Spawn is a smaller amount of material on which the mycelium starts its growth before colonizing a substrate. There are various types of content to use in order to grow mushrooms:


Straws of rye, oat, and wheat will make a good base for the growth of fungus. These are cheap and easy to get from a feed store. You can use straw to grow different types of mushrooms.

Various mushrooms can easily grow in indoor environments on this versatile substrate. You should prepare this straw carefully because you have to protect your base from microbes. You can treat this base with the help of heat pasteurization.


You can grow mushrooms on logs because the log is easy to cut, easy to immunize with dowel progenies, and easy to incubate. While using logs, you should consider the nature of the wood and the cut of the log. You can select a similar type of wood to grow mushrooms on which mushrooms grow in the wilderness.

You should do some research on the mushrooms that you want to grow, as it will help you to save time and reduce heartache. Any hardwood with quick decomposing abilities may work well. Alder, beech, cottonwood, and ash are all good choices. You can also use oak, a thick hardwood that requires longer to produce your favorite mushrooms.

Late winter or early spring is the best season to cut logs. In this season, you will get healthy wood without any sign of decay or rot. There is no standard length for a log, but they should be a few feet long for easy handling and storage.

Particular types of mushrooms can grow better on logs than in straw beds, and a log will produce mushrooms for years as compared to straw.

Best Mushroom Substrate

Sometimes, it is confusing to find out which mushroom substrate is the best, and its answer is based on your personal requirements. As a general rule, you have to match spawn with the substrate; for instance, if you are interested in growing your mushrooms on logs, you can select wooden-based spawn, including sawdust and plugs.

Mycelium is familiar with this spawn material and the use of similar spawn, and it reduces colonization time. You should consider the type of mushroom that you are interested in growing.

Some mushrooms like lion’s mane, maitake, and reishi require a wood-based substrate, while oyster mushrooms can grow on anything. A simple guide to the growth of mushrooms is as under:

Grain: You can use indoor bags of sterilized straw and supplement with sawdust.

Sawdust: You will need wood-based substrates, such as wood chips, logs, and cardboard with sawdust supplement. It is suitable for outdoor beds of straw.

Dowel/Plug: This includes wood chips and logs.

You should consider your time and budget before selecting a mushroom substrate. Sterilized straw or logs take maximum time, and there will be lots of mess around these logs. You should purchase extra materials to manage this substrate.
