Sterile Substrate FAQ

Sterile substrates should be kept at room temperature and out of direct sunlight.

If kept at room temperature and out of direct sunlight, sterile substrates can be stored for several months before use.

Sterile substrates do not require refrigeration, we recommend storing at room temperature. If kept at room temperature and out of direct sunlight, all sterile substrates can be stored for several months before use.

Sterile substrates are processed in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.

Yes! In fact, we made the following monotub tek instruction video which includes Boomr Bag.

When used as an ingredient in your substrate, coco coir does need to be pasteurized or sterilized. When used as a casing layer on fully colonized substrate, it does not need to be pasteurized or sterilized. This is because the risk of contamination is significantly lower in fully colonized substrate.

Each spawn bag contains our proprietary blend featuring hydrated, nutrient-rich organic millet and wheat berries.

We recommend you let your Injection Port Bag sit for 1-2 weeks before injection. This will expose any issues that may have occurred in shipping and prevent wasted spores or culture syringes. If you do find that your product is compromised, please email us at info@northspore.com.

We recommend using 2.5-5ccs per 3lb injection port bag. We do not typically recommend using an entire syringe in one bag. Doing so adds excessive moisture which can create over saturation in the bag. This over-saturation can pool and is prone to being anaerobic. Due to this, the mycelium will have a hard time colonizing. If you ordered your bag online, we recommend waiting two weeks after receipt before using it. This waiting period will expose any issues that may have occurred in transit and prevent wasted spores.

The Boomr Bag features a proprietary blend of composted horse manure, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!)

With Boomr Bag, you can grow the dung-loving mushroom of your choice. It's an ideal substrate for any mushroom species that prefers a nutrient-rich media, including Agaricus sp., shaggy mane, oyster mushrooms, and more!

We recommended 1 lb of colonized grain spawn for each 5 lb Boomr Bag or Wood Lovr. Higher inoculation rates may improve your success. Be sure to mix your grain spawn thoroughly into your substrate. We always recommend clean hands and latex gloves to reduce the introduction of contaminants.

You can use your Boomr Bag in a monotub, filter bag, or outdoor bed.

A "boomer" is any mushroom that grows rapidly. And because we formulated Boomr Bag to maximize your mushroom yield, the name seemed fitting :-)

Wood Lovr contains a combination of micro-to-macro particle sizes of premium North American hardwood chips and sawdust. Additional nitrogen supplementation helps to speed up growth and maximize yield.

With your WoodLovr bag, you can grow the wood-loving mushroom of your choice. It's an ideal substrate for any mushroom species that prefers a hardwood based media. This includes oyster mushrooms, lion’s mane, nameko, and more!

We recommended 1 lb of colonized grain spawn for each 5 lb Boomr Bag or Wood Lovr. Higher inoculation rates may improve your success. Be sure to mix your grain spawn thoroughly into your substrate. We always recommend clean hands and latex gloves to reduce the introduction of contaminants.

You can use your Wood Lovr blend in a monotub, filter bag, or outdoor bed.
