The Penis Envy XL Mushroom Grow Bag contains a fully colonized substrate with Psilocybe cubensis mycelium and is ready for the fruiting phase. This well-known variety is recognized for its slower development, sturdy fruiting bodies, and compact growth habit. Thanks to the fully colonized substrate, there is no need for inoculation, sterilization, or working with a spore syringe.
Penis Envy is a characteristic Psilocybe cubensis variety known for its compact growth, thick fruiting bodies, and relatively slow development.
Penis Envy distinguishes itself from many classic cubensis varieties through its sturdy build and atypical growth form. The species generally requires more patience and stable conditions, making it particularly interesting for growers who already have some experience.
What is the Penis Envy Grow Bag?
This grow bag contains a nutrient-rich substrate that is fully colonized with healthy Psilocybe cubensis Penis Envy mycelium. Consequently, the most sensitive steps of the cultivation process have already been completed, allowing you to start the next growth phase immediately.
Penis Envy is among the better-known cubensis varieties and is often chosen by growers seeking a more compact, sturdier, and more characteristic growth form.
Why choose Penis Envy?
Penis Envy is primarily valued for its unique growth character. The species generally develops slower than many standard cubensis varieties but often forms thick, sturdy, and compact fruiting bodies.
- Fully colonized substrate
- Ready for the fruiting phase
- No spore syringe or sterilization required
- Compact and sturdy fruiting bodies
- Characteristic Penis Envy growth form
- Suitable for growers with some experience
- Average of two to four flushes possible
This grow bag is particularly interesting for growers who already have some experience and are looking for a variety where stability, care, and patience are more important than rapid development.
Who is this grow bag suitable for?
Penis Envy is generally less beginner-friendly than species such as Golden Teacher or B+. The variety can react more sensitively to changes in temperature, humidity, and air exchange. Therefore, this grow bag is best suited for growers who can work carefully and hygienically.
- Experienced growers
- Growers seeking a more challenging cubensis variety
- Users with a stable indoor environment
- Enthusiasts of compact and sturdy fruiting bodies
- Growers who prioritize patience over rapid development
Growth characteristics of Penis Envy
Penis Envy distinguishes itself by its relatively slow and compact development. The fruiting bodies are generally thicker and sturdier than those of many classic Psilocybe cubensis varieties.
- Slower development than many standard cubensis species
- Thick and sturdy stems
- Compact fruiting bodies
- Characteristic growth form
- Greater emphasis on size and sturdiness than on high numbers
Due to these properties, the emphasis for Penis Envy lies primarily on stable conditions, patience, and careful maintenance during the fruiting phase.
How do you use the Penis Envy Grow Bag?
Since the substrate is fully colonized, you can start the fruiting phase immediately. Ensure a clean working environment and keep conditions as stable as possible.
Note: small cut under the air filter
Under the air filter of the grow bag, there is a small cut made by the manufacturer. This opening is intended to release excess COâ‚‚ and pressure when the grow bag bulges during the cultivation process. This is normal and not a defect. You do not need to do anything about this, and the opening does not need to be taped off.

- Place the grow bag in a bright spot without direct sunlight.
- Maintain a stable temperature between approximately 20°C and 24°C.
- Ensure sufficient fresh air.
- Check the humidity regularly.
- Work cleanly and touch the inside of the bag as little as possible.
Stable conditions are extra important for Penis Envy due to its relatively slow development. Avoid large fluctuations and allow the mycelium sufficient time to form fruiting bodies.
What can you expect during cultivation?
Penis Envy generally develops slower than many other Psilocybe cubensis varieties. The fruiting bodies are often thick, compact, and sturdy in structure. The exact shape and size may vary per flush.
Under suitable conditions, two to four flushes are usually possible. The final yield depends on care, hygiene, temperature, humidity, and correct hydration between harvest rounds.
Important factors for a successful grow are:
- A constant temperature
- Sufficient humidity
- Regular air exchange
- Careful and hygienic work
- Correct hydration between flushes
- Sufficient patience during development
How does Penis Envy compare to other species?
Within the Psilocybe cubensis range, Penis Envy is known as a more demanding variety with a compact and sturdy growth form. The species generally develops slower than various classic cubensis varieties.
- Slower development than Golden Teacher
- Compacter and thicker fruiting bodies than B+
- More demanding than many beginner-friendly cubensis species
- Different growth form than albino variants such as True Albino Teacher
The precise development varies per cultivation. Temperature, humidity, air exchange, and the condition of the mycelium influence the final result.
