Where can I find spores or liquid culture?
Although our products don't come with spores or liquid culture, you can easily find them online from several suppliers. We recommend sourcing them from Hellospore.com. Use checkout code MUSHROOMSUPPLIES for 5% off.
What kind of mushrooms can I grow?
Unlike our Grow Kit In-A-Bag™ and Substrate, you can use this grain bag for virtually any variety of mushrooms, including:
- dung-loving mushrooms
- wood-loving mushrooms such as lion's mane and oyster
How much substrate should I mix with this grain?
We recommend mixing 3 lbs of colonized with 5-10 lbs of substrate.
How long can I keep the bag before using it?
Because our grain is fully sterilized, it can last several months if stored correctly. We recommend keeping it in a box and placing it in a closet or cabinet. Make sure the grain avoids extreme temperatures, liquids, and direct sunlight.
Can I grow mushrooms directly in the grain bag or do I need a grow bin?
We recommend mixing this grain (once colonized) with substrate in a grow bin.
Although not recommended, if you wish to grow directly inside your grain or substrate bag, we suggest mixing 1 lb of colonized grain inside the substrate bag.
If your preferred method is to grow directly inside a bag, your best option is simply to get the all-in-one Grow Kit In-A-Bag™.
Where can I find step-by-step instructions?
You can find step-by-step videos, instructions ,and FAQs in the Guides section of the website. If you still can't find the answer to your question, email us at firstname.lastname@example.org!
Is my bag too wet or too dry?
We take special care to ensure each bag is perfectly hydrated and sterilized.
Please note that moisture and hardwood oak dust can settle toward the bottom of the bag during transit. Because of this, we recommend shaking your grain bag before inoculating it. This will help with mycelial growth by evenly distributing moisture.
