Liquid Cultures As No Spore Method

Can You Grow Psilocybe Mushrooms Without Spores?

Are you curious about cultivating psilocybin mushrooms (illegal in the USA) but want to explore alternative methods that don't involve spores? In this comprehensive guide, we will provide valuable insights and practical tips to help you successfully grow psilocybe mushrooms without spores. You have 3 options: using Liquid Cultures, Cloning Tissue, or Buying Grain Spawn. However, starting with spores is still the recommended method. 

For people in the US, cultivation is 100% illegal and should not be attempted, and this post is for educational value only. Our spores should only be used for microscopy & taxonomy, and never cultivation.

Pro's & Cons of Spores For Psilocybe Cultivation

Using spores over other methods like liquid culture and cloning has its benefits, but it also has some pretty steep downsides. Before we dive into spore-less methods of cultivation, take a look at the pros and cons: 


- Readily Available

- Affordable

- Extended shelf-life 

- Genetic Diversity 


- Slow germination period

- Inconsistent results

- Labor intensive 

- Subject to contamination

Overall, while spores provide a traditional and widely-used approach to psilocybin mushroom cultivation, they come with certain challenges and time constraints. Instead, let's look at some other options, starting with the all-popular "Liquid Cultures". 

Liquid Cultures

No Spores Method #1: Liquid Cultures 

What is a Liquid Culture? 

A liquid culture is a technique used in mushroom cultivation that involves growing mycelium in a nutrient-rich liquid medium. In a liquid culture, a small tissue sample is transferred to a sterilized liquid solution, often containing nutrients like sugars, vitamins, and minerals. The mycelium then grows and spreads throughout the liquid, forming a network of branching hyphae (aka 'Liquid Culture').

Benefits of Liquid Culture over Spores

Using a liquid culture for mushroom cultivation offers several notable benefits compared to using spores. Firstly, liquid cultures provide a faster and more reliable method of propagating mycelium. Unlike spores, which require germination, liquid cultures already contain actively growing mycelium, allowing for quicker colonization of substrates. This saves time and reduces the risk of contamination during the initial stages of cultivation as well.

The controlled environment of a liquid culture also facilitates the selection and propagation of desired genetic traits, resulting in consistent and predictable mushroom yields. Overall, liquid cultures offer greater efficiency, increased success rates, and a more streamlined process for cultivating mushrooms compared to relying solely on spores.

How to Make a Liquid Culture for P. Cubensis

Unfortunately, magic mushroom liquid cultures are illegal for sale in most of the USA due to the fact that the mycelium contains psilocybin. Thus, you'll have to start with a spore syringe and agar to create your own liquid culture, which by the way is also illegal in most of the USA. For those of you in legal jurisdictions, creating a liquid culture from a spore syringe can be achieved through the following simple four-step process:

  1. Inoculate The Agar: Drop 1 or 2 drops of spore solution onto your agar plate and gently streak it across the plate with an inoculation loop. Now you must wait to allow the a culture to grow on the agar. 

  2. Transfer mycelium to liquid medium: Using a sterile scalpel, draw a small amount of mycelium from the agar and place it gently it into the sterilized liquid medium. It's critical to work in a clean and sterile environment to prevent contamination.

  3. Incubate the liquid culture: Seal the container containing the liquid culture and place it in a warm and dark environment with a stable temperature. This encourages the growth of mycelium from the tissue. Monitor the culture regularly to ensure proper growth and check for any signs of contamination.

  4. Transfer and use the liquid culture: Once the liquid culture has shown substantial mycelial growth, it can be used to inoculate sterilized substrates or further expanded through transfers into fresh liquid medium. It is important to maintain sterile conditions throughout the transfer process to avoid contamination. At about 20 colonization, you can shake up the contents to disperse mycelium throughout. 

Note: It is crucial to research and follow specific techniques and safety measures for liquid culture preparation to ensure successful results and minimize risks of contamination. Remember to check with your local laws before performing any of these activities. This information should be taken as education only. 

Cloning Mushroom Tissue

No Spores Method #2: Cloning Tissue

What Is A Mushroom Clone?

A mushroom clone refers to a genetically identical replicate of a parent mushroom. It is created through a process called cloning, where a small piece of mycelium or tissue from a mature mushroom is isolated and transferred to a suitable growing medium. Unlike spores, which can result in genetic variation, mushroom clones maintain the exact genetic traits and characteristics of their parent.

Benefits of Cloning Over Using Spores 

Cloning a psilocybe mushroom allows growers to reproduce desirable traits consistently, such as high potency or unique physical features. Mushroom clones are commonly used in commercial cultivation to ensure a predictable and uniform crop. They offer growers a reliable method for propagating specific strains and preserving desirable attributes from generation to generation. For example, let's say that you have a giant, beautiful mushroom that you want more of. You can take tissue from that specific mushroom and cultivate new mushrooms that look just like the original. 

How to Clone a P. Cubensis Mushroom

Cloning Psilocybe mushrooms can be accomplished through the following simple three-step process:

  1. Obtain a tissue sample: Using a sterile scalpel or clean scissors, carefully cut a small piece of tissue from a mature mushroom. It is preferable to choose a healthy and fully developed mushroom for optimal results.

  2. Transfer the tissue to agar: Sterilize a petri dish containing agar, a nutrient-rich gelatinous medium, following proper sterilization techniques. Place the tissue sample onto the agar surface, ensuring it makes direct contact. Seal the petri dish and incubate it in a controlled environment suitable for mycelial growth. At this point, the dormant mycelium (the tissue) has been introduced to a new food source and is ready to continue colonization. 

  3. Cultivate mycelium: Monitor the petri dish regularly for signs of mycelial growth, which should appear as white, thread-like strands spreading from the tissue sample. Once the mycelium has developed sufficiently, it can be transferred to a sterile grain jar for further cultivation or expanded through additional transfers to agar or liquid culture.

Grain Spawn bag

No Spores Method #3: Buying Grain Spawn

What is Grain Spawn

Grain spawn is a more advanced and evolved product in mushroom cultivation compared to spores or liquid cultures. It involves sterilized grain, typically rye, that has been pre-inoculated with mycelium. With grain spawn, the mycelium is already established and ready to grow, eliminating the need for spores to germinate or mycelium to develop from a liquid culture. If you buy grain spawn, you're basically skipping all of the "hard" steps. Grain spawn also allows for easy distribution and storage, making it a preferred choice for commercial mushroom cultivation. Overall, grain spawn provides a convenient and effective means of expanding mushroom cultures, enabling cultivators to achieve higher yields with greater efficiency. Once again, Psilocybin-containing grain spawn is illegal for sale in the USA, which is why we reiterate that Spore Syringes are your best option. 

Why Use Grain Spawn Instead of Spores

Psilocybe grain spawn is often preferred over spores for mushroom cultivation due to several compelling reasons. Firstly, grain spawn offers a higher level of reliability and consistency. Unlike spores, which may contain genetic variations and uncertainties, grain spawn is a clone of a specific mushroom strain. This ensures that the cultivated mushrooms will exhibit the desired characteristics, such as potency and appearance, consistently.

Secondly, grain spawn provides a faster overall process. Since the mycelium is already established in the grains, it can readily colonize the substrate, reducing the time required for the mushrooms to mature. Additionally, grain spawn is easier to handle and distribute compared to spores. It can be stored for longer periods and transported conveniently, making it a practical choice for both small-scale and commercial cultivators.


Congratulations! You have reached the end of this comprehensive guide on how to grow psilocybe mushrooms without spores. By exploring alternative methods such as liquid cultures, tissue cultures, and grain spawn, you have learned how to cultivate these fascinating mushrooms using innovative techniques. Growing magic mushrooms without spores opens up new possibilities for cultivators, offering faster colonization, increased consistency, and the ability to propagate specific genetic strains. However, that is not to say that spores don't have their place. For the most serious of mycologists, spores will still serve your needs quite nicely.
