Questions
Good to know.
Something not covered here? Ask us and we will add it.
What is the difference between grain and substrate?
Grain is what you inoculate first. Once the mycelium has colonised it, that grain becomes spawn, and you mix it through the substrate: the bulk material your mushrooms fruit from.
Which grain should I choose?
Wheat is the all-rounder. Oats and milo break apart easily, and milo gives you the most inoculation points per kilo. Corn has the biggest kernels. The grain guide compares all four.
How much grain do I need for my substrate?
It depends on your spawn ratio. At 1:2 you use one part grain to two parts substrate, so 5kg of substrate takes 2.5kg of grain. The grow builder does the maths and picks the bag sizes.
What is an all-in-one grow bag?
Sterilised grain and substrate layered in one bag with an injection port. You inoculate the grain, let it colonise, then mix it through the substrate without opening the bag. They are coming soon.
How should I store my bags?
Keep them sealed, somewhere cool, clean and out of direct sunlight, and use them soon after they arrive.

The culture library
Living mycelium of the species worth growing at home, isolated and expanded on agar before it is bottled. First up: Blue oyster, Pink oyster, Lions mane, Reishi and Shiitake. Each culture is selected for vigorous, reliable growth on the grain and substrates we sell, so the whole range works together. Because they are grown here, there is no biosecurity paperwork and no week in a hot parcel van.
Formats when it opens: 10ml LC syringe and Colonised agar plate. Leave your email above to hear the day it lands.
Liquid culture or plate?
A liquid culture syringe is the easy one: shake, flame the needle, inject 2 to 5 ml through the port of a sterilised grain bag or an all-in-one. A colonised agar plate is for growers who keep a library: transfer wedges to fresh plates, or drop a wedge straight into grain in a still air box.
Start with the forgiving ones
Blue and pink oysters colonise fast and fruit on coir-based substrate. Lion's mane is gentle on hardwood and worth the wait. Shiitake and reishi are slower hardwood projects for a second or third grow. The species guides have the conditions for each.
Questions
About this product
What is a liquid culture syringe?
Live mycelium in a sterile nutrient solution. Inject it through the port of a sterilised grain bag and the mycelium colonises the grain into spawn.
How much do I use per bag?
2 to 5 ml per 1kg bag, spread across a couple of injection points if possible.
How long does a culture keep?
Months in the fridge for a healthy liquid culture; plates keep for weeks to months sealed and refrigerated. Use them while they are vigorous.
Are these gourmet species?
Yes. Gourmet (oysters, lion's mane, shiitake) and medicinal (reishi and friends). Everything here is for growing edible and medicinal mushrooms.
