Pre-Pasteurized Mushroom Compost

This stuff really is worth every penny, I mixed 1000 lbs of substrate and cooked 5 bales of straw this week. Id say this product outshines and outlast and outpreformes my attempts for 2 years consistently. THIS SUBSTRATE HAS NEVER CONTAMINATED ON ME! We got 4-5 flushes over 2 months with this compost. I threw away half of homemade attempts, never thrown away this bulk sub! js
