Used extensively in almost all stages of mushroom production to give essential nutrients to mycelial growth. A safe nutritional supplement for beginners which has noticeable effects if compared to grows without. Good price when ordered in bulk. ~ Han

looks to be making a huge difference in my A/B tests growing oysters (as I was told it would following advice on other websites). Pretty cheap stuff considering the benefits it makes and free shipping. Top drawer.
