    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. Sharondale Mushroom Farm cannot and does not guarantee success in terms of mushroom production.

    All sales of spawn, tools, and other merchandise are considered final and are returnable or refundable only upon the discretion of Sharondale Mushroom Farm.

    Tools and other merchandise are returnable only upon the discretion and approval of Sharondale Mushroom Farm.

    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 Sharondale Mushroom Farm we will reship the order at our expense.

    PLEASE INSPECT YOUR ORDER IMMEDIATELY UPON ARRIVAL! Spawn damaged in shipment will not be replaced unless customer notifies us within 24 hours of receipt. We do not offer refunds for live items. Please do not ship live items back to Sharondale Mushroom Farm. If you suspect that your live item is damaged or defective, contact us immediately.
