Our USDA-certified organic red reishi (Ganoderma lucidum) grain spawn features a strain that produces beautiful, waxy, reddish-brown fruiting bodies that are highly prized for their medicinal properties. Due to its bitter flavor and tough texture, it is not recommended for culinary use. However, it is ideal for drying and making powders, teas, and stocks. It can also be extracted and made into a tincture.

Reishi mushrooms will only produce one flush. If growing antlers, use large grow bags to allow enough space for tall antlers to form. For larger yields, allow the mushrooms to form conks instead of antlers. (This is done by allowing lots of fresh air exchange in the growing environment.)

Recommended use:

  • Reishi grain spawn can be used for indoor production using sawdust-based sterile substrate.
  • Do not use grain spawn for log inoculation.
  • This is not a mushroom grow kit. Reishi grain spawn must be combined with a substrate in order to fruit.

Upon receiving your spawn:

Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Temp, Humidity & CO2 guide
Temperature 65-80°F  |  18-26°C
Humidity (Phase 1: Primordia) 95-100%
Humidity (Phase 2: Fruitbody) 85-95%
CO2 Sensitivity (Phase 1: Primordia) High CO2, keep in bag

  • Primordia -  The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”
  • Fruitbody - A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.
  • CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.
Indoor cultivation

Reishi mushroom grain spawn can be mixed into sterilized hardwood sawdust to create reishi substrate blocks.

Note: Grain spawn must be mixed with bulk substrate before you can fruit it. If you are new to mushroom cultivation, we recommend purchasing a book on mushroom cultivation if you are interested in pursuing this style of mushroom production as a hobby or profession.

Storing

If you don't plan to use immediately, you can refrigerate your spawn for up to 4 months.

Cooking

Reishi is bitter with a tough texture. For this reason, we don’t recommend it for culinary use. However, it can be dried and made into teas or powders. It can also be extracted to make tinctures.

Ingredients

Our grain spawn is USDA certified organic and made using organic cultures from our own culture bank. It contains a blend of locally sourced, organic, and non-GMO grains and supplements from farms in New England and North America.

Cautions & considerations

If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.

Frequently Asked Questions

No, grain spawn is not an all-in-one kit and cannot be used to fruit mushrooms out of the bag. Grain spawn must be mixed with bulk substrate before you can fruit it.

Grain spawn can be used in a wide variety of ways including indoor growing, outdoor growing, or to make more grain spawn. (Grain spawn can be used to make plug or sawdust spawn, not just other grain spawn.)

  • Indoors, you can mix grain spawn with bulk substrate to grow in bags, in containers, or to create fruiting cakes.
  • Outdoors, you can mix grain spawn with straw or wood chips to make beds and containers. (Note: Grain spawn can not be used for logs.)
  • A grain-to-grain transfer allows you to extend the life of your grain and create more grain spawn.

Our grain spawn is a proprietary blend that features nutrient-rich organic millet and wheat berries.
