2 x 5 lb. Sterilized Supplemented Oak Hardwood Substrate
The optimal fruiting medium is our enhanced hardwood substrate mushroom grow blocks. For cultivating mycelium, we utilize 100% organic oak sawdust that has been completely moistened. For best results, our hardwood substrate blocks are enriched with grain flour, sulfur, and calcium. To preserve the sterility of the block, we employ the thickest sacks possible. Each block weighs 5 pounds and comes in an extra-large bag, allowing for easy mixing after inoculation.
