The First-Flush Promise

Our Guarantee to You

Growing mushrooms is a partnership between you and nature. We provide fully colonized, healthy mycelium, and you provide the right fruiting conditions.

Follow the instructions and get no viable first harvest? We’ll replace the kit.

If you activate your kit within 21 days of delivery, follow the setup instructions, and still don't get a viable first flush, we will make it right.

Eligibility & Activation

Timeframe: Your kit must be activated (opened and exposed to fruiting conditions) within 21 days of delivery.
Proper Storage: If you are not activating the kit immediately upon arrival, it must be stored correctly prior to activation (e.g., kept refrigerated or in a cool, dark room, depending on the specific strain's instructions).
Following Instructions: The kit must be set up, slit, and misted according to the provided instructional card.

What Is (and Isn't) Covered

Covered

• Kits that completely fail to pin or fruit despite following all instructions.
• Mycelium blocks that arrive with visible contamination already present before opening.
• Kits that were significantly damaged in transit.

Not Covered

• Contamination introduced after setup (e.g., fully opening the top of the bag instead of cutting a slit, handling the block with dirty hands).
• Kits left sitting for over 21 days before activation.
• Extreme environmental neglect (left in direct sunlight, hot cars, freezing temps, or completely drying out).
• Second or third flushes (only the first harvest is guaranteed).

How to Submit a Claim

We want to help you succeed! Sometimes a stubborn kit just needs a little troubleshooting. To submit a claim, please follow these steps:

Take Photos: Snap a few clear photos of your grow kit. We need to see the slit/opening and the environment where the kit is sitting.
Email Us: Send an email to support@shroomage.com with the subject line "First-Flush Promise - [Your Order #]".
Include Details: Briefly describe your misting routine, the date you activated it, and attach your photos.

Our mycologists will review your photos. Often, we can give you a quick adjustment to get your kit pinning! If it's truly a dud, we'll arrange your replacement immediately.

Replacement Limits & Shipping

Shipping Responsibility: We will provide the replacement grow kit entirely free of charge. We only ask that you cover the standard shipping fee to get the new box to your door.
Limits: This promise is strictly limited to one replacement kit per original kit ordered.
Substitutions: In the rare event that your specific mushroom strain is out of stock, we will offer you a comparable strain of your choice as a replacement.
