Mycosource Inc. is a small company that specializes in Spawn production for the cultivation of Shiitake and Oyster mushrooms on hardwood logs. We do not supply the raw hardwood logs. You cut or source logs so they are ready for inoculation in the spring. We deliver spawn on a ‘just-in-time’ basis during the outdoor hardwood log season in Canada – April to June. We take orders from January until March 31. NOTE We make spawn to fill confirmed orders and cannot promise supply if order is placed after the end of March.
AS OF APRIL 11/2017 WE ARE SOLD OUT OF TOOLS AND SUPPLIES AND WE HAVE ONLY ABOUT 10 BAGS OF SHIITAKE SPAWN AVAILABLE
These are “wood mushrooms” which means that they grow on wood (trees, fallen limbs, logs). They have high nutritional value.
Our premier product is sawdust spawn that is used to inoculate hardwood logs for outdoor hardwood log cultivation. PLEASE NOTE THAT WE ARE NOW SUPPLYING LOOSE SPAWN IN BAGS AND INOCUATION EQUIPMENT INCLUDING SEVERAL TYPES OF MANUAL AND SEMI-MANUAL INOCULATORS AS WELL AS WAX.
We ship spawn throughout Canada. We provide Customer Support to help you achieve success with your outdoor log cultivation project.
In addition we can produce bulk grain, and sawdust spawn on a contract basis for several other species of mushrooms, such as Reishi. We can also do contract sterilization of grain and/or your substrate mix.
We can also provide Consultation about indoor-based cultivation set up for a fee. This is done on a case-by-case basis.
We endeavor to act as an educational enterprise for the dissemination of products and information about mushrooms and mushroom cultivation as part of a diversified and sustainable forest ecosystem and are available for presentations on mushroom cultivation.
