In this article, we will show you how to make a mushroom grow tent. This is a great project for those who want to cultivate their own food and mushrooms in an environmentally friendly way. We have all the steps outlined below so that it is easy to follow along!

What Conditions are Necessary to Grow Mushrooms Inside the Home?

Mushrooms require a humid environment with plenty of oxygen. This means that they need enough space in which they can breathe and be kept away from direct sunlight or heat lamps, neither of which is good for them. They also do not like it when there is too much airflow around their mycelium (the vegetative part of the fungus) while it grows into fungal threads called hyphae. The substrate should remain moist but never soggy– this will rot your fungi and cause problems! If you’re using straw as a growing medium then you’ll want to keep an eye on how wet things get so that mold doesn’t form. A simple way to achieve this is to use a spray bottle and mist things often. If you’re growing in an enclosed container like a plastic tub, make sure that the lid fits tightly so there isn’t any airflow from outside of it or too much humidity will accumulate inside (mold!)

How Long Before the Mushrooms Begin to Bear Fruit?

Once you have your mushrooms in the jar, it will take about a week for them to grow. After they are grown, you can leave them there and harvest them when ready. To speed up the growing time, you can place them in a dark and humid room.

List of Materials for Creating a Mushroom Grow Tent

A grow tent is a great way to keep your mushroom spawn protected from the elements. A room in which to set up a tent for hydroponics can be as simple as an empty closet or you may want something more elaborate with additional shelves and lights. Once you have determined where you are going to put it, purchase some plastic or wire shelves for storing bags of caviar. You will also need LED strips, fans for ventilation, glass jars, bags of mushroom spawn (or mycelium), spores for inoculating the bags of spawn, and hydrogen peroxide (H₂O₂) or bleach to sterilize surfaces and tools.

Building a Mushroom Grow Tent

Mushrooms require a humid environment in order to grow. To achieve this, you will need to construct your own mushroom growing tent that can be reused for many different harvests of mushrooms. Mushroom tents are typically constructed out of opaque materials so the light does not damage the inside mycelium, which would interfere with future growths. It’s important to remember that when using any type of fabric or mesh material around fungi it is necessary to have proper ventilation and avoid trapping humidity within.


The first step is to humidify the tent by using a spray bottle. Fill it with filtered water and then spritz all of the surfaces inside of your mushroom grow tent, including corners that are hard to reach. It’s important that you don’t use too much moisture in order not to drown out any future harvests! The humidity level should be around 90% for most species of fungi but can vary depending on what kind you’re growing or where they naturally occur.

Fresh Air Exchange

The next step is to perform fresh air exchanges. This means that you’ll need to ensure the tent has enough ventilation for carbon dioxide (CO₂) levels and humidity levels to be optimal for your fungi’s growth. It may take some practice but what works best will depend on environmental conditions including temperature, light exposure, drafts, etc.


You’ll also want to make sure that your fungi are getting at least 12 hours of light per day. If you’re growing indoors, this should be relatively simple unless there is a window nearby or another source of natural lighting–in which case the use of artificial lighting may even out the discrepancy in time.

Fresh Air Intakes

To make sure that your fungi are getting enough CO₂, you’ll need to leave a small opening between the zipper and tent wall (or some other form of venting system). Make this as small as possible so that there is no risk of insects or contaminants entering.

Your fungi will also be producing water vapor; if this isn’t removed from the growing area it can cause humidity issues. If you’re using an automatic humidifier then you probably won’t have any problems but if not then feel free to use an exhaust fan to remove undesirable moisture and heat buildup. Just don’t let air escape through openings in the grow room!

Remember: having too much ventilation can lead to rapid evaporation–which means lower humidity levels.
