Mushroom growing is a rewarding and sustainable way to produce fresh, healthy food at home. One of the most important factors in the success of a mushroom growing operation is the proper use of water.
Water is essential to the growth of mushrooms, but it’s also easy to overdo it, which can lead to poor yields and even crop failure or mold.
In this blog post, we will explore how much water to use during both the substrate phase and the fruiting phase of mushroom growing. We’ll take a look at mushroom substrates, how to properly hydrate them, and how to maintain the ideal moisture levels during the fruiting phase.
Additionally, we will cover advanced commercial growing misting methods at the end.
Whether you’re a beginner or an experienced mushroom grower, this post will provide you with valuable information to help you get the most out of your mushroom growing operation. You may learn something important about hydration in mushroom growing

Water content of the substrate in the first stage of mushroom growing
When setting up your mushroom growing operation, it’s important to pay close attention to the amount of water you add to the substrate. The substrate is the material that the mushrooms grow on, and it needs to be hydrated to the right level in order for the mushrooms to thrive.
One key thing to keep in mind is that mushrooms prefer a substrate that is about 60-70% water. This means that for every 100 grams of substrate, you should add 60-70 grams of water. It’s best to err on the side of slightly drier than too wet, as mushrooms can suffer from issues such as bacterial or mold growth if the substrate is too wet.
For some mushrooms, you will want to move toward the 30% range. It’s important to do the research on what your mushrooms prefer before creating your substrate.
One way to gauge the hydration level of your substrate is to use the “squeeze test.” Simply take a small amount of substrate in your hand and give it a gentle squeeze. If water droplets appear on the surface, the substrate is likely too wet. If it feels dry and doesn’t produce any droplets, it likely needs more water. This is a popular method to test water content.
Another way is to use a hygrometer to measure the humidity and moisture content of the substrate.
It’s also important to note that different types of mushrooms have different water requirements. For example, oyster mushrooms prefer a wetter substrate than shiitake mushrooms. Before you begin growing a specific type of mushroom, be sure to research its ideal water requirements so you can adjust your substrate accordingly.
Adding the right amount of water to the substrate is crucial for successful mushroom growth. A good rule of thumb is to aim for a substrate that is 60-70% water. Use the “squeeze test” or a hygrometer to gauge the hydration level of the substrate, and keep in mind that different types of mushrooms have different water requirements.
How much to mist during the colonization phase in mushroom growing
Mushroom cultivation requires a specific level of humidity for the spores to germinate and colonize the substrate. One of the most effective ways to maintain the right level of humidity is through misting.
Check out this post from Intergalactic Mushroom on watering mushrooms.
During the colonization phase, the mushroom mycelium is growing and spreading through the substrate. The mycelium is sensitive to dryness and needs a consistent level of humidity to thrive. A good humidity level during the colonization phase is around 85-90%.
The frequency of misting will depend on the environment in which the mushrooms are being grown. Factors such as temperature, ventilation, and the type of mushroom being grown will all play a role in determining how often to mist. A general rule of thumb is to mist 2-3 times per day during the colonization phase.
It’s also important to note that the misting should be done with water that is at room temperature. Cold water can shock the mycelium and halt growth.
When misting, it’s essential to monitor the humidity level after each misting to ensure that it stays within the ideal range. A hygrometer can is used to measure humidity levels.
In summary, maintaining the right humidity level during the colonization phase is crucial for successful mushroom growth. A good humidity level during this phase is around 85-90%. Misting 2-3 times per day with room temperature water and fine misting can help achieve this humidity level. Monitoring humidity levels after each misting is essential to ensure that it stays within the ideal range.
Misting during the fruiting stage of mushroom growing
Introduction to Misting in Mushroom Growing
Misting plays an important role in the fruiting stage of mushroom cultivation. The fruiting stage is when the mushrooms develop and mature, and the right level of humidity is essential for healthy and productive mushroom growth.
Similar to the above, the ideal humidity level is around 80-85% during the fruiting stage of mushrooms. This level of humidity is met by misting 2-3 times per day in an average environment.
The frequency of misting will depend on the environment in which the mushrooms are being grown, and the type of mushroom you are growing. For example, some mushrooms may require more frequent misting than others. Again, do your due diligence when it comes to mushroom growing for good results.
While misting is necessary to maintain the right humidity level, too much misting can lead to problems such as bacterial or mold growth. Therefore, mist with care and monitor your humidity levels as best as you can to ensure accuracy, especially in commercial operations!
Timing and tips for misting your mushroom grow
Another important consideration is the timing of misting. The best time to mist is early in the day, before the lights come on (assuming you have lights).
This allows the mushrooms to dry off before the lights are on, which reduces the risk of bacterial or mold growth.
Misting should also be done with water at room temperature. Cold water can shock the mushrooms and halt growth. And when misting, it’s recommended to use a fine mist to avoid saturation.
Additionally, we recommend using a fine mist to avoid saturation and prevent mold growth.
Advanced misting and watering techniques in commercial mushroom growing
In commercial mushroom cultivation, advanced misting and watering techniques are best to achieve optimal growth and yield. These techniques allow growers to control the environmental conditions more precisely, which leads to healthier mushrooms and a higher yield.
Intermittent Misting
One advanced technique is intermittent misting. This involves misting the mushrooms in short bursts, rather than continuously. Intermittent misting mimics the natural environment of mushrooms, and it increases the yield and size of the mushrooms. The frequency of intermittent misting will depend on the type of mushroom being grown and the specific environmental conditions.
Drip Irrigation
Another advanced technique is called drip irrigation. This involves using a system of tubes and valves to deliver water directly to the roots of the mushrooms. Drip irrigation is highly efficient and allows growers to control the amount of water that reaches the mushrooms. This technique also helps to reduce the risk of bacterial or mold growth, as it allows for precise control over the moisture level of the substrate.
Deep Irrigation in Mushroom Growing
A third advanced technique is deep irrigation. This is a method of irrigation where water is applied to the soil at a depth of 6-12 inches below the surface. This method allows the water to reach the roots of the mushrooms more effectively, and it can help to reduce the risk of disease and pests.
It’s also important to keep in mind that different types of mushrooms have different water requirements, so it’s crucial to research the ideal water conditions for the specific type of mushroom you are growing. Additionally, it’s important to monitor the humidity and moisture level of the substrate regularly to ensure that it stays within the ideal range.
