What is the Penis Envy Grow Bag?

This grow bag contains a nutrient-rich substrate that is fully colonised with healthy Psilocybe cubensis mycelium. This means that the most delicate stages of the cultivation process have already been completed, allowing you to start the next growth phase straight away.

Penis Envy is one of the better-known cubensis varieties and is often chosen by growers looking for a more compact, sturdier and more distinctive growth form.

Why choose Penis Envy?

Penis Envy is particularly prized for its unique growth characteristics. The strain generally develops more slowly than many standard cubensis strains, but often produces sturdy and compact fruiting bodies.

• Fully colonised substrate
• Ready for the fruiting phase straight away
• No spore syringe or sterilisation required
• Compact and sturdy fruiting bodies
• Suitable for experienced growers
• On average, two to four flushes possible

This grow bag is particularly suitable for growers who already have some experience and are looking for a strain that requires more attention and stability.

Who is this grow bag suitable for?

Penis Envy is less beginner-friendly than strains such as Golden Teacher or B+. The strain is more sensitive to fluctuations in temperature, humidity and ventilation. That’s why this grow bag is best suited to growers who can work carefully and hygienically.

• Experienced growers
• Users looking for a more challenging strain
• Growers with a stable indoor environment
• Lovers of compact, sturdy buds
• Growers who prioritise quality over speed

Growth characteristics of Penis Envy

Penis Envy is characterised by a slower and more compact growth pattern. Whilst some strains develop more quickly, this variety requires more patience and precision.

• Slower development than many other cubensis species
• Thick and firm fruiting bodies
• Compact growth habit
• Less frequent, but often heavier harvests
• Distinctive shape that differs from standard cubensis varieties

Due to these characteristics, the focus with Penis Envy is more on stability, care and quality than on speed.

How do you use the Penis Envy Grow Bag?

As the substrate is fully colonised, you can start the fruiting phase straight away. Ensure a clean working environment and keep conditions as stable as possible.

Important: Small slit below the air filter

Below the air filter on the grow bag, there is a small slit made by the manufacturer. This opening allows excess CO₂ and pressure to escape if the grow bag becomes inflated during the growing process. This is normal and is not damage. You do not need to do anything, and the opening should not be sealed or taped.

1. Place the grow bag in a bright spot out of direct sunlight.
2. Maintain a stable temperature of between approximately 20°C and 24°C.
3. Ensure there is sufficient fresh air.
4. Check the humidity regularly.
5. Always work in a clean environment and touch the inside of the bag as little as possible.

As Penis Envy is more sensitive to changes in its environment, a stable temperature and good air circulation are particularly important.

What can you expect during cultivation?

Penis Envy generally grows more slowly than many other Psilocybe cubensis varieties. The fruiting bodies are often thicker, more compact and firmer in structure.

Under suitable conditions, two to four flushes are usually possible. The final yield depends on care, hygiene, temperature, humidity and correct hydration between harvests.

Because each stage of cultivation has different points of attention, it helps to understand what happens during development. Read more about the cultivation process.

Key factors for successful cultivation are:

• A constant temperature
• Sufficient humidity
• Regular air exchange
• Working carefully and hygienically
• Proper hydration between flushes

How does Penis Envy compare to other strains?
