Reishi (Ganoderma lucium) is not really a mushroom that is used for cooking. It is most often used to make tea.

It has been used as natural medicine in Asia for a long time and have recently become popular among biohackers.

Reishi is an slow growing mushroom. It may take up to 1-2 months before you can harvest your first mushrooms from the kit after it have been started.

Our grow kits are made at the site of our mushroom laboratory located in the Finnish countryside.
Just follow the instructions and you can enjoy fresh mushrooms grown at home in a couple of weeks time!

When making the grow kits we mix sawdust, wheat bran and water together.

When the substrate mix have been packaged into grow bags they go through sterilisation.

After the bags have been cooled down we inoculate them with mycelium that is grown on site.

That is it! No chemicals or nasty stuff!

Made to order

Mushroom mycelium is a fresh product and you will get the best results if the mycelium is as fresh as possible upon arrival.

Because of this we make all products containing mushroom mycelium to order.
If we were to keep stock of mycelium products it would in the end make for a worse product. 

The normal lead time of most products containing mycelium is 2-3 weeks.

The mycelium need some time to ”take over” or colonize the growth substrate once they have been manufactored.

Otherwise there is a risk that the mycelium would not be strong enough to survive the shipping process.

The lead time however varies and is not set in stone. 

Sometimes orders are shipped faster due to planned overproduction.

During busier periods the lead times might be longer due to production bottlenecks.

If you want your order to be delivered in a certain date range please let us know about it in the message field in the shopping cart.

We try our best to accommodate delivery date requests.
