BRF Jars - Organic Mushroom Substrate (6 Ct)

Introducing our Complete Mushroom Growing Kit in a Convenient Package Experience the convenience of our freshly crafted organic brown rice flour mushroom substrate jars! Key Features: You will receive a set of six 8-oz mason jars, each filled with our handcrafted organic brown rice flour and vermiculite mushroom substrate enriched with sulfur, calcium, and worm casting tea. The jar lids are equipped with a self-healing injection port and a .22-micron gas exchange filter for optimal growth conditions. Our jars are meticulously sterilized, cooled, and individually shrink-wrapped to seal in moisture and freshness, with the added benefit of containing any potential glass breakage during shipping. Safely store the sealed BRF jars in the refrigerator for up to 4 months, possibly longer. We've even achieved success with year-old test jars that were refrigerated. After harvesting the first flush of mushrooms, simply soak the mycelium cakes in bottled water and refrigerate for 12 hours
