How to Make a Martha Tent Mushroom Fruiting Chamber (2024)

FAQs

Should the humidifier be on top or bottom of Martha tent? ›

The ultrasonic humidifier will be placed at the bottom of the tent, with the electrical wires threaded underneath the bottom of the greenhouse plastic. Make sure that any electrical component is not sitting in the drip tray where it is more likely to have direct contact with water.

You don't need to have the fan in your Martha Tent running every minute of the day. Use either a simple timer or a CO2 controller to tell your extraction fan when it should turn on and off. If you're using a timer, you'll need to experiment and find the right balance depending on your fan size and air output.

Button mushrooms, temperature of 75-77 degrees Fahrenheit for mycelium growth then once the mycelium is fully formed temperature range should be 53-60 degrees & 90% for air humidity level. For straw mushrooms it's 95 degrees wherein growth can occur between 59-113.

The most comfortable level to set your humidistat is between about 35 and 55 percent relative humidity. This is the range when bacteria and viruses can't live as long and annoying static shock is minimized.

As a general principle, the higher, the better. The mist that the humidifier produces needs to mix in with the surroundings to ensure proper air circulation. If you place it on the floor, the mist will remain too low to the ground and only cause wet floors.

As a reminder, monotubs are single chambers for growing top-fruiting mushroom species from substrate beds or housing fruiting blocks, while grow tents, also known as Martha tents, are designed for housing fruiting blocks or trays, or multiple methods at once, inside a larger environmentally-controlled chamber.

a. Add humidity to the growing environment by spraying the sides and up into the hood of the bag several times over the course of a few hours, this will give the added moisture time to be absorbed rather than pooling at the bottom. b. Close the bag up by tilting the hood down around the bottom of the bag.

Install an exhaust fan and a filter: Cut a hole on top of your tent for the exhaust fan. This helps remove CO2, as mushrooms produce CO2 and consume oxygen. Ensure the filter is positioned where fresh air enters the tent.

The Ultrasonic Humidifier: The Best Humidifier Type For Growing Mushrooms. If you really want to see success growing mushrooms, you are bet to get an ultrasonic humidifier. These humidifiers work using spinning discs that vaporize water droplets – which are then pumped out of the unit and into your room.

The humidity with a fruiting chamber must remain high in order to encourage pinning and to all the growing mycelium to retain as much water as it can hold. The relative humidity(RH) of the air around fruiting mycelium should be at least 90%.

Does a mushroom fruiting chamber need light? ›

Mushrooms usually live in the undergrowth and need light that is not too intense but not absent either. Mushroom fruiting chambers have lighting systems that can accurately simulate the optimal sun exposure that mushrooms receive in their natural environment.

The best location for your humidifier is near the air intake area of your grow tent, allowing the humidified air to be evenly distributed throughout the space as fresh air circulates in.

Locate them near the bed but at least two feet from the floor and each wall and at least five feet from the ceiling.

Look for a flat, sturdy, raised surface, such as a table or nightstand. Placing your humidifier a few feet off the ground gives the mist more time to mix with the air before settling on the floor.

So, in a home, humid air rises up, not down.
