What is the use of mushroom spawn?
It is the base for growing mushrooms. You can use this spawn to move mycelium to any substance (substrate) if you want to grow mushrooms. You can utilize different substrates like logs, cardboard, straw, wood chips, and others.
What is the difference between mushroom spores and spawn?
Seeds (and spores for that matter!) are a genetic grab-bag dependent on two individual sets of genetic material, while spawn is a single genetic culture that can be propagated indefinitely from the same 'master'.
How long does mushroom spawn last?
Use the mushroom spawn within 2-4 months for the best results. Even in your fridge's ideal conditions, mushroom spawn won't last forever. Spawn usually live for 2-4 months in cold storage. Be sure to use the spawn within that time so your mushrooms grow properly.
How long does mushroom spawn take to grow?
14 to 21 daysA complete spawn run usually requires 14 to 21 days. Once the compost is fully grown with spawn, the next step in production is at hand.
What is mushroom spawn made of?
In the spawn-production process, mycelium from a mushroom culture is placed onto steam-sterilized grain, and in time the mycelium completely grows through the grain. This grain/mycelium mixture is called spawn, and spawn is used to "seed" mushroom compost.
How many spawns does a mushroom have?
Mushroom spores are produced in the gills. Spores are microscopic spheres roughly comparable to the seeds of higher plants. These spores are produced in large numbers in the gills. An 8-cm mushroom produces as many as 40 million spores an hour.
How much mushroom spawn do I need?
Go for a 10-20% ratio, ie. If you are making a 25 lb log, use 2.5-5 lbs of spawn. This is probably higher than required, but helps increase your chances of success.
Can you use rice as grain spawn?
Many different types of grains can be used for spawn – including wheat, rye, brown rice, white rice, wild bird seed and even popcorn.
How do you store spawn in your house?
For longer storage, refrigerate the spawn for up to 3 months. If you use a partial bag of spawn, store the remaining spawn in its original bag, folding the top down from the filter patch and clipping to secure. Pink Oyster grain spawn CANNOT be refrigerated and should be used within two weeks of receiving.
How long does it take for a jar to fully colonize?
Depending on the species of mushrooms, it can take about 1-3 weeks before the jar is fully colonized. At this time you can either add it to a bulk substrate or do a grain to grain transfer to make even more spawn!
Can you reuse spawn bags?
Reuse the Bag Although you probably want to start with new bags when making fruiting blocks or propagating spawn bags, you can always reuse your bags for other purposes, as long has you haven't cut the bag open for fruiting.
Why is it important to choose a mushroom spawn supplier?
Choosing the right supplier is important because you want to ensure their methods were sterile, leading to a higher rate of success for your mushrooms. I personally use BetterFungi.
What is plug spawn?
Plug spawn uses wooden dowels—either made of solid wood or of compressed sawdust —as the substrate. They are most often used to inoculate solid wooden logs. Simply drill a hole in the log and insert a plug. Plug spawn can also be used to inoculate other substrate types, especially those made of wood fiber, like cardboard. Plug spawn does not do as well for grain or straw.
What grains are good for grain spawn?
Not all grains are equal for use in grain spawn [iii]. Rye is considered the gold standard because it has a good nutritional balance, holds a lot of water, and the grains hold their shape. The problem for the hobbyist is that whole rye grain is not available in grocery stores, or anywhere else, in small, convenient quantities. Wheat is almost as good, and is available in convenient small batches in health-food stores. Millet has the advantage of very small size; mycelium can colonize it very quickly. It’s good to mix with other grains. Sorghum is useful for commercial-scale growers because it is inexpensive. Barley, brown rice, and popcorn (whole, not popped!) all work well enough for use by hobbyists and are readily available in small batches. The seed mixes sold to feed birds (often called wild bird seed, or WBS) also make good, convenient grain spawn for use at a hobbyist, provided the mix does not contain sunflower seed hulls.
How do spores grow?
A grower might put spores from different strains of the same species onto a sterile agar plate. The agar mixture is there as a food source. The spores will germinate and mate, producing a new genetic individual—a new strain. The advantage of starting with an agar plate, not some other substrate, is that the growth of the young mycelium is easy to see, and if any other fungi or any bacteria start growing (weeds in the garden, essentially), or if any other problem develops, it’s obvious. Starting over at this stage does not cost a lot of money or waste much substrate.
Why is it important to choose a reputable mushroom supplier?
Choosing the right supplier is important because you want to ensure their methods were sterile, leading to a higher rate of success for your mushrooms.
Is liquid spawn a substrate?
Liquid spawn is not really spawn—it is not a substrate colonized by mycelium. Instead, is it water mixed with either spores or a mycelium slurry. It, too, can be used to inoculate substrates, though.
Can you make grain spawn with millet?
Grain spawn can be made with virtually any type of grain or a mix of grains. Rye and millet are both popular. Grain spawn is a good option for inoculating all types of indoor grow set-ups, and grain provides better nutrition for the growing fungus than sawdust does. The only major problem is that birds and rodents like grain, too, and will happily dig up and eat any grain spawn used outside.
What is spawn in mushrooms?
Spawn is the carrier that holds a specific strain of mushroom mycelium in stasis until you, the cultivator, are ready to transfer it into another substrate such as a wood log, straw, compost etc. Spawn can be myceliated grain, sawdust, and wooden dowels (plugs and pegs). The goal of the spawn is to spread out bits of mycelium into its final habitat where it can grow, colonize, digest food and ultimately fruit.
How do you make spawn?
To make spawn, we incubate specialty mushroom strains in our laboratory, then grow them into a variety of forms for your use, including sawdust, grain, plugs (hardwood dowels), thimbles and pegs. Each of these, once colonized by mycelium, is referred to as "spawn."
What is a thimble spawn?
Thimble spawn, like plug spawn, is made in a measured amount. Thimble spawn is suited for use in natural log inoculation. It has a self sealing foam cap knit to the top of a spawn "thimble," so unlike other sawdust-based spawns, no waxing is necessary although in very dry climates, growers may opt to wax over the foam seal as well. Thimbles are bigger than plugs, so colonization time is equivalent to sawdust spawn inoculations. Thimble spawn is especially prone to drying in low rain climates. Having access to irrigation water, or arranging logs in low stack or raft configurations on the forest floor is helpful to achieving a successful spawn run in drought conditions.
What is plug spawn?
Plug spawn is wooden doweling, 5/16" (8.5mm) x 1" pieces, colonized with mycelium of a specific fungus. Using simply a hammer, these hardwood dowels can be easily tapped into the drilled holes of a log. Plugs are great for small projects because they're easy to use, require no special tools, and are available in small quantities. Once the log is inoculated, the inoculation site is sealed with wax to prevent the plug from drying out.
Why is spawn preferred in log growers?
Preferred spawn of many commercial log growers because spawn delivery can be mechanized with specialized tools.
Is grain spawn an attractant?
Undisturbed by critters when grown outdoors (except for occasional woodpeckers) unlike grain spawn, which can be an attractant.
What is mushroom spawn?
Mushroom spawn is simply any substance that has been inoculated with mycelium, the vegetative growth of a fungus. Mycelium, a thread-like collection of cells, is to a mushroom like an apple tree is to an apple. You need to have one as the base for producing the other.
How long does mushroom spawn last?
Mushroom spawn is a "use it or lose it" product, and rarely lasts beyond 2 months. Thus you should use it as soon as possible after it arrives. If not, refrigerate it to prolong its life span. Keep in mind that you're still working against the clock, so bust out that spawn as soon as you can!
What type of mushroom spawn is best for your project?
A general rule of thumb is to match your spawn to your substrate. For example, if you want to grow mushrooms on logs, a wood-based spawn such as plugs or sawdust is best.
What is sawdust spawn?
Sawdust. Sawdust Spawn is sterilized sawdust that has been inoculated with mycelium, often by grain spawn. The sawdust is usually made out of some type of hardwood with pieces neither too large nor too fine (a few mm in diameter). Sawdust spawn can be used to inoculate logs, outdoor mushroom beds, pasteurized straw, cardboard, ...
Why do mushrooms spawn in sawdust?
One of the main advantages of mushroom spawn in the form of sawdust is the size of the particles. Because they are so small and numerous, there are many more inoculation points for the mycelium to grow into the substrate. This results in faster mycelium colonization with less time for contaminants to take hold.
What is the substrate used for mushrooms?
You need to have one as the base for producing the other. The spawn is used to transfer mycelium onto any material from which mushrooms will grow, called a substrate. There are many different kinds of substrates, with straw, cardboard, logs, and wood chips just being a few examples.
What is grain spawn?
Grain. Grain spawn is sterilized grain that has been inoculated with spores or a sterile culture of mycelium. Many types of grain can be used with rye and millet being some of the most common. Other choices are corn, wheat, and different cereal grains. I've even had good luck with popcorn!
What is mushroom spawn?
Mushroom spawn is simply a carrier substrate that has been inoculated with and colonized by a particular strain of mushroom mycelium. What is mycelium, you may be wondering. Well, technically, the word “mushroom” refers to the fruiting body of a fungus, and mycelium is the rest of the fungus.
Sawdust Spawn
As the name implies, sawdust spawn is sawdust that’s been inoculated with mycelia. Sawdust spawn is usually sold in special plastic bags that have a filter patch so the mycelia can “breathe” but contaminants cannot enter and spoil the spawn. Large-scale commercial growers use this kind of spawn because it’s the least expensive.
Sources for Spawn and Other Supplies
Hopefully, we’ve helped you sort out which kind of spawn is best for your project. If you’re ready to get started, we recommend Field and Forest Products for both kinds of spawn, along with all the other tools you might need. Additionally, they have a handy tree-species video that tells you which species is ideal for growing which kind of mushroom.

How to sterilize mushroom spawn?
Some of the tools such as knives and tweezers can be sterilized by placing the tips or blades into the flame of a Bunsen burner or a similar clean heat source. Jars and growth media can be boiled for at least an hour to sterilize them and the work environment can be cleaned with a 70 percent solution of ethanol to remove contaminants. When everything is clean and sterile, the mother culture prepared from spores and the mycelium in the millet grains will exhibit very strong, healthy growth for high-quality mushroom spawn.
How to grow mushrooms in compost?
The success of mushroom farming and its yield depends on the purity and quality of the spawn used. Spawning is the method of mixing the spawn with compost. Spawn is added to compost at the rate of 0.5% by weight and mixed. Depending upon the growing system employed spawning is done by several methods.
