Our shiitake mushroom block is fully inoculated and ready-to-grow when they arrive at your door. If you’ve already ordered a growing kit from us in the past, all you’ll need to grow more mushrooms is one of these blocks. Like all the shiitake mushroom blocks we sell, these are made of just 4 all-natural and organic materials: wheat bran, maple sawdust, water, and strain CS-321 mycelium spawn (spores that have colonized). Certified organic by the Oregon Department Of Agriculture.
By providing this option, we hope to reduce unnecessary waste and save you money at the same time. Additionally, free shipping is included with your order. If however, you require the full mushroom grow kit, please click the link here or below.
