CARING FOR SPAWN

Grain spawn is a living breathing organism that needs to be properly cared for in order to achieve the best results.

Here are some tips to get the most success with your spawn.

  • Be Quick!

    Try to use your grain spawn as soon as you get it. The fresher the better. It has likely traveled a long way and is ready to be used!

  • Store Properly

    If you do need to store it, do so in a cool, dry and dark environment. Most species will do well to refrigerate.

  • Use Proven Techniques

    If you are buying grain spawn, you should be reasonably knowledgeable in the techniques used to grow mushrooms from spawn.

  • Stay Clean

    Maintain a clean environment when working with grain spawn. Grain spawn is still susceptible to contamination, even when fully colonized. Proper sterile technique goes a long way!

USING YOUR SPAWN

You should be somewhat familiar with proper growing techniques before you buy your spawn. The most common methods of growing mushrooms using grain spawn are growing on staw, growing on supplemented sawdust or just growing in a garden bed. Check out our article on how to grow mushrooms from spawn , or check out one of these great books and learn from the best!

Growing on Straw

Add your spawn to properly pasteurized straw at a ratio of 5-15%. Mix the spawn in evenly to ensure multiple inoculation points. Pack poly tubing to make a straw log, cutting slits into the side. Hang in grow room for colonization and fruiting. See growing mushrooms on straw.

Growing on Sawdust

Some species grow better on supplemented sawdust, which needs to be fully sterilized. Inoculate fruiting blocks with grain spawn in front of a flow hood or similar sterile environment. See growing gourmet mushrooms on supplemented sawdust fruiting blocks.

FAQ

We will ship our spawn anywhere in the mainland US. If you live outside of the US, please contact us to see if we can make something work.
We guarantee that we will send you good quality spawn- the best we’ve got. If the spawn fails because of an error on our part, then yes- we will either replace or refund. We want you to be happy! That being said, if the spawn fails because it sat in a hot mailbox for three days, or improper techniques were used to grow it, then we will have to deal with that on a case by case basis.
