All nutrients your mushrooms need, ready-packed in a 5-pound bag. We use organic materials mixed in with coco coir for aeration, gypsum, and water, for a simple yet effective mix bound to keep your mushrooms growing plenty! 

Minimal contamination risk

Each mushroom manure substrate bag is fully sterilized and sealed inside a durable bag. Each bag is also equipped with a self-healing injection port that improves safe inoculation rates.

Grow a wide variety of mushrooms

Manure mushroom substrate is most well-known for growing mushroom varieties like Psilocybe Cubensis and Psilocybe Semilanceata, but its nutrient-rich composition works great for lots of common dung-loving mushroom species like the button mushroom or portabello. Always check your local regulations to learn about what you can and can’t grow. 

 

With our bulk horse manure mushroom substrates, you’ll get bountiful harvests without having to worry about nasty contaminations or abnormal growths.

Manure-Based Mushroom Substrate FAQs

What is the perfect substrate for my mushroom culture?

Most mushrooms require their own specific combination of nutrients. This means that different mushroom varieties like oyster mushrooms and Lion's mane mushrooms might require different types of substrates. You'll need to research the appropriate type of substrate whenever you grow a new type.

Some of the most popular choices for substrate material are manure, CVG Mushroom Substrate 5#, straw, hardwood sawdust, coffee grounds, logs, and cardboard.

How do I know if my mushroom substrate is bad?

One of the biggest dangers of indoor mushroom growing is the risk of contaminating your substrate and your culture. Here are a few signs to look out for:

  • Strong, bad smell
  • Abnormal growths (misshapen or stunted mushrooms)
  • White or blue-green mold growing on the surface

All our substrates are carefully sterilised so that the risk of contamination is kept as close to 0 as possible. Shop today for a risk-free mushroom-growing journey. 

Do you ship in discreet packaging?

Yes, all our products will be shipped in plain brown boxes, so you can safely and discreetly begin your mushroom cultivation journey. Orders ship from "The Spawn Store".

How long does it take to grow mushrooms using aged manure substrate?

The growth time for dung-loving mushrooms usually ranges between 2-4 weeks from set-up. This time can vary depending on the specific conditions of your growing environment.

Yes, we do! For orders over $50, you can choose to pay in 4 instalments using ShopPay.
