I am so excited to give this a second go around. I have had trouble finding spawn in Canada. I did find one good source for oysters and shitaki. But, I would really like some Portobello. Spores101.com was where I found my Canadian source. They have a small selection of edibles, reasonable prices and fast shipping. Does anyone know of a place in Canada to get some Portobello, or cermini, spawn?
