The ideal temperature and humidity levels inside a mushroom grow chamber can vary depending on the species of mushroom being cultivated. However, here are some general guidelines:
Temperature:
• For most common mushroom species like button mushrooms (Agaricus bisporus), oyster mushrooms (Pleurotus spp.), and shiitake mushrooms (Lentinula edodes), the ideal temperature range for fruiting is around 55-75°F (13-24°C).
• Different stages of growth may require slightly different temperatures. For example, the colonization stage (mycelial growth) typically prefers slightly warmer temperatures, around 70-75°F (21-24°C), while the fruiting stage may prefer slightly cooler temperatures, around 55-70°F (13-21°C).
Humidity:
• Mushrooms require high humidity levels to thrive, typically ranging from 80% to 95% relative humidity (RH) during the fruiting stage.
• Maintaining high humidity is critical to prevent the mushrooms from drying out and to promote healthy fruiting and sporulation.
To achieve and maintain these conditions, mushroom growers often use various methods and equipment such as:
• Humidifiers or misting systems to increase humidity levels.
• Ventilation systems to regulate airflow and prevent the buildup of excessive moisture.
• Thermometers and hygrometers to monitor temperature and humidity levels inside the grow chamber.
• Insulation and sealing to prevent temperature fluctuations and maintain stable conditions.

Setting up and modifying a Martha tent or Monotub (Monochamber) for optimal mushroom growth involves creating an environment that provides the right conditions for your specific mushroom species. Here's a step-by-step guide:
Selecting the Container: Choose a Martha tent or Monotub that suits the scale of your mushroom cultivation project. Martha tents are often used for smaller-scale operations, while Monotubs are suitable for larger-scale production.
Prepare the Container: Clean the container thoroughly to ensure it's free from any contaminants. We recommend isopropyl alcohol wipes, or a 70% isopropyl alcohol and water blend in a spray bottle. The alcohol will evaporate and leave no residues after it has dried. Effectant disinfectant is another option for mushroom safe sanitization.
Substrate Preparation: Prepare your substrate according to the requirements of your chosen mushroom species. This may involve pasteurizing or sterilizing the substrate material, such as straw, sawdust, or a commercial mushroom substrate mix.
Inoculation: Inoculate the substrate with mushroom spawn. This can be done by mixing the spawn into the substrate material thoroughly.
Incubation: Place the inoculated substrate in a warm, dark location for the mycelium to colonize the substrate. Maintain the temperature within the optimal range for mycelial growth, usually around 70-75°F (21-24°C). A hygrometer is the best way to monitor temperature and humidity.
Fruiting Conditions:
• Once the substrate is fully colonized with mycelium, it's time to initiate fruiting conditions. Transfer the substrate to the Martha tent or Monotub.
• Adjust the temperature inside the tent or tub to the optimal range for fruiting, typically around 55-75°F (13-24°C), depending on the mushroom species.
• Increase humidity levels inside the tent or tub to 80-95% relative humidity. This can be achieved by using a humidifier or misting system.
• Provide adequate airflow to prevent the buildup of carbon dioxide and promote healthy mushroom growth. Ventilation fans or holes can be added to achieve proper airflow.
• Lighting: Some mushroom species benefit from light exposure during the fruiting stage. If necessary, provide indirect light to the mushrooms using fluorescent or LED lights on a 12-hour light cycle.
Monitoring and Maintenance: Regularly monitor the temperature, humidity, and airflow inside the Martha tent or Monotub. Make adjustments as needed to maintain optimal conditions. Check for signs of contamination and remove any contaminated material promptly.
By following these steps and carefully managing the environmental conditions inside the Martha tent or Monotub, you can create an optimal growing environment for your mushrooms and maximize your yields.
The suitability of lighting systems for mushroom grow chambers depends on the specific requirements of the mushroom species being cultivated and whether light exposure is necessary for fruiting. Here are some types of lighting systems commonly used in mushroom cultivation:
Fluorescent Lights: Fluorescent tubes are commonly used in mushroom grow chambers because they emit a balanced spectrum of light that is suitable for most mushrooms. They are energy-efficient and produce low heat, making them ideal for maintaining consistent temperatures inside the grow chamber.
LED Grow Lights: LED grow lights are increasingly popular in mushroom cultivation due to their energy efficiency and customizable spectrum options. They can be adjusted to provide specific wavelengths of light tailored to the needs of different mushroom species.
Incandescent Bulbs: Incandescent bulbs are less commonly used in mushroom cultivation because they produce more heat and consume more energy compared to fluorescent and LED lights. However, they can still be used if heat output is not a concern and if they provide the necessary light spectrum.
Natural Light: Some mushroom species benefit from exposure to natural sunlight during the fruiting stage. If your grow chamber is located in an area with access to natural light, you can position it near a window or use skylights to provide indirect sunlight to the mushrooms.
When positioning lighting systems in a mushroom grow chamber, consider the following guidelines:
• Even Distribution: Position the lights to ensure uniform coverage of the entire growing area. This helps promote even growth and prevents uneven fruiting.
• Adjustable Height: If possible, install the lights at an adjustable height so you can control the distance between the lights and the mushroom substrate. This allows you to optimize light intensity for the specific needs of your mushrooms. Ratchet hangers work the best for this purpose.
• Avoid Direct Contact: Avoid placing the lights too close to the mushroom substrate to prevent overheating and damage to the mushrooms. Maintain a safe distance to ensure proper air circulation and to minimize the risk of heat stress.
• Light Cycle: If using artificial lighting, provide a consistent light cycle of 12 hours of light followed by 12 hours of darkness during the fruiting stage. This helps mimic natural daylight cycles and promotes healthy fruiting. A digital timer will help you keep on track.
By selecting the appropriate lighting system and positioning it correctly within the grow chamber, you can provide the necessary light exposure for your mushrooms to thrive and maximize your yields.
The frequency and amount of misting or watering required for mushrooms inside a grow chamber depend on several factors, including the type of mushroom, the substrate used, the stage of growth, and the environmental conditions inside the chamber. Here are some general guidelines:
