Sealing Wax for Mushroom Plugs

5 Reviews

All-natural sealing wax for mushroom plugs.


    • All natural soy wax
    • Works better than paraffin wax
    • Comes with complete instructions
    • Safe and easy to use

Our all-natural soy sealing wax is used for sealing the holes after plugging your log with our mycelium plugs. Soy wax is durable yet flexible and much better than using plastic-based paraffin wax. We recommend approximately 5oz of sealing wax per bag of plugs.

Soy wax has a low melt temperature (185* F) so take great care in heating wax to avoid over-heating and possible fire hazards.

The instructions on our mushroom plug spawn outline detailed and safe use of sealing wax.

Retail orders are typically shipped within three business days of purchase (likely sooner). We ship products out Monday – Thursday. Anything purchased after 4pm PST Thursday will be shipped the following Monday. Please note that overnight and/or expedited shipping times refer to the time something takes to ship according to the shipping method, rather than the time it takes to send an order.

We send out orders as soon as possible. Please keep in mind that any mushroom kits or spawn will need to be protected from extreme cold and heat. Mycelium (the base of the mushrooms) is alive and should not be left out in the sun or snow. Please be ready to accept your order as it arrives.

What are the key ingredients to growing mushrooms successfully?

High humidity, indirect light, a good amount of fresh air, and temperatures ranging from 55-75 degrees F. For more information, check out our page on growing mushrooms.

When should I start my mushroom kit?

All mushroom kits should be started within a week of receiving them. If you can't start your kit right away it can be safely refrigerated for up to 4 weeks.

Works well

The wax was easily melted and one bag was enough to seal more than 100 plugs. I just put the wax into a can, and the can in a pot with water and heated it on the stove until the wax melted.

Cascadia sealing wax

Cascadia sealing wax was easily melted and brushed onto Shiitake plugs in alderwood logs. I didn't realize how well the sealing wax performed until I swapped stories with friends who used other types of waxes and had nothing but trouble. For instance, wax that was designed to seal wine bottles required long heating times at high temperatures and then proved to be brittle in freezing temperatures. In comparison, Cascadia's sealing wax remained flexible in cold temperatures and adhered to the plugged logs. Cascadia's sealing wax is well worth the price.
