Nothing on the market compares to our laboratory grade Psilocybe cubensis spawn. Premium genetics prepared in specialized lab conditions by our professional mycologists. Highest quality guaranteed.

Mega You Grow® Magic Mushroom Spawn

Our Mega You Grow® Magic Mushroom Spawn is the highest quality laboratory-grade mushroom mycelium culture available. It is a master grain spawn culture that is professionally prepared in our specialized mycology laboratory. MYG Magic Mushroom Spawn is fully colonized under the purest environmental conditions and guaranteed to arrive free of contamination.

Mega You Grow® Magic Mushroom Grain Spawn is made with the genetics of our proprietary strain, Golden Mammoth Psilocybe cubensis. It is a rapid colonizer, full of vigorous mycelium that provides dense growth and solid rhizomorphic spread. Our spawn is made with 100% certified organic, Canadian sourced grain. Simply the best!

Mushroom Spawn vs. Spores

The main Spawn vs. Spores differences are laid out adjacent boxes. For home and industry mycologists, the most important differences between spawn and spores are contamination risk, standardizes genetic purity, germination time and reliability of production.

Spawn ~ Mushroom spawn is live fungal culture made from carefully selected, isolated genetic material cloned from a single strain of the desired mushroom species. Genetic tissue cultures are expertly selected from the strongest, biggest, fastest growing mushrooms with the most desirable qualities (potency, purity, resistance to disease, appearance). The isolated genetic material is grown into vigorous live mycelium cultures on sterile agar plates in order to clone the best genetics. To make spawn, the pure genetic cultures are inoculated onto specific nutrient rich organic grains, which have been steamed and sterilized, to produce robust, vibrant live mushroom mycelium of the desired fungi species.

Spores ~ In contrast, mushroom spores are the most basic dormant genetic material of the mushroom species. Each spore contains a myriad of strains of the mushroom species. This mixture of multiple strains allows different variations to be injected into the environment with the hopes that some will be able to thrive under various environmental conditions. Most of the spores released will not ever bear fruit. Mushroom spore syringes also contain a mixture of bacteria and viruses, due to the inability to isolate pure genetic material from other environmental influences. 

Why is MYG Magic Mushroom Spawn Important?

Our spawn is strong, reliable, and vibrant and made with 100% certified organic materials. Using our MYG Magic Mushroom Spawn allows you to grow rapidly by increasing the colonization success of your substrate for densely populated flushes which maximize yields. Rather than growing from untested spores, which may or may not provide clean successful reproduction, our MYG Magic Mushroom Spawn provides you with professionally selected, isolated clone cultures of the mushroom strains that have proven to be the biggest, strongest, fastest growing and most resistance to disease/defects/contamination as well as those with ideal purity and potency. Using our Mega You Grow® Magic Mushroom Spawn allows you to work with the highest quality lab-grade mycelium selected for the most productive fungi strains to maximize your success and mitigate risk!

Our high grade MYG® Magic Mushroom Spawn is Pure and Organic

Mega You Grow® Magic Mushroom Spawn is made by growing our potent proprietary Golden Mammoth Psilocybe cubensis mycelium through 100% certified organic grain that has been steamed to unlock its full nutrient profile and sterilized to destroy any competing microorganisms.

Mega You Grow® Magic Mushroom Spawn is Truly Robust

Mega You Grow® Magic Mushroom master culture is a is highly active mycelium grain spawn to seed your mycology projects with the best available genetics – selected specifically for rapid colonization of substrate beds, big fruiting bodies, maximum yields, multiple flushes, and resistance to disease, defects and contamination. Our Mega You Grow® Magic Mushroom Spawn will unlock the highest potential of your mushroom projects!

MYG Magic Mushroom Spawn is always made from our strongest most robust tissue cultures, isolated to enhance ideal characteristics, and directly seeded into the sterilized grain under strictly controlled sterile laboratory conditions. We never use liquid tissue cultures or spores – these produce uncertain, unreliable genetic profiles and questionable results. Our spawn is strong, reliable and vibrant, made with 100% certified organic ingredients. MYG Magic Mushroom Spawn allows you to grow rapidly by increasing the successful colonization of your substrate for densely populated flushes to maximize your yields.

How is Mega You Grow® Magic Mushroom Spawn Made?

Our Magic Mushroom Spawn is made under the strictest specialized laboratory conditions in our purpose built mycology facility by expert mycologist with over 70 years experience between them! Our spawn is made by inoculating (seeding) steamed and sterilized organic grains with carefully selected mushroom tissue agar cultures, then incubating the inoculated grain under perfect conditions to allow the genetically pure tissue culture to grow through the grain to become vibrant mycelium.

Our mushroom tissue cultures are selected from the strongest, biggest, fastest growing mushrooms with the most desirable qualities (potency, purity, resistance to disease, appearance) and then grown into vigorous cultures on sterile agar plates to clone the best genetic material. These tissue cultures are then grown onto carefully selected nutrient rich organic grains to produce robust, vibrant live fungal growth of the desired mushroom species.

Spawn is a single genetic culture that can be propagated indefinitely from the same ‘Master’ culture. Our spawn is always made from our strongest most robust tissue cultures, isolated to enhance ideal characteristics, directly seeded into the sterilized grain under strictly controlled sterile laboratory conditions. We never use liquid tissue cultures or spores – these produce uncertain, unreliable genetic profiles and questionable results.

What Does High Quality Magic Mushroom Spawn Look Like?

High quality mushroom spawn should appear as vigorous white mycelium growing densely on the dark pellets of grain. The white mushroom mycelium will bind the grain together in a dense brick that can be broken up to seed the substrate. High quality mushroom spawn will have rhizomorphic growth with millions of tiny threads reaching through the grain. Each of these rhizomorphic threads will branch out into a multitude of pins for fruiting. We use 100% Canadian sourced certified organic grain to provide the ideal nutrient profile needed to feed, grow and strengthen the specific strain of mushroom mycelium that we are producing to elicit a strong rhizomorphic growth profile.

Mega You Grow® Magic Mushroom Spawn is Highly Rhizomorphic meaning it will send out strong growth branches that reach through your substrate to provide multiple arms for mushroom fruiting. Strongly rhizomorphic spawn creates more pins earlier resulting in greater yields and multiple flushes.

What is Mushroom Spawn? 

Spawn is the vibrant living fungal culture, called mushroom mycelium, growing on a substrate. Mushroom spawn is the foundation of mushroom cultivation and the most important part of growing mushrooms. With high quality spawn, you decrease your chances of contamination and increase your output by maximizing your yields and your success. Without spawn, you can’t grow mushrooms! With spawn you have the live mushroom mycelium already grown and ready to take off into your fruiting bed to grow!

Spawn is like the seeds of a mushroom. However, mushroom spawn is made from fungal genetics that have been carefully selected and expertly cloned for consistent production of a particular cultivar of mushroom species. It is made in a specialized mycology lab by growing a vibrant tissue master culture of mycelium (the living fungal culture) onto sterilized grain and colonizing it under careful conditions until it is perfectly ripe and ready to seed your substrate bed. In other words, spawn is the magic germinated genetic material from which amazing mushrooms grow!
