4 Ways On How To Create Humidity In A Small Greenhouse For Mushrooms

If you’re wondering how to create humidity in a small greenhouse for mushroom, the best way is to have humidifiers. Yes, you read it right; you might need humidifiers to provide the ideal humidity for mushrooms grown in a small greenhouse.

Mushrooms do not contain chlorophyll, allowing it to survive without needing sunlight, unlike most plants. But of course, it does need certain factors to survive. The ideal light, water, and heat will aid the growth of your mushrooms. Therefore, you must consider these factors for you to have a good yield.

Creating Humidity In A Small Greenhouse For Mushroom

Let me ask you something, is your skin dry? If so, you’d apply moisturizer to bring back the hydration unto your skin. But did you know mushrooms are somewhat like that? Mushrooms require an adequate amount of moisture to avoid water loss. 

Well, here are the ways on how to create humidity in a small greenhouse for mushroom:


#1 Humidifiers for creating humidity for mushroom

As I have mentioned earlier in this article, humidifiers will help you with this one. Since there are different kinds of humidifiers, we’ll understand how each of these can help.


By using wicking humidifiers

This kind of humidifier draws off moisture from the water in the reservoir all over a large area. It then evaporates the water with the help of a fan, increasing the humidity in the growing area of the mushroom.

However, this type of humidifier might be suitable for mushrooms that only need a smaller relative humidity percentage. Since wicking humidifiers cannot raise the relative humidity by up to 85%; because most types of mushrooms require an RH of at least 90% when fruiting.


By opting for an ultrasonic humidifier

This type of humidifier is best for growing mushrooms. Ultrasonic mushrooms have a spinning disc responsible for vaporizing water droplets. The number of discs would determine the amount of humidity it can produce.

The ultrasonic humidifier will then pump out vaporized water droplets all over the growing area. It is the best humidifier for growing mushrooms as it raises the relative humidity to 100%.

Most mushroom growers would place humidifiers inside the fruiting area, but you can also put it outside your chamber and pumped in. Pumping in humidity would be beneficial as it also brings in the fresh air, reducing CO2 levels resulting in better fruit.

Moreover, we suggest you’d choose an ultrasonic humidifier with an on/ timer to avoid too much water pumped out of the unit that could drown your mushrooms or create wet spots. The humidifier is ideal for a 4×8 to grow room and even 4 tier greenhouse set up.


By placing a multidisc floating ultrasonic humidifier 

By its name, this humidifier has multiple discs that float on the top of the water. Just place the float in a bucket of water and point a fan to the bucket. 

The multidisc floating ultrasonic humidifier is incredible as it can put the area at the right humid level in just for a few minutes or hours.

Just a reminder- it’s a must always to change the water when using this type of humidifier. By that, you can avoid moulds and bacteria from growing in the substrate, so you’re sure of the quality of your yield.

Additionally, you can place the fan outside the growing area to avoid damage due to the humidity of the place. Also, you can change the disc when it burns out because of too much use. 


#2 Spray water to keep the humidity

Indeed, all these types of humidifiers are great for your mushroom. It will provide the humidity you need. However, if you want a simple way to create humidity, then a spray bottle would be enough for a 4 tier greenhouse. 

Spray water to the walls of your chamber and fan that lets in the fresh air. You have to be diligent as you need to mist many times a day to maintain the humidity inside the greenhouse where your mushroom grows. 

Avoid spraying directly to the substrate of your mushroom since it could damage it. Hanging a wet sheet will also help in creating a humid environment for the mushroom to strive.

Maintaining the humidity is very important in a small greenhouse since mushrooms stop growing during the dry season. Be mindful of how much water you are giving as it could drown and damage your mushrooms.


#3 Consider proper lighting

Now that you know how to create humidity for your mini greenhouse, you’d want to consider the light inside if it is suitable for the mushrooms you are trying to grow.

Mushrooms are a fungus that dwells in almost any place as long as it’s moist. Again, a mushroom does not need any sunlight, so you might want the small greenhouse to be as dark as possible.

However, it doesn’t mean they don’t need any light at all. Mushrooms found in the wild often grow in shady areas and wooded areas where they can receive some light. A dim light such as a fluorescent light would be enough for your mushroom, but only for a few hours. 

Remember, if you want to create the right humidity for your mushroom, consider proper lighting.


#4 Keep the right temperature

Moving on to temperature, 70°F would be ideal for mushrooms. However, commercially grown mushrooms require a temperature of 55°F and not more than 60°F to yield much fruit.  

Wild mushrooms are different from the commercially grown mushroom in terms of environment and how it is grown. Mushrooms that grow in the wild would feed off from dead trees and even decaying animals, making it dangerous to consume. 

In contrast, commercially grown mushrooms are safe to eat since growers make sure that all the elements involved for its growth are well-controlled. So, if you want to want to create humidity for your small greenhouse, then know the right temperature the mushroom can properly grow.



We hope that this article helped you understand how to create humidity in a small greenhouse for mushroom; as well as other factors that are suitable for the growth of your mushroom too. Thank you for reading, and have a good day!

Division is an excellent way to grow Mexican heather and also keep the plants from overcrowding an area. Gently loosen the soil around a plant to make lifting easier and divide the root ball into sections using a sharp and sterile knife. Depending on its size, you can get up to four divisions for transplanting in containers or onto the garden.

Water and fertilizer

While Mexican heather can tolerate dry conditions, it would still be optimal to keep them well-hydrated. You can water the plants deeply once per week, but ensure that you’re using a well-draining medium and container. Then, wait for the ground to dry in between waterings to avoid creating standing water. 

Remember to adjust the frequency and amount of water you give to the plants. More so, container Mexican heather plants would dry faster, so water them often. You can also mulch every spring to maintain soil moisture and even smother weeds.
