FAQ

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.

Where's the injection port?

In an effort to reduce plastic use, we removed the injection port on our substrate bags.

Our substrate bags are not intended to be injected with spores or liquid culture. They're intended to be mixed with colonized grain in a grow bin.

How much colonized grain should I mix with this substrate?

We recommend mixing 3 lbs of colonized grain with 5-10 lbs of substrate.

What kind of mushrooms can I grow?

Dung-loving mushrooms!

How long can I keep the bag before using it?

Because our substrate is fully sterilized instead of pasteurized, 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 substrate avoids extreme temperatures, liquids, and direct sunlight. Do not open the bag until you're ready to use it!

Can I grow mushrooms directly in the substrate bag or do I need a grow bin?

We recommend mixing this substrate with colonized grain in a grow bin.

If you wish to grow directly inside your 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 instructions, video guides, and FAQs in our Help Center. If you still can't find the answer to your question, email us at grow@mushroomsupplies.com!
