Mushrooms can be cultivated hydroponically as fungi. Essentially, growing your own mushrooms hydroponically means that you are using water or other growing mediums instead of soil to cultivate your crop. Hydroponic mushrooms grow quickly and are quite tasty. This article describes two methods of growing hydroponic mushrooms.
Steps
Purchase a mushroom growing kit from your local gardening supply store. Kits are blocks of compressed sawdust that have been saturated with mushroom seeds.
Immerse the mushroom block in a container of cold water. Make sure it is completely immersed; allow several inches of water to cover the top of the block.Advertisement
Allow the block to soak for several hours. The mushroom block has to be thoroughly saturated.
Place the container in a dark, cool spot. The temperature should range between 60ºF and 75ºF (15.6ºC to 23.8ºC).
Harvest your crop of mushrooms. Most hydroponic mushrooms are ready for harvesting in 3 to 5 days.
Let the sawdust block rest for a week and then repeat the process. Immerse the block in cold water and allow it to get thoroughly saturated before you place it in a dark, cool spot.
Reuse the sawdust block each week until you are no longer getting a good harvest. The number of times you can reuse your block will depend on how much time it takes for the nutrients to become depleted.
Toss the sawdust block in your compost pile when it no longer produces mushrooms. You can then start the process over with a new mushroom kit.

Start your mushrooms with fresh mushrooms or mushroom spores. Both can be purchased online or at your local gardening center. These are needed to grow mycelium (fungus). If desired, you can simply purchase liquid mycelium to start the process.
Place small pieces of mushroom, spores or cultures on a sterile Petri dish, which allows the mycelium to grow. The mycelium has to grow until it is strong enough to support a mushroom reproductive cycle.[1]
Allow the fungus to grow in the Petri dish. This will most likely take several weeks.[2]
Transfer the fungus to a tightly packed, sterilized grain, such as wheat or rye. It will take up to 4 weeks for the mushrooms to colonize the grain.[3]
Start harvesting your mushrooms when they have begun to grow on the grain. Check on their progress every few days once they have colonized the grain.
Use your grain seeds to grow more grain. You can then use that grain for your next batch of mushroom spores.

- QuestionWhat temperature do you call 'cold' water? Is it refrigerated? Or just cold from the tap?
Alexis ChamberlainCommunity AnswerCold from the tap. Fungi cannot thrive in water colder than 30 degrees Fahrenheit. - QuestionHow do I become a successful small time mushroom grower?
Community AnswerDo a lot of research, understand the differences in the varieties of mushrooms and how they grow, understand the different sterilization and cleanliness techniques for different types as well. Oyster mushrooms are some of the easiest to grow. You also have to decide where you're going to get your spawn from and what kind of spawn it's going to be based on what growing medium you're going to use. Midwest Mangoes has some information on this on their Facebook page. - QuestionIn the second method of growing mushrooms in water, the next step is to harvest the mushrooms. Do they grow inside the jar?Community AnswerOnce the grain is fully colonized (completely white), then remove the lid and the mushrooms will grow out the top.

Warnings
- Mushrooms can be contaminated with bacteria and other molds. Be sure to cultivate your hydroponic mushrooms in a sterile environment.Thanks
- Your mushrooms won’t grow unless they are placed in a dark spot. If necessary, use room-darkening shades to protect the mushrooms from light.Thanks
- Don’t use chlorinated water to soak your mushroom block. If your tap water is chlorinated, you can fill a container with the tap water and let it sit for 24 hours so that the chlorine will dissipate.Thanks
