Mushroom cakes are a great way to grow your own mushrooms at home. One of the most basic techniques for growing mushrooms is PF Tek, which can be used to grow a wide variety of mushrooms, including Shaggy Mane, Lion's Mane, and P. Cubensis. PF Tek involves using a pressure cooker, organic brown rice flour, vermiculite, perlite, and canning jars. After birthing the cake, it is recommended to soak it in water for about 24 hours and then roll it in dry vermiculite. To maximize the fruiting area, some people suggest cutting the cake in half to increase the surface area in contact with the vermiculite, which may result in more but smaller mushrooms. To fruit the cakes, they should be placed in a fruiting chamber with moist perlite and cased with dry vermiculite for a higher yield. The cakes should be misted at least three times a day or whenever they look dry, and the air inside the fruiting tank should be exchanged at least once a day by opening the lid and fanning for 30-60 seconds. Maintaining optimal humidity and temperature levels is crucial for successful mushroom growth.

What You'll Learn
Soak the cake in water for 24 hours
Soaking your mushroom cakes in water for 24 hours is a common practice for those growing their own mushrooms. This process is known as rehydration, which is essential for triggering a new flush of mushroom growth.
Firstly, rinse your mushroom cake under running water before rehydration. Place the cake into a plastic container, ensuring it is large enough to be convenient for this process. You can use tap water or clean drinking water for this step.
Fill the container with water and completely submerge the cake. You may need to place a weight or a jar of water on top of the cake to ensure it is fully submerged. Leave the cake to soak for 24 hours.
Some growers suggest that temperature shocking the fungus by soaking it in the refrigerator causes the fruits to appear quicker than a room-temperature soak. However, this introduces more risk of contamination.
After the 24-hour soak, some growers roll the cakes in dry vermiculite. This process can be repeated between flushes to rehydrate the cakes, and the cakes should last for about 3-4 flushes.

Maintain temperature and humidity
Maintaining the right temperature and humidity is crucial for successful mushroom fruiting. Mushrooms require a specific temperature range, adequate humidity, and good ventilation to grow optimally.
To control the temperature, you can use a thermometer or temperature sensor to monitor the temperature in your growing environment. The ideal temperature range for mushroom growth is typically between 60-75 °F (18-24 °C), depending on the mushroom species and growth stage. You can adjust the temperature using heating pads or cooling fans to maintain the desired range.
Now, let's talk about humidity. Mushrooms require high humidity levels, usually around 85-95% relative humidity, to initiate primordia formation and support their growth to maturity. You can control humidity by using misting spray bottles, pond misters, or fans. Misting the growing area and mushrooms with a fine mist of water several times a day is a simple and cost-effective way to increase humidity. However, this method may not be sufficient for large-scale cultivation due to the manual labour involved and the challenge of maintaining consistent humidity levels.
Additionally, good air circulation is crucial for maintaining optimal humidity levels. You can achieve this by using fans or ensuring proper ventilation in your growing space. It is important to note that high temperatures can cause humidity levels to drop, so maintaining the right temperature range is essential for stable humidity.
Finally, while maintaining high humidity is crucial, excessive humidity above the recommended range can lead to the growth of mould and other harmful microorganisms. Therefore, it is important to monitor humidity levels closely and make adjustments as needed to create the perfect environment for your mushrooms to thrive.

Use a fruiting chamber
A fruiting chamber is an essential component of the mushroom-growing process. It provides the optimal environment for mushrooms to grow and flourish. Here are some detailed instructions on how to use a fruiting chamber to fruit mushroom cakes successfully:
Building the Fruiting Chamber
Construct a "shotgun" fruiting chamber using a clear plastic tub. Drill 1/4" holes in a 2" x 2" grid pattern on all six sides of the tub. This design allows for maximum ventilation, which is crucial for mushroom growth. Place about 5" of damp perlite at the bottom of the tub, and raise it slightly at the corners using mason jars, soup cans, wood blocks, or bricks. The perlite provides a moist base and helps regulate humidity.
Preparing the Mushroom Cakes
After the cakes have fully colonized, birth them by wearing gloves and gently turning the jar upside down. The cake should slide out easily. Rest the cakes on the lids of wet vermiculite, arranging them on top of the perlite. Vermiculite protects against contamination and provides additional nourishment to the cakes.
Maintaining the Fruiting Chamber
Maintain the fruiting chamber by regularly misting the cakes and exchanging the air inside the chamber. Mist the cakes at least three times a day or whenever they appear dry. To exchange the air, open the lid and fan over the top for 30-60 seconds. Then, spritz the shield with fresh mist and seal the chamber again. Maintain a humidity level between 90-99% and a temperature between 70F and 80F for optimal mushroom growth.
Harvesting the Mushrooms
Fruiting should begin within 3-5 days of birthing the cakes. Keep a close eye on the mushrooms as they approach harvest time. The veil under the mushroom cap is delicate and drops quickly. Harvest the mushrooms just before or soon after the veil detaches, as this is when the spores begin to fall. Pluck the mushrooms carefully from the mycelium loaf by hand.

Harvesting techniques
Harvesting mushrooms from cakes requires patience and diligence. Here are some detailed techniques to help you successfully fruit mushroom cakes and harvest a bountiful crop:
Preparation
Before placing the cakes in the tank, mist the inside of the tank and the jar lids with water. Turn the jar upside down, wearing gloves, and gently tap to birth the cake into your hand. Place the cakes on the lids of wet vermiculite, arranging them carefully in the bottom of the tank.
Maintaining Conditions
Maintain the temperature between 70F and 80F for optimal growth. Mushrooms thrive in temperatures above 80F, which speeds up fruiting. Ensure the humidity level stays within the optimum range of 90-99%. An easy way to gauge humidity is to check for condensation on the surfaces inside the tank.
Air Circulation
Exchange the air inside the tank at least once a day. Mushrooms emit CO2 as they grow, so introducing fresh air is crucial. Open the lid and fan over the top for 30-60 seconds. Mist the shield and seal the tank. Repeat this process at least three times a day for best results.
Harvesting
Keep a close eye on the mushrooms as they approach harvest time. The veil beneath the cap is delicate and drops quickly, releasing spores. Harvest the mushrooms by carefully plucking them from the mycelium loaf when the veil is still intact. If you plan on consuming the mushrooms soon, simply pick them by hand, breaking them off at the base.
Increasing Yield
To increase the yield, you can cut the cakes in half to create more surface area for mushrooms to grow. However, this may result in smaller mushrooms. Another technique is to use a casing, which provides structure and a steady water supply, allowing the mycelium to form a network. While this method is more challenging and prone to contamination, it can result in a larger harvest.
By following these techniques and maintaining the optimal conditions, you can successfully fruit mushroom cakes and harvest a plentiful crop.
