Laboratory Information

Are your products made in a sterile environment?

All our cultures are prepared under strict lab conditions in a sterile environment (under a negative pressure laminar flow hood). We follow well practiced procedures and uphold the highest standards.


Are your cultures tested for contamination?

All cultures and spores are tested under microscope on intake and throughout their lifespan. Mother cultures are maintained in petri dishes or slant at 39 degrees F. Mother cultures are rotated out every 3 months for fresh aggressive culture.

How diluted/ far from the petri are your liquid cultures?

All of our samples are G2 

We create each jar of liquid culture directly from a living sample on petri plate. The reason we do this is because it allows us to see visible viability of the biological sample. constant monitoring for any contamination, and thriving fungi being transferred into each jar of nutrient broth. 


Fungi Sub-Strain Isolation Petri Dishes

Why do we use scotch tape when we inoculate a substrate bag?

Microfilter tape is not spore proof or autoclavable rendering it unusable for usage during inoculation or processes needing sealing. Always remember to throw away any exposed tape from a tape dispenser before pulling any tape you're going to use.

Why do we roll the grain bags?

We roll them to make sure that there aren’t large air pockets that will dry out the grain and cause the mycelium to grow poorly, or not at all in the air pockets.

Why does it matter that the bag is rolled and taped loosely?

As the mycelium grows it needs space to move between the rye berries and expand, When it is forced against the bag it causes premature metabolites to form and bruising of the mycelium.

What is an isolated sub-strain, and how does that effect things?

Liquid cultures are live mycelium suspended in a nutrient-rich broth. High-quality liquid cultures are prepared from an isolated sub-strain. This is because when multiple individuals (even from the same strain) are present on the same substrate they become competitive. The problem with this is that competing mycelium will not overgrow one another, but rather, marginalize and section itself off. This can give you varying results and effect yield in your flushes later on. If you want consistency, you must isolate a small colony with the traits you desire to prevent competition. Once isolated, a colony can take over an entire substrate unchallenged, and utilize every aspect of it. An isolated sub-strain will give you higher yields and more predictable results. All liquid culture sold at liquidfungi.com come from high-yielding isolated sub-strains, which we ourselves have isolated. Isolation is typically done in a petri dish on agar.

Growing Pains

Can I just inject this in the ground?

It isn't quite that simple. If you're looking to try outdoor "lazy" growing there are other methods. If you put your syringe in the ground and push you're only giving it a chance in that spot. When done properly some people have found the "seeding" method to be successful over time.


Can I use the microwave to sterilize?

You very much can use it to pasteurize! This is the least effective way with the most unpredictable results to try to "sterilize." In order to sterilize a substrate, you need temperatures higher than 250°F (121°C) (varies by altitude) for a minimum of 2 hours. Increasing the heat does not increase the temperature of boiling water (212° F) any further. You’ll need to add pressure to raise the temperature to 250°F (121°C) or above to kill off bacteria and fungal spores. Most mushroom growers will need 15 PSI of pressure to increase the temperature of the steam to 250°F (121°C). An autoclave or pressure cooker are commonly used to achieve sterilization.

Can I grow mushrooms on the dead tree in my yard?

Logs should be inoculated within 4 weeks of harvesting. Waiting longer (using a dead tree) your mycelium will have to outcompete the other fungi that have already started colonizing the log. Never cut dead, dying, or diseased trees for mushroom growing. You can't use either pasteurization or sterilization for your substrate. 

What is the general temperature range for mushrooms/ mycelium to live?

40-95 with a lot of variables per different varieties

What happens if the grain gets over cooked?

If grain gets overcooked, it begins to caramelize. This starts to process the sugars and keeps the grain more wet then normal. Leaving less food for the mycelium and no room for it to travel around the grain and colonize.

What do long stems and tiny caps mean?

It’s ALWAYS a problem with fresh air exchange. Start your investigation here.

What if water comes out of the hydro port on my lid?

The lid needs to be rebuilt. There shouldn’t be any water coming out of a liquid lid. We recomend tilting your jars over after inoculation to ensure seal.

What is the difference between liquid culture and spores?

I will start off by saying, other mycologists will be upset at me for explaining it this way. But, this is the easiest way for others to understand. Spores are like seeds and liquid culture is like sprouts/cuttings. Spores are dormant, waiting for the right environment to "wake up". Liquid culture is a living colony of mycelium, which is already hatched, and beyond the spore phase. 

What yield can I expect from a liquid culture syringe or spawn block?

A syringe/culture is a colony that can be expanded nearly indefinitely. Unlike farming, 1 sample does not result in a certain amount of crop. Virgin culture can be spread to new substrate blocks and fruited once incubated. With the proper sterile procedure, you can keep the one sample we send for years just by moving it to a new food source once in a while and not fruiting it.


Can you see things moving/ living under our microscope?

In order to stain a sample, it kills it. If you simply put it in a water suspension any movement you see could be/ probably is waves from the water.

Do you sell gift cards?

Yes, we do. These are issued electronically by email and each contains a unique reference number. Our gift vouchers are ideal if you’re not sure what to get that special person in your life. Simply buy a gift card.
