We love to talk to folks about mushrooms! However, please understand our phones are in place to service customer orders and general product inquiries. We are not a mushroom cultivation support hot line. Please accept our apologies if we are unable to answer all your questions in detail or address technical issues at length. Our staff will be happy to recommend the valuable and informative resources available to us, these books and videos will address all your questions and inquiries in much deeper detail. We only offer mushroom cultivation consultation services at a negotiated contract rate. Thanks for understanding!

East Tennessee offers an incredibly diverse mushroom ecosystem. We are blessed to have a fairly abundant wild mushroom season spanning April through early November. Our good friend and collaborator Dr. Whitey Hitchcock has been foraging wild mushrooms in the area for decades and has recently expanded his services to include private guided mushroom tours for small groups. If you are interested in setting something up during mushroom season, please contact us and we can assist with the arrangements. Please understand foraging services are limited to East Tennessee, and more specifically the area surrounding Knoxville. Dr. Whitey will also be teaching mushroom identification and foraging classes throughout the season our workshop and consultation page for more information.
YES! We are expanding our events calendar to include more workshop, demostrations, and classes. We host workshops at our facility in South Knoxville and we often travel to other locations to perform demos, workshops, or participate in discussion groups. Please check our workshop and consultation page for more information. If you are interested in having us come out to your event, please contact us by phone or email with more information.

Everything Mushroom grow kits are guaranteed to produce a satisfying experience for all skill levels. If you have experienced a kit that has not functioned as anticipated, or failed to produce, please contact us and we will make additional arrangements!

Our staff will be happy to review the procedures followed and offer suggestions or guidance for success, we may determine your kit needs to be replaced, or simply offer suggestions on how to "revive" a dormant kit. Please contact us at the numbers below during our business hours and we'll be happy to assist.

Pre-sterilized un-colonized products such as rye spawn bags, PF Tek jars, and pre-poured plates are NOT guaranteed due to dependency of customer care and knowledge with these products to produce desired results. These products MUST be used within 2 days after receipt of your order for best results.

Mushroom culture syringe products are tested for viability, and are NOT guaranteed, as success depends upon customer process and treatment of cultures upon receipt. Pre-colonized products such as ready-to-grow kits, blocks, grain and plug spawn should be refrigerated until ready to use, and are all guaranteed sterile for 30 days after receipt of purchase. THIS DOES NOT INCLUDE ANY SALE ITEMS OR BARGAIN PRODUCTS. Due to dependency of customer care and knowledge with these products to produce desired results, we do not guarantee replacements or refunds of these products beyond mold issues. Should you find any of these products unclean or contaminated, contact us WITHIN 30 days of receipt, and we will make arrangements for replacement. There is NO guarantee if not contacted within 30 days of purchase. Please note that some ready-to-grow kits may eventually mold during their normal fruiting lifetime, this is natural, especially if the kit has already produced several flushes of mushrooms. For this reason, customers should USE PRODUCTS WITHIN 1 WEEK OF PURCHASE. Note to International customers: due to increased exposure and potential of longer transit times, we can not extend our standard replacement guarantee to customers receiving pre-sterilized product outside the USA.

Check out this shiitake log blog post. It pretty much sums it up, with some excellent directions and pictures of the mushroom log process.

You're looking for freshly harvested, disease free hardwoods. You'll want to cut the pieces about the length and diameter of your leg. You can also use the same practices to plug stumps and larger rounds, incubation and productions times may increase accordingly. Wood should be plugged within six weeks of harvest. Avoid wood that has had prolonged contact with the ground. Shiitake mushrooms perform best on white oak, although red oak is a close substitute. Other similar hardwoods will work, but not as well. Lion's mane mushrooms prefer beech. Oyster mushrooms work well on poplar, Although we have not had much luck with oysters on oaks, other growers report success with the denser woods. Avoid evergreen hardwoods, "furniture wood" such as cherry and walnut, soft woods, and conifers.
