Pre-Pasteurized Mushroom Compost

This is an excellent bulk substrate. GIANT thick fruits. I mean huge. The flavor was so intense. I used only 1 of their sterilized rye bags and 4 pounds of this sub. It was fully colonized in less than a week. Didn't yield a whole lot bc of the ratio (instructions only call for 2.5 lbs. of compost but I used 4), but 9 mini shoe box tubs gave me produced over 20 Oz dry!
