Pure Mushroom Spawn Policy

Aloha Medicinals is the industry’s leading company in certified organic mushroom grain spawn production. Our products are processed under controlled laboratory conditions giving you the best spawn available today.

When an order is placed, we do our best to ship your products in time; however, spawn takes time to grow and it will be shipped only when it is optimally ready.

We encourage our customers to wait until their whole order is ready to ship rather than shipping piecemeal to ensure the best shipping rates.

Mushroom grain spawn purity is guaranteed by our Class 100 Clean Rooms and checked by our QC crew before shipping the product to you.

Mushroom grain spawn is a delicate product. The customer is responsible for selecting the shipping options. We recommend you to pick the fastest shipping option that ensures the arrival of a quality spawn to your destination. For this reason grain spawn cannot be shipped overseas. If you want to pick a cheaper shipping option that takes two days to arrive to destination, we are ready to change our packaging method in order to make sure that the product will arrive to its destination in good condition. However, OVERNIGHT SHIPPING IS STRONGLY RECOMMENDED!

Once a packed product is shipped we cannot guaranty safe arrival to its destination. If the product arrives late or is not in prime condition when it arrives, you will need to file a claim with the shipping company. We assume that customers placing an order for grain spawn are knowledgeable of mushroom growing techniques. If that is not the case we offer consulting on how to grow mushrooms efficiently.

Always clearly state what mushroom species and strain that you would like us to prepare for you as grain spawn. We encourage you to use Latin names and the strain ID’s posted on the website.


Shipping of Organic Mushroom Grain Spawn

*Mushroom Spawn is not eligible for free shipping.

Delivery time for spawn orders is strongly connected to the strain type that is ordered. Fast growing strains usually need up to 3 weeks until they are shipped to customers while some others need more time.

Because the mushroom spawn is sensitive when exposed to prolonged high or low temperatures (which is the case with USPS), we strongly recommend faster delivery using FedEx Services. When ordering large quantities, another option is to use freight service with a refrigerated truck.

In order to find out the shipping cost for a certain quantity of spawn please provide us the following information:
