How To Make Liquid Culture

Making liquid culture is a process that utilizes mushroom spores, mushroom fruit body, or another mycelium liquid culture to create a powerful and convenient solution used for growing mushrooms. If you find yourself wondering “why do these spores take so long to grow?”, spores to liquid culture is certain to fix those problems!

Our favorite LC recipe is a Light Malt Extract (LME) liquid culture recipe – but you can simply replace the LME in our recipe with 24mL honey if you wish.

Supplies Needed:

Light Malt Extract

Pressure cooker

Tin foil

Micropore tape


70% Alcohol

Distilled Water

Essentially the liquid culture recipe consists simply of 1g of LME (or 24mL of honey) per 600mL of water. You can inoculate this nutrient solution with either a multispore syringe or spore print, mushroom fruiting body, or another mushroom liquid culture.

Making Liquid Culture

1: Jar Prep

You can use for the most part any size jar. Simply make sure your jars and jar lids are cleaned very well, and then poke 1 hole in the lid of each jar with a screwdriver or syringes (tip – keep one extra lid unpoked for the next step). Be careful when doing this!

2: Filling the Jars

There is 2 options in this step – 1. You can calculate how much water and LME (or honey) you need and put that in a pot to heat on low for 5-10 minutes or 2. Simply fill each jar with water and the corresponding amount of LME and shake it up well (this is where the unpoked lid comes in).

3: Tin Foil/Micropore Placement

Again, you have 2 options here – you can fill the holes in the jar lids with tin foil (make sure it fits snug) or you can use micropore tape. Then after you do one or the other, cover each jar lid with tinfoil.

4: Sterilization of the Jars

Place the jars into your pressure cooker and sterilize them at 15psi for 35 to 40 minutes. Let them cool to at least room temperature before the next step.

5: How to Inoculate Liquid Culture

Ideally setup and sterilize your still air box or flow hood, otherwise sterilize the area of inoculation by wiping it down with alcohol.

Remove jars from pressure cooker, place them in the sterile area, remove tin foil from jars and wipe lids with alcohol wipes. If you put tin foil in the holes, take it out and place micropore tape over the hole.

For Multispore Syringe or Mushroom Culture Syringe: shake very well, (optional – flame sterilize needle), clean needle with alcohol wipe, lift up micropore tape, and inject 1-2cc of solution per 500mL.

For Fruit Body, Spore Print, or Agar Culture: Take piece of culture/fruit/pile of spores and simply dump them into the jar.

6: Mixing/Allow Colonization

Now you must mix this solution once a day. This can be done by shaking it up, or you can purchase a stir plate and metal stir bar that can use to mix it for you.

Liquid culture mycelium generally takes 24-72 hours to show noticeable growth (sometimes a bit longer for mushroom spore liquid culture) and can take 5-20 days to fully colonize. Using a liquid culture allows faster growth than spores, as it is contains already colonized mycelium – whereas multispore syringes and prints generally take 5-15 days to even begin forming noticeable mycelium. Check out our article on spore syringes vs. liquid cultures !

How to store liquid culture?

Liquid culture should be stored in the fridge, and can last up to 6 months. Do not let them freeze or get in high temperatures.

How long does liquid culture take to colonize grain?

Generally liquid culture should show noticeable mycelium growth on grain within 24-72 hours (although sometimes longer due to growth patterns) and takes about 5-15 days to colonize a jar of grains.

What is the best liquid culture recipe?

This is something that is for the most part subject to personal preference, supplies available, and other environmental factors. Generally our LME mushroom liquid culture recipe is one of the most simple and consistently effective, which is why we recommend it.

Safely buy Bitcoin or Ethereum with CashApp, Credit or Debit card

(Original Artwork by Emmaline Bailey)

This article will briefly explain how to purchase Bitcoin or Ethereum with credit debit in any country so that you can buy mushroom spores with cryptocurrency (Bitcoin, Ethereum, etc.). Please feel free to ask us any questions you might have! You can contact us on reddit at u/Psilocy3ibin or via email at

*Please note, if your order total is less than 0.001BTC you should use Coinbase or a similar exchange with a low withdraw fee (as CashApp does not allow withdraws below 0.001BTC)**

Although crypto currencies such as Bitcoin and Ethereum seem like risky business, you might be happily surprised to find out that they are actually safer and much less risky than most people think. To start off, they are decentralized (just like mushrooms/a mycelial network!) and from an investor standpoint, bitcoin actually has a lot more things in common with low risk assets like gold, US treasuries, and cash. Bitcoin and most other crypto currencies give the holder safe financial self custody of their assets, so it will still hold value even if all laws broke down tomorrow. Similar to gold, Bitcoin has a fixed supply and is borderless. So basically, crypto currencies like Bitcoin are a currency that gives the holder absolute power over their assets. To top it all off, crypto currencies run on extremely secure, complex, and digital blockchain technology that is considered to be much more efficient and accurate then a lot of modern-day technology that banks use. Oh yeah, did I mention websites like Coinbase, Coinmama, CEXIO and many other crypto currency exchanges are recognized by the most reputable banks in the world?

So lets get down to business, here is how to buy Bitcoin or Ethereum safely and easily anywhere in the world.

*If you have already made a purchase on our website and were directed here after you received the invoice containing the BTC or ETH address, then continue onto the steps below. If you would like to make a purchase on our site with Bitcoin or Ethereum, please make the purchase first and then follow this guide once you have received an email invoice from us containing the Bitcoin or Ethereum address to send the funds to. *

Step 1: Choose a crypto currency exchange to buy Bitcoin or Ethereum on. Here is a list of well known and safe exchanges that allow you to purchase crypto currency with your credit or debit card worldwide:

CashApp: & (note coinmama requires extra steps)

(there are many other trusted and safe exchanges, places like reddit provide tons of reviews and information on trusted and safe exchanges. Having trouble? Feel free to reach out to us with any questions you might have!)

Step 2: Follow the instructions on the exchange of your choice to purchase either Bitcoin or Ethereum with your desired payment method. Purchase the amount of BTC or ETH that was told to you in the invoice we sent.

Step 3: Once you have purchased the BTC or ETH required for your order, copy and paste the address we gave you in the invoice (keep in mind you can only send BTC to Bitcoin addresses and you can only send ETH to Ethereum addresses). **Double check and make sure THE ENTIRE ADDRESS was copy pasted, this is very important** Once you have verified that the address is copied correctly, follow the instructions below to send the BTC or ETH to our wallet on the site you have chosen: &,and%20the%20receiver’s%20wallet%20address.

And that’s it! Once you have sent the funds your order will be added to the paid order que and you will be notified once it has shipped. Please feel free to ask us any questions you might have!
