No soil is needed. That is probably the biggest advantage of any hydroponically grown plant. The mushrooms will literally grow on water, giving you the opportunity to eat fresh mushrooms every day without a huge garden outside.

Also, unlike other plants, mushrooms do not need light in order to get nutrients for their growth. They do not contain chlorophyll. They do not perform photosynthesis. Therefore, you can set up your mushroom growing kit anywhere.

Another great perk of having a small mushroom farm is the abundance of various nutrients like proteins and antioxidants. Being rich in potassium and magnesium, they can improve your general health.

Hydroponic mushrooms grow faster than the ones you get by growing them in the soil. That is because water is richer in nutrients, and we, the gardeners, are always adding additional nutrients so our hydroponic crops will grow faster, bigger, and healthier than ever.

So, if you want to have fresh mushrooms on your table constantly, hydroponics is the best way to reach that.

Nutrients for Hydroponic Shrooms

what are nutrients for mushroom

Given the fact that, with no other substrate than water, you must add some nutrients in order to get the most out of your mushrooms.

Mushrooms need fats, protein, sugars, and nitrogen in order to grow properly and on time.

The best source of organic material for your hydroponic setup is brown rice flour. Besides that, you’ll need vermiculite, an inert substance that will provide the mushrooms with room to grow.

Some growers can use other ingredients in order to get the best substrate. Rockwool and coco coir is also good inert substance. However, we recommend vermiculite due to its better growing qualities.

The addition of these nutrients will help your hydroponic mushrooms grow faster and bigger. Also, their taste will be better if you’re going to give them all the carbohydrates they need.

What Lighting do You Need?

Fortunately, hydroponic mushrooms do not need to grow lights to develop properly. A simple window with natural daylight will be enough for them to fulfill their light demands completely.

Although mushrooms can be grown with no light at all, the best way is to use at least some light in order to get the best result possible.

Also, you must know that the maximum amount of time your mushrooms should be exposed to light is about 6 hours.

Recommended temperature for growing mushrooms

Compared to light requirements, the temperature is a little more important and complicated.

If we are talking about germination, 75 to 80 degrees Fahrenheit is best.

However, the biggest and fastest growth can be achieved by putting the mushrooms in a controlled environment with around 80 to 85 degrees Fahrenheit and 90% humidity.

Best Systems for Growing Hydroponic Mushrooms

Growing mushrooms from scratch is not an easy job. Therefore, you might consider a system for growing hydroponic mushrooms.

It will take good care of the mushrooms you put in it, and you won’t have any trouble growing them.

How to Grow Mushrooms Hydroponically [Guide]

How to grow mushrooms hydroponically?

Mushrooms are one of the simplest organisms to grow hydroponically. However, there are a few steps where you can mess up their growth and destroy them completely.

Therefore, it’s important you possess enough knowledge in every step of your grower career. Here is a thorough guide on how to grow mushrooms hydroponically.

Solution and Growing Media

First of all, like other plants, mushrooms need a substrate to live and grow on. Some use air stones, other vermiculite, or sawdust. We’ll focus on vermiculite.

Besides an inert substrate, hydronic mushrooms need nutrients. Remember, although many tend to compare mushrooms to plants, they are not the same. Mushrooms do not make their own food. Therefore, they need all the nutrients you can give.

They need fats, proteins, nitrogen, sugar, and carbohydrates in order to grow properly. Hence, the substrate you’ll choose is very important for future growth.

The best choice is to combine brown rice flour with vermiculite and water. After that, you can get on with the inoculation of your mycelium into the sterilized grain.

If you are not using a mushroom kit, the growing process will be a little more complicated. As I said, mushrooms are not plants, and they do not grow like plants at all.

The easiest way to get a mushroom farm from scratch is to start with a fresh mushroom. Put it into a petri dish and let it grow mycelium.

After you do that, you can get the mycelium into a sterilized grain and go on with the growing process.

Growth Stage and Maintenance

Besides substrate, you’ll need to worry about temperature and lightning, a proper growing media for the inoculated vermiculite cakes.

First of all, set up the temperature. Keep the shrooms at 75 to 80 degrees Fahrenheit during germination and increase the temperature to 80 to 85 degrees when they are actively growing. You can also buy a water heater if you live somewhere cold.

The lightning is easy. Just ensure 5-6 hours of daylight every day, and your hydroponic mushrooms should be fine.

Also, if you want your mushrooms to develop new generations, you should get an air pump. It will keep the temperature stable, but it will also help the spores get to other mushrooms.

When and How to Harvest Your Hydroponic Mushrooms?

Usually, mushrooms can be harvested after 4 or 5 days of growing.

After you harvest the mushrooms, you can still use the block by letting it sit idle for a few days and repeat the process.

You can use the block until no more mushrooms grow on it. After that, it is finished. Also, you can let the mushrooms spawn and lead to a bigger mushroom farm.

In order to properly harvest a mushroom, you need to carefully cut the fruiting bodies and leave the mycelium in the ground. The part of the mushroom that we are eating is not actually the main, as we might have thought, so its removal won’t hurt the mycelium.

Consider Using a Hydroponic Mushroom Kit

Consider using a hydroponic mushroom kit

It’s no surprise that growing a mushroom plantation from scratch is not that easy.

Even if you read and know everything there is to know about mushrooms and their development in water, there are numerous possibilities to mess up everything.

If you want a result without any hard work to do, there is a way. It is faster and easier than the traditional one. You can buy a hydroponic mushroom kit.

It will contain a prefabricated block with all the nutrients and substrate that a mushroom needs. More important, it will contain a mycelium that will grow as soon as you put the block in chilled water.

Mushrooms are growing fast, especially in cold water. You’ll be able to harvest your first mushrooms after three or four days.

The biggest downside of a hydroponic mushroom kit is the fact that it isn’t infinite. The nutrients will eventually be spent after 2 or 3 generations of mushrooms, and you won’t be able to refill it.

Final Thoughts

Mushroom growing is not an easy project, especially if it’s hydroponic mushrooms. You need plenty of time and knowledge to harvest at least some mushrooms at the end of the day.

However, after reading this article, you’ll know everything there is to know about hydroponic mushrooms and their gardening. Therefore, you are ready to enjoy the gardening process without any major problems.

Keep in mind that the reward for knowing everything is the fresh and tasty mushrooms you’ll grow on your own. Mushrooms always taste better when they are completely yours!
