Psychedelics Cup Denver ’24 Champion

I used Mountain Made Product’s HB4 substrate to grow the Albino Penis Envy that won Highest Total Active Alkaloids at the Psychedelic Cup in Denver, November ’24. I really like this substrate because it does not require casing which makes for a clean harvest with limited trimming. It’s also a very stable humidity control because of its coir to worm casting ratios. Both inputs are antimicrobial lowering the risk of contamination. I think the molasses helps excite the active alkaloids in a way that I haven’t seen before. HB4 is my go to substrate for all my grows now. If you want to know what the best cultivators are using for their substrate, the answer is HB4.

The bag itself is super tough. No leaks or rips, even after breaking up the grains twice. Everything stayed clean and my harvests looked fantastic.

Multi Grain Mix helped me get consistent, repeat flushes without the guesswork. Even as someone still learning, I felt set up for success. My first harvest was better than expected, and it’s motivating to see results like this with so little stress. Highly recommend for anyone wanting reliable outcomes.

I’ve tried mixing my own grains, but nothing compares to MGM. The moisture was perfect straight out of the bag, and my mushrooms grew strong and healthy. I really appreciated the quick support from the Mountain Made team when I had questions. I’m sticking with this for all my future grows.

I’ve been growing mushrooms for years, and this is one of the few grain mixes I’ll recommend. The colonization was fast and uniform, and the quality of the grains really stands out.

Our Latest Products

New to Mushroom Growing?

Can beginners successfully grow mushrooms at home?

Absolutely!

Our ready-to-use substrates and all-in-one grow bags are designed for simplicity. Just add spores or liquid culture, maintain the right conditions, and watch your mushrooms flourish.

What types of mushrooms are easiest for beginners to grow?

We recommend starting with dung-loving species.

Our HB4 substrate is perfect for these varieties, while our all-in-one grow bags offer flexibility for various species.

Both options provide an ideal growing medium to maximize your chances of success.

Do I need special equipment to start growing mushrooms?

To begin, you'll need just a few basic items:

  • Sterile gloves
  • 70% isopropyl alcohol spray
  • Spore syringe or liquid culture
  • Paper towels
  • Scissors or utility knife (for later use)
  • Spray bottle with distilled water
  • A warm, dark space for colonization
  • A place with indirect light for fruiting

How long does it typically take to grow mushrooms?

The growth cycle varies by species, but with our optimized substrates, you can expect to see results within 3-6 weeks for most varieties to colonize the Multigrain Spawn.
And 3-6 weeks once the Multigrains and HB4 Substrate are combined.

Remember, patience is key in mushroom cultivation – the wait is part of the magic!

What are the basic conditions needed for growing mushrooms?

Mushrooms thrive in specific conditions:

• Light: Indirect or ambient light (avoid direct sunlight)

• Humidity: 70-90%

• Temperature: 60-75°F (15-24°C) during fruiting and 72-78°F during colonization; for most dung loving varieties.

• Air exchange:
Consolidation: No fresh air.
Fruiting: Gentle, fresh air circulation

Practical tips:

• Use a closet or spare room for consistent conditions

• Mist with water 2-3 times daily during fruiting cycle to maintain moisture

How do you ship your products and how long does delivery typically take?

Are your products safe and legal to use?

Absolutely.

Our substrates are made from natural, high-quality ingredients and are legal for mushroom cultivation.

However, it's important to note that the legality of growing certain mushroom species varies by location. Always ensure you're complying with local laws and regulations.

About Us

Mountain Made has been a passion project from inception. Our founder and CEO started experimenting with growing his own mushrooms after they were credited with saving his life following a major traumatic brain injury (TBI) from a snowmobile accident. Despite the challenges of learning to walk and talk again, he defied conventional recovery expectations, thanks in part to his consumption of a blend of mushrooms before the accident. These mushrooms helped maintain his neuroplasticity, allowing the reconnection of damaged synapses.

Determined to find reliable substrates and grains to support his new journey, he dove into research and countless comparison grows. This dedication led to the development of the HB4 Substrate and Sterilized Multi Grains, designed for both beginners and seasoned growers. Our products provide the perfect biological foundation for healthy, fast, and repeated mycelium colonization with multiple successful flushes.

Our commitment to quality means you can trust our substrates to deliver consistent, reliable yields. We’ve crafted solutions that ensure robust mycelial growth and minimize contaminants. Today, Mountain Made is here to support your mushroom-growing journey, helping you achieve outstanding results with ease.

Our Facility

Mountain Made Products are produced at our facility in the Elk Mountain Range of Colorado. We’ve partnered with a test lab to ensure our products are successful at all stages of the grow.

We use the finest ingredients we can get our hands on to insure we have the smallest possible threshold for contamination as a result of our inputs. Sterility is a huge factor in the success of any mycologist so we’re doing our part to limit possible exposures.

We’ve spent years dialing our formulas, tweaking everything from cook times and temps to cure times and shelf life tests to have optimal inputs for home growers to commercial operations.
