What You'll Learn
Yield varies from 2-3 grams to 7 grams per cake, per flush
The yield from BRF cakes varies depending on several factors, including the density of the cake, RH, FAE, and temperature. It is also important to use the correct containers for BRF cakes, such as short and wide mason jars, to prevent stalling during colonization and to ensure easy removal from the fruiting chamber.
While some sources claim that yields of 15-20 grams of dried mushrooms per cake are possible, others suggest that this is unlikely, and that a more realistic yield is around 5-7 grams per cake. This is supported by reports from cultivators who have achieved yields of 7 grams of dried mushrooms from one cake under optimal conditions, including good air exchange.
For beginners, it is important to manage expectations, as initial yields may be lower. One cultivator reported yields of 2-3 grams per cake per flush, with later grows producing better results. Another cultivator reported yields of around 40 grams of dried mushrooms from six BRF cakes.
To increase yields, some cultivators recommend using gypsum, which can result in yields of 5-6 grams per flush. Additionally, proper sterilization of the substrate and fruiting chamber is crucial to reducing contamination and improving yields.

Dry yield per flush can be up to 8 grams
The dry yield per flush from one BRF cake can be up to 8 grams. However, this yield is dependent on several factors, including the density of the cake, RH, FAE, and temperature. The container used for the BRF cake is also important, with wider mason jars being more suitable than taller, narrow ones. Additionally, a pressure cooker is recommended to decrease the chances of contamination.
While BRF cakes are a popular starting point for mycologists due to their affordability and ease of use, they may not produce as much fruit as other methods. It is important to follow the Tek method and maintain proper sterilization and air exchange for optimal yields. With experience, cultivators can experiment with different techniques to improve their yields.
The yield from BRF cakes can vary, and some sources suggest that a dry yield of 5-7 grams per 1/2 pint cake is more realistic. This can be influenced by the number of flushes, with the first flush typically yielding less than subsequent ones. Additionally, the type of flour used can impact the yield, with rye flour being a cost-effective alternative to brown rice flour.
Overall, while it is possible to achieve a dry yield of up to 8 grams per flush from one BRF cake, there are many variables that can impact the final yield. Proper research, patience, and experimentation are key to achieving optimal yields when cultivating mushrooms using BRF cakes.

A good yield from a 1/2 pint is 7 grams
When it comes to cultivating mushrooms, yields can vary depending on various factors such as the substrate used, the species of mushroom, and environmental conditions. In the context of a 1/2 pint of BRF cake, a yield of 7 grams of dried mushrooms can be considered a good outcome.
BRF, or brown rice flour, is a commonly used substrate for mushroom cultivation due to its nutritional content and ability to retain moisture. It provides an ideal environment for mycelium growth and subsequent mushroom fruiting. The yield from a 1/2 pint BRF cake can vary depending on the species of mushroom and other factors, but 7 grams of dried mushrooms is certainly a respectable outcome.
To maximize yields, it is important to follow sterile techniques during the preparation and inoculation of the BRF cake. Contamination by competing microorganisms can hinder mycelium growth and reduce the potential yield. Proper incubation conditions, including maintaining optimal temperature and humidity levels, are also crucial for successful mushroom cultivation.
Additionally, the species of mushroom plays a role in determining the yield. Some species are naturally more prolific fruiters than others. Selecting a mushroom variety known for its vigorous fruiting capabilities can increase the likelihood of achieving higher yields.
While 7 grams may not seem like a significant amount, it's important to consider the concentration and potency of dried mushrooms. Dried mushrooms are more potent than their fresh counterparts because the drying process concentrates the active compounds. As such, a smaller amount of dried mushrooms can provide similar effects to a larger quantity of fresh mushrooms.
In conclusion, achieving 7 grams of dried mushrooms from a 1/2 pint BRF cake is a satisfactory outcome. By maintaining sterile techniques, providing optimal environmental conditions, and selecting appropriate mushroom species, cultivators can maximize their yields and consistently reach, or even surpass, this benchmark.

6 BRF cakes yielded 40g dried
Yield can vary depending on a number of factors, including the type of mushroom being cultivated, the substrate used, and environmental conditions. With that said, it is certainly possible to end up with 40 grams of dried mushrooms from six BRF cakes. In fact, this would be a fairly typical yield for certain strains of mushrooms, particularly those that are known for their relatively small size, such as Psilocybe cubensis.
It's important to note that the drying process significantly reduces the weight of mushrooms. Fresh mushrooms typically contain a large amount of water, which is removed during the drying process, resulting in a much lower final weight. Therefore, it is common for a relatively large number of fresh mushrooms to yield a smaller amount of dried product.
The yield from six BRF cakes can also be influenced by the cultivation technique used. For example, using a monotub setup or a grow tent with controlled environmental conditions can potentially increase the yield compared to a simpler setup. Additionally, the experience and skill of the cultivator can play a role in maximizing the yield.
While 40 grams of dried mushrooms from six BRF cakes is not an exceptionally high yield, it can still provide a reasonable number of servings, depending on the dosage preferred by the individual. For instance, with a typical dose of 1 to 2 grams, 40 grams could furnish 20 to 40 individual servings.
In conclusion, while the yield of 40 grams of dried mushrooms from six BRF cakes may seem modest, it is not uncommon, especially for certain mushroom strains. By optimizing cultivation techniques and environmental conditions, it may be possible to increase the yield in future attempts.

Yields can be improved by using a pressure cooker
The yield from one BRF cake can vary from 2-3 grams to 6-8 ounces (170-227 grams) of dried mushrooms per flush. The yield depends on various factors, including the number of flushes, the type of BRF cake, and the growing conditions.
Now, let's discuss how yields can be improved by using a pressure cooker.
A pressure cooker is an essential tool for mushroom cultivation, especially when using BRF cakes. While not mandatory, it greatly improves the chances of a successful grow by reducing the risk of contamination.
Contamination by bacteria, fungi, or other microorganisms is a significant concern in mushroom cultivation. These contaminants can outcompete the desired mycelium, leading to a failed crop. Pressure cookers create a hostile environment for these contaminants by generating a combination of high heat and pressure, killing even the most resilient endospores.
When choosing a pressure cooker, consider the following factors:
- Capacity: Select a cooker with ample capacity, accommodating multiple jars or bags. The Presto 23-quart pressure cooker, for example, can hold up to 26 half-pint jars, making it a popular choice for mid-to-large-scale growers.
- Durability: Sterilization is a frequent process, so opt for a durable cooker that can withstand repeated use. The All-American 925, for instance, is known for its robust build and performance but comes at a higher price point.
- Performance: Ensure your cooker can consistently reach and maintain the required PSI for sterilization, typically around 15 PSI for mushroom cultivation.
- Maintenance: Proper care and maintenance are crucial to extending the lifespan of your pressure cooker. Clean and dry it after each use, and refer to the manual for specific care instructions and troubleshooting.
By investing in a quality pressure cooker and maintaining it well, you can significantly improve your yields by reducing contamination and providing your mycelium with a clean, uncontaminated environment to thrive.
