Everything that you need to know about Mushroom tent.

Mushroom tent, those looking to learn Martha tek or the Martha method of Mushroom tent cultivation will find this step-by-step tutorial on setting up and maintaining a Martha tent quite helpful. A troubleshooting guide is included to help you identify potential problems with your growth, along with step-by-step instructions for building a Martha set up and setting up environmental controls.

The Martha Tent is a type of tent manufactured by Martha Tent:

For fruiting mushrooms in trays, blocks, and jars, the name “Martha Tent” was coined by the underground Mushroom tent community. It refers to a medium-sized grow chamber.

In most cases, Martha Tents are small enough to fit in a closet, a kitchen, or a basement. Scaling up from a few ounces to a few kilos of edible or medicinal mushrooms is simple. They can be adapted to meet any area or budget, making their potential unrivaled.

The most reliable way to cultivate magnificent, year-round flushes of mushrooms is with a Martha arrangement. They’re an excellent choice for various species, techniques, areas, and budgets, from novices to advanced Mushroom tent growers.

The following step-by-step guide outlines building and maintaining your own Martha Tent using materials you can find online or at your local hardware or hydroponic store.

Building a Martha Tent: A Step by Step Guide

One of the most efficient methods for growing mushrooms inside is the Martha Tent. There are dozens of Martha Tent builds on Mushroom tent forums, Reddit pages, and Facebook groups, but few are precisely the same. People who grow mushrooms in Martha Tents claim their success in controlling four conditions: humidity, fresh air exchange, temperature, and light.

Humidity and fresh air exchange (for exhausting carbon dioxide) are controlled by Martha Tents, while the environment outside the tent determines temperature and light. Four requirements must be met for your tent’s environmental systems to function.

  •         Dryness: Mushrooms won’t fruit if they’re in a dry environment. Your humidifier and humidity controller provide and monitor humidification to keep the Martha Tent at the optimum humidity level.
  •         Mushrooms, like people, take in oxygen and expel carbon dioxide in the same way. They could be suffocated if the air within the tent isn’t regularly refreshed. Our fresh air exchange blower removes excess carbon dioxide, allowing oxygen to flow freely throughout the tent.
  •         A 55 to 80 degrees Fahrenheit temperature is ideal for most mushrooms to ripen and produce fruit. It is suggested that you set up your tent in a climate-controlled area. When the temperature inside your tent is below 55 degrees Fahrenheit, you may want to use heating pads or warm water humidifiers.
  •         Mushrooms, in contrast to plants, do not photosynthesize. However, efficient fruit development necessitates the presence of ambient light. Your mushrooms will be able to determine where to fruit and the color of their fruit bodies if you place your tent in an area with indirect or additional illumination.


  •         Insect-proof Tent
  •         Fan for Exchanging Refreshing Air
  •         Humidifiers that use ultrasonic waves
  •         A Humidity Regulator
  •         Clamp for a hose
  •         Slightly smaller poly pre-filter
  •         Tray for Dripping


  •         A 4-inch diameter duct
  •         Foaming (cut to fit a window)

Building a Tent Is the First Step

To get started, you’ll need to put together your greenhouse tent. If you don’t have access to a greenhouse tent with five shelves, we recommend moving the bottom shelf to the top. The floor of your tent will need to be reinforced if you decide to do this. ” Our translucent tent was a personal preference, but an opaque stealth tent could also be a viable option for some growers). You can use opaque tents if you add additional illumination at the end of the construction process.)

We prefer to add extra shelf space at the top for a few reasons.

  •         Your tent’s overall grow area can be maximized by using this method
  •         With it, your humidifier has a place to go.
  •         Finally, you’ll have a fresh air exchange fan at the top of the tent, which will help remove humidity and CO2 from the air.

A drip tray should be placed on top of your greenhouse tent once you’ve completed erecting it. This drip tray will aid in the sealing of any leaks and the collection of any extra moisture. If a drip tray is not available, a folded tarp and clamps can be used instead.

Installation of the Humidification System in the Second Step

Next, you’ll need to get your humidification system up and running. An ultrasonic humidifier and a humidity controller are required to monitor and control the Martha Tent’s ambient humidity.

It’s not uncommon for people to ask if I’m producing “magic” mushrooms when I tell them I manage an indoor mushroom farm. My first blog post will focus on the basics of mushrooms and an outline of indoor commercial mushroom production.

What Is a Mushroom?

Mold, yeast, and mushrooms are all part of the fungal kingdom, including fungi. When it comes to fungi, the mycelium (the fungus’s vegetative structure) is mycelium.

Nutrient intake and breakdown are carried out by the mycelium’s network of white filaments, referred to as hyphae. The mycelium is like a fruit tree’s roots, trunk, branches, and leaves, while the mushroom is the fruit and the spores are the seeds. Mushrooms can be divided into three primary categories.

Saprophytes are the first. Soil and carbon cycling are aided by these mushrooms’ breakdown of organic material. The parasitic fungus obtains nutrients from live creatures by infecting them. Lastly, mycorrhizae fungi work with plant roots to transport nutrients, fix nitrogen, and transmit chemical signals.

These are fascinating mushrooms since they might take decades to establish themselves, making cultivation extremely challenging. The way trees in Canadian forests connect described in an excellent TedTalk on mycorrhizae.

As they develop and mature, mushrooms exude spores. These spores facilitate the organism’s reproduction. Mushrooms can reproduce sexually or asexually (with themselves). Hundreds of millions of mushroom spores are emitted at a time.

Cultivation of Mushrooms Indoors

Whether you want to grow mushrooms for pleasure or profit, you can find a method to get started, and it isn’t as difficult as you would think. Hobbyists prefer hydroponic tents and logs. Compared to indoor growth on blocks, logs are simple and have minimal maintenance, but they can take longer to bear fruit. Using a hydroponic tent, you may grow all year round in the comfort of your own home. Commercial manufacturing necessitates far more, and I’ll now go over some of those requirements.

Commercial Mushroom tent production frequently includes all stages of the mushroom life cycle, from growing to composting, on a larger scale. Agar, a nutrient-rich substrate, is commonly used by growers to cultivate their own mushroom cultures on Petri dishes, allowing rapid mycelial growth.

It is possible to move the growing culture onto a larger substrate to keep the mycelium “running,” which is often a grain. We call this the spawn. Cultivators will need to acquire, mix, and sterilize bulk substrate as this expands and grows. Soybean hulls, 50 percent hardwood sawdust/fuel pellets, and 60 percent water are popular substrate mixtures. Earth Angel Mushrooms’ T.R. Davis created it.

His YouTube channel is a goldmine of information, so make sure to check it out. Autoclave bags with microporous filter patches, then package the substrate mixture. Many information and rules must be followed when conducting this lab work, even if it appears simple. Paul Stamets’ book, Growing Gourmet and Medicinal Mushrooms, is a fantastic place to start.

All bacteria and fungi are killed by putting the bags in a sterilizer such as a steam sterilizer, an autoclave, or a pressure cooker. Mushroom spawn is then utilized to inoculate the substrate when the bags have cooled.

The bags are placed in a chamber where they are let to colonize the substrate until they are ready to ripen. Bags of mushrooms are carried into the growing area at this point. Isn’t that simple, right?

To put it another way,

The rooms/separate places needed for each step are briefly described below. A place for storing and mixing ingredients is required. It’s fine that this area isn’t spotless since it will not be. In addition to storing numerous supplies, this area is used to mix and bag all raw materials. Auto baggers are prevalent in large commercial businesses, but if you’re starting, you may get away with utilizing a large tote or bucket and filling the bags by hand. When sewing bags, you’ll go through a lot of water, so make sure it’s close at hand.

 The Laboratory

On to the science. As a result, the lab will be the most hygienic place in the entire organization. A laminar flow hood is typically used for lab activities, agar plates, spawn production, and substrate inoculation. It is essentially a fan pushing air through an electrostatic HEPA filtration system. All work in front of the flow hood is protected from airborne particles, ensuring a low danger of contamination. Filtered air is generally used to provide positive pressure in these areas.

There is an incubator room here.

The incubation room is located in the adjacent space. There’s a lot of mycelium in this area. All of these rooms must be able to maintain an even temperature. Temperatures typically range from the low 70s to the upper 70s. However, this varies amongst species. Non-porous walls that won’t harbor bacteria or mold should be used in this space, and those that are easy to clean regularly.


Describe the Martha tent to me.

For fruiting Mushroom tent in trays, blocks, and jars, the name “Martha Tent” was coined by the underground Mushroom tent community. It refers to a medium-sized grow chamber. In most cases, Martha Tents are small enough to fit in a closet, a kitchen, or a basement.

When it comes to a Mushroom tent growing chamber, what do you need?

Grow chambers can range from 50 to 70 degrees Fahrenheit, with an 80 to 99 percent humidity level, depending on the Mushroom tent growing. A floor drain, a hard, non-porous floor, and walls that are easy to clean and won’t absorb water are necessities for any grow room.
