## Overview

This 100-gram pack of Golden Oyster Mushroom Spawn by BetterFungi offers a high germination rate mycelium designed for growing gourmet and medicinal mushrooms on straw or sawdust substrates.

## Description

Growing your own mushrooms on straw logs or sawdust blocks is the perfect way to enjoy fresh mushrooms at home. It is a fun project to engage in and is low maintenance. Even if you do not have a large backyard, mushroom growing can be a great addition to your urban garden . Any hardwood loving mushrooms can be grown on straw, wood chips or sawdust blocks, including Shiitake, Oysters, Reishi, and Lion’s Mane. Mushroom cultivation involves first "inoculating" the substrate of your choice with mushroom mycelium, and then allowing the mycelium to colonize over a period of 2-3 weeks. When the substrate is fully colonized- and the conditions, such as light, moisture, and temperature, are right- the mushrooms will emerge from the substreate and can be harvested and enjoyed.

Review: The golden oyster mushroom spawn arrived on time, and the mycelium was white and healthy - I'm happy to have found a strain of golden oyster mushrooms for their choice edibility and their ability to grow on used coffee grounds, hardwood sawdust, or cereal grains. We soak our substrate overnight to kill off any bacterial/fungal competition then incorporate the spawn into micro filtered grow bags using latex gloves. We also use a large plastic storage container with lid to act as a humid forest like environment. And we find between 60°-70° is optimal, preferably near a window to get natural cycles of light. Our kids enjoy the scientific aspect of watching mycelium convert different substrates into edible fruiting bodies and my partner and I love sauteed mushrooms, jalapenos, onions and butter with scrambled eggs. Thanks Mushroom Rush!
Review: Didn't take.. - I prepared a large bed of straw and the like, buried under several inches of soil and cultivated for several months and the mycelium never took. After the season, I dug the spot up and not a bit of mycelium was to be seen.

## Questions & Answers

**Q: Does the spawn arrive refrigerated/need to stay refrigerated before use?**
A: I did not refrigerate mine but I used it soon (days) after it arrived.

**Q: I'm going to grew in pasteurized straw in a 5 gal bucket. how much straw should i use if i layer this spawn? can i layer to top of bucket?**
A: Always fill to the top never leave sir gap

**Q: Can I just spread these out in the woods near my home for future growth?**
A: I would not recommend that.  Drilling holes in fallen logs and inserting inoculated plugs would be better.

**Q: how much substrate should I use for each 4 gram order? Also can I mix multiple of the same type of spawn to grow?**
A: I used 1 cup for 5lb bag. But it was not enough. 
Better if you not mix spawn.
