Lion's Mane Grain Master Bag
FP's ready-to-inoculate, pure mushroom Grain Spawn is offered in a disposable Spawn Bag with Filter Patch (approximate yield 1.25–1.5 gallon). Each unit is a first- or second-generation Grain Master that can be expanded up to 1000 times its mass.
Each order of mushroom grain spawn is custom-made: lead time for grain spawn is 2–4 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.
