Powered by Mushroom Mycelium™ - NO FILLERS!
A ‘filler’ is an additive, or an ingredient that either serves to add bulk or weight to the end product, but that has no discernible health benefit. There are no ‘fillers’ used in Host Defense products. Rather, both the mushroom mycelium and the fermented rice substrate in our supplements have been researched, tested, and shown to offer health-supporting benefits.*
Latin Name: Grifola frondosa
Fruiting Temperature: 50–60 °F
Maitake is a delicious, soft-fleshed polypore that grows in northern, temperate deciduous forests. It grows well on hardwood sawdust/chips/bran, and typically produces one large mushroom per flush. This species requires more attention to detail than other mushrooms.
FP's ready-to-inoculate, pure mushroom Grain Master Jar is a first- or second-generation Grain Master in a reusable 1-gallon glass jar fitted with an autoclavable lid and Synthetic Filter Disc (approximate yield per jar: ⅔ gallon). Each Grain Master can be expanded up to 1000 times its mass.
Each order of mushroom grain spawn is custom-made: lead time for grain spawn is 6–8 weeks from date of order.
Please note: Unlike our ready-to-grow Mushroom Patches and Mushroom Plug Spawn, our Grain Spawn does not come with instructions. It is assumed that the purchaser is sufficiently familiar with mushroom culture technique to utilize these cultures. The books Growing Gourmet & Medicinal Mushrooms and The Mushroom Cultivator are essential tools in this endeavor.
By purchasing Mushroom Grain Spawn, the customer agrees to the terms of the Mushroom Spawn Sale Agreement.
Please note: depending on a number of factors, it may be necessary to ship your order via an expedited shipping process in order to ensure the viability. If this is necessary, your order will be placed on hold until a Customer Service Representative can contact you to present your shipping options and costs.
Shipping to Hawaii
The Hawaii State Department of Agriculture has recently increased their restrictions on the importation of live mushroom mycelium into the islands. This affects the sale of Fungi Perfecti's Plug Spawn for Log and Stump Cultivation and Pure Mushroom Spawn and Cultures. Customers in Hawaii wishing to purchase any of these products will need to first apply for and receive an Import Permit from the HSDA Plant Quarantine Branch. Additionally, importation of our MycoGrow™ products is completely prohibited.
The permit can be downloaded in Adobe Acrobat format online here.
