Making the world of mushrooms accessible to all
North Spore was launched in 2014 by a mycologist, an organic farmer, and a photojournalist -- three college friends brought together through their shared love of the mycological world.
What began as a simple love for mushroom foraging and cultivation quickly developed into an obsession with all things fungi. From there, an urban mushroom farm was born, as was the desire to spread the spore to the masses.

Excellent for grain spawn
I exclusively use these filters for my grain spawn. I have yet to have a contamination. I'll be ordering more of these since they've earned my trust!
