produce other mushroom products like seasoning, ketchup, pickles, chutney, etc. 

5. Carrying out networking campaigns: 

Networking is one of the most important offline marketing strategies that boost mushroom sales. 

You can make a mushroom recipe booklet and share it with people.

Samples of your products can be distributed in big malls and variety stores. 

Awareness can also be created through outdoor publicity such as wall hoardings, banners, social media advertisements, influencer and affiliate marketing, insertions in newspapers etc.

What business can you make out of mushroom farming?

There are different businesses that you can start from mushroom farming.

Here are some of them;

  1. Production and sales of spawns.
  2. Production and sales of mushroom blocks.
  3. Fruiting and sales of mushrooms.
  4. Brokerage of Mushrooms 
  5. Duplication of Spawns 
  6. Production and sales of mushroom products like spices, ketchups and pickles. 

Conclusion

I strongly believe that this mushroom training guide is as detailed as possible. 

Now, let’s get our hands dirty because this is a great step to financial sustainability.

Mushroom entrepreneurship is a proven sustainable business that gives up to 40% ROI in the first cycle.

You can even get more than 80%  ROI in the 2nd cycle.

Just like that, the return on investment keeps increasing over time. 

Mushrooms can be consumed in so many interesting and exciting ways which include; frying, grilling, soup and stew preparation, pizza, sandwich, burger e. t. c. 

It is also used to produce ketchup, seasonings, spices, e. t. c.

If you start mushroom farming today, you are well on your way to financial freedom.
