How To Get Mushroom Grass Seeds

Growing mushrooms can be a fascinating and rewarding hobby. One of the first steps in cultivating mushrooms at home is obtaining mushroom grass seeds, also known as mushroom spores. These seeds are essential for starting the growth process and can be obtained through various methods. In this article, I’ll share my personal experiences and insights on how to acquire mushroom grass seeds for your own mushroom-growing endeavors.

Understanding Mushroom Grass Seeds

Before delving into how to obtain mushroom grass seeds, it’s important to understand what they are. Mushroom grass seeds, or spores, are the reproductive cells of mushrooms. They are microscopic and can be found on the gills or pores of mature mushrooms. These spores are used to propagate new mushroom growth and are a crucial component in the cultivation process.

Harvesting Spores from Mature Mushrooms

One method to acquire mushroom grass seeds is by harvesting spores from mature mushrooms. To do this, select a mature mushroom with open gills or pores. Place the cap of the mushroom on a piece of paper or glass and allow it to sit for several hours. During this time, the spores will be released and form a visible pattern on the surface below the mushroom cap. Once a sufficient amount of spores has been collected, they can be carefully scraped into a sterile container for later use.

Purchasing Mushroom Spore Syringes

Another popular method for obtaining mushroom grass seeds is by purchasing spore syringes from reputable suppliers. These spore syringes are filled with concentrated mushroom spores and are commonly used for inoculating substrates to initiate mushroom growth. It’s crucial to source spore syringes from trusted vendors to ensure the quality and viability of the spores.

Utilizing Spore Prints

Spore prints are another viable option for acquiring mushroom grass seeds. To create a spore print, place a mature mushroom cap, gills facing down, on a piece of paper or glass. Cover the mushroom with a glass or bowl to create a humid environment, and let it sit for a day or two. The released spores will form a distinctive pattern on the surface below, which can then be carefully collected and stored for future use.

My Personal Preference

Personally, I prefer harvesting spores from mature mushrooms as it allows me to observe the entire life cycle of the mushrooms I’m cultivating. There’s a sense of satisfaction in being involved in every stage of the process, from spore collection to full mushroom growth.


Obtaining mushroom grass seeds is a crucial first step in the mushroom cultivation journey. Whether you choose to harvest spores from mature mushrooms, purchase spore syringes, or utilize spore prints, it’s essential to prioritize the quality and viability of the spores. With a bit of patience and attention to detail, you’ll be well on your way to growing your own bountiful mushrooms at home.
