If you'd like to place an order by phone or have questions, our business hours are Monday - Friday, 8 a.m. to 4:00 p.m. CT. If you have a time-sensitive order requiring expedited shipping services, we recommend calling us at 800-792-6220. We accept VISA, Master Card, American Express, Discover, as well as mailed in money orders and personal checks (US funds only). If using a check/money order, please call us first to place the order so that we can give you an order total and number to reference on your check. Your order will be sent when your payment is received. Catalog and online pricing are subject to change without notice. Although our goal is to deliver the highest quality spawn and supplies in a timely manner, spawn is a biological product and may need to be grown, so it may not be immediately available for shipment.

Hawaii Orders

Hawaii orders require an import permit from the Hawaii Department of Agriculture. Permits can be emailed to shipping@fieldforest.net (or mailed to Field and Forest Products). Please do not place an order before obtaining your permit!

Tax Exemption

We collect sales tax from the following states: AR, GA, IL, IN, KY, MD, ME, MI, MN, NC, NJ, OH, VA, VT, WI, AND WV. Schools and universities are tax exempt, but we must have the tax ID (state sales tax exemption form or tax ID number) on file prior to order placement to reflect that status. Commercial growers should also file their tax exemption form with us in order to qualify for tax exempt status. Forms for tax exemption are available online on each state's Department of Revenue website. We encourage tax exempt customers to provide their tax exempt paperwork to us at least 48 business hours prior to placing an online order. Not doing so will result in a non-exempt order which cannot be refunded. Phone orders can be placed prior to exemption filing, but cannot be processed until we have received the tax exemption form. All tax exempt forms should be emailed to jhk@fieldforest.net


Tools and other merchandise are returnable only upon the discretion and approval of Field and Forest Products, Inc. An approved return authorization from Field and Forest Products, Inc. is required for return of these items. In the event that a return is authorized for any tool purchased, a restocking fee will apply. If an order is delayed, lost, or returned to us as a result of an entry error by Field and Forest Products, Inc., we will reship the order at our expense.

If an order is delayed, lost, or returned due to an error by customer (i.e., incorrect address provided, omission of different "ship to" address, etc.), customer will be responsible for additional shipping costs to reship order. If order is not returned to Field and Forest Products, Inc., customer will be charged for replacement merchandise as well. If customer chooses to cancel the order instead, we will refund merchandise cost, once shipment has been returned to us by carrier. Shipping costs will not be refunded.


PLEASE INSPECT YOUR ORDER IMMEDIATELY UPON ARRIVAL! Spawn damaged in shipment will not be replaced unless customer notifies us within 24 hours of receipt. All sales of spawn, tools, and other merchandise are considered final and are returnable only upon the discretion of Field and Forest Products, Inc. An approved return authorization from Field and Forest Products, Inc. is required for return of these items.


If customer chooses to cancel an order prior to shipment, the order will be cancelled in full and refunded full order amount if payment has been processed, with the exception of volume order discount commitments and custom orders.

Volume Order Discount Commitments: If order is part of a multiple shipment agreement involving volume discounting and the commitment has not yet been met, customer will be responsible for paying the balance due resulting from readjusting the billing difference based on actual number of bags purchased.

Custom Orders: Custom orders may only be cancelled if production of spawn has not yet occurred.

Volume Discount Pricing

Volume discount pricing for spawn applies to orders placed at one time, not accruing over a period of time or season. A large order may be broken up to ship over a maximum period of 8 weeks. Standing orders that meet our highest volume discount quantity when placed are exempt from this time restriction.

Limited Warranty & Liability

We warrant that our spawn is vigorous, and capable of producing mushrooms under proper growing conditions. Mushroom cultivation is farming and depends upon factors outside our control, such as substrate quality, environmental conditions and maintenance, Field and Forest Products cannot and does not guarantee success in terms of mushroom production.

Field and Forest Products' spawn, cultures or other products are not to be sold, transferred, marketed, or assigned, without our prior written consent. Customers may only use, re-isolate, or further propagate our spawn/cultures for their own personal use and/or consumption. Please note that spawn used for this purpose or used in a way not recommended by Field and Forest Products will NOT be covered under warranty or replaced for any reason. Use of Field and Forest Products' name, product names, trademarks, photographs, product descriptions, written materials, and/or any other copyrights without prior written consent is also strictly prohibited.

Covid Shipping Update:

All three major shipping carriers (FedEx, UPS, and USPS) have temporarily suspended their service guarantees for both ground AND air shipments (with the exception of FedEx Overnight Air Service), because of the increase in shipping demand due to COVID. This means that the carriers will not allow a claim to be filed for a delayed shipment for any reason.

We are letting our customers know so that they are aware of the situation and can make the best choice possible in deciding on when to have their order ship (taking into consideration temperatures while in transit, possible delivery delays, etc.)
