B+ Mushrooms (P. Cubensis) | Strain & Cultivation Guide

Are you curious about B+ mushrooms and their unique effects? Look no further! B+ mushrooms (P. Cubensis) are a beloved strain in the world of psychedelic mushrooms, known for their monstrous size and potent, long-lasting effects. But what makes B+ mushrooms so special? In this popular article, we'll cover literally everything you need to know about the B+ strain of Psilocybe Cubensis, including cultivation techniques for people in legal jurisdictions. For people in the US, cultivation is 100% illegal and should not be attempted, and this post is for educational value only. Our B+ spores should only be used for microscopy & taxonomy, and not cultivation.  

B+ Mushrooms

Background Of The B+ Mushroom

History of B+

The B+ mushroom, or Psilocybe Cubensis B+, is a highly sought-after strain of psychedelic mushroom with a fascinating history. While most of the popular P. Cubensis strains are believed to have originated in the subtropical regions of Mexico and Central America, this one is said to have been discovered growing in Florida, where it was found standing over 16 inches tall. This impressive size, combined with its unique characteristics and potent effects, quickly made B+ mushrooms a popular choice among psychonauts and cultivators alike. More recently, discoveries by Eden Shrooms' lead mycologist suggest that this strain is cold resistant, quick-to-colonize, and is one of the easier P. Cubensis strains to work with. 

Identification & Physical Traits

Identifying B+ mushrooms is relatively easy, as they have a few distinct physical characteristics. One of the most noticeable traits of the B+ strain is its large, caramel-colored caps that can reach up to five inches in diameter when fully matured. The caps are also slightly curved, with a distinct "nipple" in the center and occasional spotting on the top, giving them their unique appearance. Additionally, the stems of B+ mushrooms are wide and dense, often measuring up to six inches long and one inch thick. The stems typically have a white or off-white color and can develop a bluish hue when bruised or damaged. Overall, the combination of large caps and thick stems makes the B+ strain easy to identify among other species of psilocybin mushrooms.

Natural Habitat

As a strain of Psilocybe cubensis, the natural habitat of B+ mushrooms is typically warm, humid climates, such as those found in Mexico, Central and South America, and, in this case, the southeastern United States. They can often be found growing in grassy fields, on decomposing plant material, and in cow pastures. B+ mushrooms are known to thrive in subtropical regions with frequent rainfall and warm temperatures, and they can grow in a variety of soil types. In nature, the growth cycle of B+ mushrooms is triggered by warm temperatures and a sudden increase in humidity, which can occur after a period of rain or heavy fog. However, with the proper conditions and equipment, B+ mushrooms can also be cultivated indoors, making them a popular choice among home cultivators.

While there are some subtle differences, you can pretty much use the natural habitat of all P. Cubensis strains as the benchmark here.

Uses & Effects

How to Enjoy B+ Mushrooms

There are many ways to consume B+ mushrooms, depending on your personal preferences and the desired effects. Some popular methods include:

  • Eating fresh mushrooms on their own or mixed into a meal.
  • Drying and then powdering the mushrooms for use in teas, pill capsules, or as an addition to other foods. This also allows for long-term storage.
  • Brewing B+ mushroom tea by boiling dried or fresh mushrooms in water for 15-20 minutes, then straining the liquid and drinking it.
  • Incorporating B+ mushrooms into smoothies or other drinks to mask the taste.

Regardless of how you choose to consume B+ mushrooms, it is essential to start with a low dose and proceed with caution, as the effects can be potent and long-lasting. For some shelf-life directions regarding p. cubensis mushrooms, check out this article.

Dosing Recommendations 

When it comes to dosing B+ mushrooms, it is important to start with a low dose and gradually increase as needed. The strength of the mushrooms can vary widely depending on the strain, growing conditions, and other factors, so it is always best to err on the side of caution. For beginners, a small dose of .5 to 1.5 grams of dried mushrooms is recommended, while more experienced users may choose to take three to five grams or more for a stronger experience. It is also important to consider factors such as body weight, tolerance, and individual sensitivity when determining the appropriate dosage. Additionally, it is recommended to have a trusted friend or sitter present during the experience to provide support and assistance if needed.

Also note that B+ mushrooms have a different potency per each individual mushroom. To get a consistent dose, you can powder all the mushrooms together, mix thoroughly, and divide them up into portions by weight. Each portion will have an average potency of all of the mushrooms combined. 

Potency & Psychedelic Effects

The effects of B+ mushrooms can vary widely depending on the dosage and individual sensitivity. Some potential effects include:

  • Visual and auditory hallucinations
  • Changes in perception of time and space
  • Heightened emotional states
  • Increased creativity and introspection
  • Enhanced spiritual experiences
  • Altered thought patterns and beliefs
  • Intense feelings of euphoria or anxiety
  • Physical effects such as pupil dilation, increased heart rate, and changes in body temperature.

It is important to note that while some people may find these effects enjoyable and therapeutic, others may experience negative effects such as paranoia, confusion, or panic. It is essential to approach the use of B+ mushrooms with caution and to ensure a safe and supportive environment for the experience.

Growing B+ Mushrooms

Cultivation Of The B+ Strain 

Is B+ Easy To Grow?

While no mushroom is necessarily "easy" to grow, the B+ strain of P. Cubensis is one of the more welcoming for cultivators. Quick mycelial colonization, high resistance to temperature & contamination, and manageable fruiting conditions make this strain a hardy, reliable choice for mycologists. 

What Are the B+ Fruiting Conditions? 

The fruiting conditions for B+ mushrooms are similar to those of other strains of P. Cubensis. In order to produce fruiting bodies, the mycelium must be prepared in a bulk substrate such as a mix of vermiculite, coco coir, gypsum and water. The substrate should be pasteurized to prevent contamination by other fungi or bacteria. Once the mycelium has colonized the substrate, you can initiate fruiting conditions which include  high humidity and good air exchange. A temperature range of 75-85°F (24-29°C) is ideal for fruiting, and light is also necessary for the mushrooms to develop properly. Indirect sunlight works, or you can get fancy with an artificial lighting setup. Fruiting can take several days to several weeks, depending on the growing conditions and the strain of the mushrooms. With proper care and attention to these fruiting conditions, it is possible to produce a bountiful harvest of B+ mushrooms.

Bulk Substrate

Recommended Substrates for STB (Spawned to Bulk) 

For B+ mushrooms, we'd recommend using CVG which is Coco Coir, Vermiculite, and Gypsum. The purpose of CVG substrate is to maintain water capacity, providing an optimal growth medium for your spawn. If you are more advanced, feel free to get creative with your substrates. 

Recommended Growing Method for B+ Mushrooms

There are a lot of ways to grow mushrooms. For B+ mushrooms, we'd recommend creating agar cultures, inoculating sterilized grain, and then moving spawn to a bulk substrate (STB) to initiate fruiting. 

Growing Process (11 Steps) 

Note: This section is only permitted & intended for those in areas where growing P. Cubensis mushrooms is legal. Please contact your local government prior to reading this information. All information is for educational purposes ONLY, and should not be performed at home.  

    1. Set your intention: Do you want to grow for consumption (illegal in the USA), microscopy, for spore collection, or something else? Defining your intention will help you optimize your set-up. 

    2. Obtain B+ Mushroom Spores or Cultures: You can obtain mushroom spores or a spawn from a variety of sources, including online retailers and specialty gardening stores. Make sure that the spores or spawn are fresh and of high quality with no contaminationAt Eden shrooms, contamination should be the least of your issues. B+ spawn is illegal for purchase in the USA & many other places, so you'll likely need to go with spores. 

    3. Choose an inoculation medium: Many begin their process by inoculating agar plates with their syringe to create mycelium, and then move that mycelium to sterilized grain to create spawn. This article has more information on inoculating agar. If you don't want to go the agar route, you can inject spores or liquid culture directly onto sterile grain, or into an all-in-one grow bag. For B+ mushrooms, however, we'd recommend starting with agar, and moving the mycelium to sterile rye grain in a jar. The agar method makes it easier to detect early contamination, and it allows you to select the healthiest mycelium to transfer. Before you perform that task, however, there is still work to be done. 

    4. Sterilize the Grain: To prevent contamination, it is important to sterilize the grain you picked before adding the mushroom spores or culture. This can be done by putting rye grain into a jar and then using a pressure cooker. Once sterilized, you can prepare your grain jars to be introduced with spores or mycelium culture, depending on if you began with agar or not. 

    5. Introduce the Mycelium or Spores: If you began with agar, you will have some mycelium on the plate that you can move to your jar. Just flame-sterilize a scalpel, remove some tissue from the plate, and place it onto the grain. If you didn't use agar, simply inject the full syringe at different angles into the sterile grain. Make sure to be extremely clean during this process. Now, your mycelium or spores have met their nutrient-rich fuel source, and will begin to expand. 
    6. Provide the right environment for colonization: At this point, you need to let your mycelium colonize the grain, which requires specific conditions. B+ require a humid, dark environment with consistent temperature and low air circulation to grow. Many have recommended 75-85 degrees Fahrenheit as a relatively safe range for your mycelium to colonize the grain. Keep extremely clean, and be patient. 

    7. Shake & Break: Once your mycelium has colonized about 20% of the grain, you should shake up the jar to increase exposure points between mycelium & grain. Then, wait for the rest to be colonized. 
    8. Move grain spawn to pasteurized bulk substrate (STB): After the mycelium has fully colonized the rye grain, it will have formed a brick-like "cake" of mycelium. At this point, it's time to transfer your spawn to a bulk substrate. Common practice is to crumble up & mix your grain spawn with a CVG bulk substrate in your mono-tub. Using bulk substrate in a monotub can be confusing, so this guide should help you considerably. Make sure to pasteurize any monotub contents before adding spawn. Pasteurization will kill most of the microbes in your substrate, but not all, which is desirable so that remaining bacteria can ward off unwanted contaminants. 
    9. Initiate fruiting conditions: At this point, your grain spawn has been moved to a monotub and you need to initiate fruiting conditions in order for mushrooms to pin. To do this, you should always make sure to keep your substrate moist, introduce fresh air exchange (but not too much), and keep your mushrooms in indirect sunlight or artificial light. If you nail fruiting conditions and keep sterile, your mushrooms should start pinning and maturing! 
    10. Harvest the mushrooms: B+ mushrooms are best to harvest just after they break their veil. If you want to collect spore prints, you'll need to harvest once the caps completely flatten out. When the mushrooms are ready to harvest, carefully twist and pull them off at the base. Do not cut them off, as the exposed stumps become vectors for contamination. 

    11. Get A 2nd, 3rd, maybe 4th flush: After you harvest your first mushrooms, you still have some work left to do! At this point, you'd either have that same "cake" straight from the jar, or a "cake" that formed with the bulk substrate in the monotub. Regardless, you can let your "cake" continue to exist in its current conditions while maintaining humidity and fresh air exchange. That may be enough to see another flush. Or, if your cake appears to be too dry, you can dunk the cake in sterile water and put it back into the tub to try again.
