Dr.Mycs Growth Promotion Products

The growth promotion product line Colorado Cultures stands behind

Colorado Cultures sells primarily its own branded products — Sorghum AIO, Denver Dirt, Magical Gypsum, Fungi Fuel. But certain third-party products are too good to ignore. Dr.Myc Growth Promotion Products are one of those exceptions.

Colorado Cultures is a proud vendor of Dr.Myc products because the line consistently produces the kind of results that justify carrying another brand. Cultivators who try Dr.Myc once tend to incorporate it into their permanent cultivation stack — for growth promotion, substrate vitality, or both, depending on which variant they choose.

The Dr.Myc Growth Promotion Products line comes in three variants, each formulated for specific cultivation needs:

• MGP Plus — Growth promotion + Substrate Vitality
• MGP Pure — Maximum Gourmet/Medicinal Mushroom Growth Promotion
• Just the Trich — Substrate Vitality only (no MGP microbes for growth promotion)

Choose the variant that matches your cultivation priorities.

What "Growth Promotion" actually means

Growth promotion isn't fertilizer. Mushrooms don't take up nutrients the way plants do — they decompose substrate organic matter and absorb the broken-down compounds. Growth promotion supports the decomposition process so mycelium has more bioavailable material to grow with.

The Dr.Myc growth promotion approach typically involves:

• Beneficial microbial strains that pre-digest substrate components
• Enzymatic activity that accelerates substrate breakdown
• Antagonistic activity against contaminants (the good microbes out-compete the bad)
• Trace nutrient supplementation for mycelium cell wall and protein synthesis

The result: faster colonization, larger fruit bodies, more flushes per cycle, reduced contamination.

What "Substrate Vitality" means

Substrate vitality is broader than growth promotion. It refers to the overall health of the substrate microbiome — the community of microorganisms living alongside your mushroom mycelium.

A healthy substrate microbiome:

• Cycles nutrients efficiently between substrate and mycelium
• Resists contamination through diversity
• Maintains pH stability through buffer organisms
• Recovers quickly from disturbances (FAE cycles, humidity changes, etc.)
• Supports multi-flush cultivation by sustaining substrate quality over multiple cycles

Substrate vitality is what separates "OK grows" from "consistently exceptional grows."

The three variants explained

MGP Plus — Growth Promotion + Substrate Vitality

Best for: Cultivators who want the full package — both immediate growth boost AND long-term substrate health.

What it does:

• MGP (Mushroom Growth Promotion) microbes — beneficial strains that directly support mycelium expansion
• Substrate vitality components — broader microbial community for substrate health
• Combined effect: Faster spawn run + healthier multi-flush cycles

Use case: Standard cultivation where you want to optimize both speed AND consistency.

Application:

• Pre-inoculation: Add to substrate hydration water
• Between flushes: Add to dunking water for substrate revival
• Post-spawning: Surface application during early colonization

MGP Pure — Maximum Growth Promotion

Best for: Cultivators focused on rapid, vigorous growth of gourmet and medicinal species — oysters, lion's mane, shiitake, reishi.

What it does:

• High concentration of MGP microbes for maximum growth acceleration
• Streamlined formula focused on growth promotion specifically
• No substrate vitality components (use Just the Trich separately for that)

Use case: When you want maximum mycelium expansion speed — particularly useful for:

• Time-sensitive grows where you need fruits in the minimum cycle time
• Wood-loving species where the substrate has lower baseline biological activity
• Competition-grade cultivation where size and uniformity matter
• High-yield commercial production focused on volume

Application:

• Pre-inoculation: Most effective at this stage
• Heavy dosing for maximum effect
• Pair with Just the Trich for combined growth + vitality benefits

Just the Trich — Substrate Vitality Only

Best for: Cultivators who don't need growth promotion microbes but want substrate health support. Particularly useful when:

• You're already using a different growth-promotion product
• You want substrate vitality without competing microbial communities
• You're doing pre-pasteurized substrate work where growth promotion isn't the priority
• You want to separate the growth promotion variable from the substrate vitality variable in testing

What it does:

• Substrate vitality components only — no MGP microbes
• Supports the broader substrate microbiome without growth promotion microbes
• Compatible with any inoculant or growth promoter

Use case:

• Stack with another growth-promotion product
• Use alone for ongoing substrate maintenance between flushes
• For controlled testing of growth-promotion vs. vitality effects
• For commercial cultivation where the growth-promotion microbes are already established from prior batches

Application:

• Between flushes for substrate revival
• Post-flush re-hydration to support continued substrate productivity
• Stack with other growth promotion products without interaction concerns

How to choose between variants

| Your situation | Recommended variant |
|---|---|
| First-time Dr.Myc user, want full benefits | MGP Plus |
| Focused on fast growth (gourmets) | MGP Pure |
| Already use a different growth promoter, want vitality support | Just the Trich |
| Multi-flush cultivation focused on extended substrate life | MGP Plus |
| Multi-flush cultivation where growth speed is most important | MGP Pure |
| Commercial scale, well-established cultivation | MGP Pure or MGP Plus (depending on focus) |
| Genetics testing or experimentation | Just the Trich (cleanest control) |
| Wood-loving species cultivation | MGP Pure |
| Cubensis cultivation | MGP Plus or MGP Pure (both work) |
| Substrate quality concerns | Just the Trich |

If unsure: MGP Plus is the safe default for most home cultivators.

How Dr.Myc compares to other growth promotion approaches

| Approach | Pros | Cons |
|---|---|---|
| Dr.Myc Growth Promotion (this) | Proven formulation; multiple variants; specific to mushroom cultivation | Higher cost than DIY |
| Colorado Cultures Fungi Fuel | Multi-component blend; CC-branded; consistent | Different formulation philosophy |
| DIY microbial inoculants | Lowest cost | Quality variable; takes expertise |
| No growth promotion | No additional cost | Slower, less consistent grows |
| Synthetic substrate additives | Specific compounds | Risk of contamination from chemicals; some additives harmful to mycelium |

For serious home cultivators, Dr.Myc Growth Promotion is the premium growth-promotion option that consistently produces better results than DIY or skipping growth promotion entirely.

Use cases

First-time cultivators starting their cultivation journey

• Recommendation: Start with MGP Plus
• Reason: Get full benefits without overcomplicating
• Application: Add to substrate hydration water at recommended dose

Multi-tub cultivators wanting consistency

• Recommendation: MGP Plus or MGP Pure across all tubs

What this is NOT

• Not synthetic fertilizer. Dr.Myc products are biological — beneficial microbes and natural growth factors.
• Not a contamination cure. Already-contaminated substrates can't be saved by growth promotion. Use for healthy substrates.
• Not a substitute for proper sterile technique. Dr.Myc supplements good technique; doesn't replace it.
• Not for non-mushroom cultivation. Designed specifically for mushroom cultivation. May not be effective on plants.
• Not all variants are identical. Each variant has specific positioning. Choose deliberately.
• Not autoclave-safe. Microbial-based products are killed by autoclave temperatures (250°F+). Apply post-pasteurization for full effect.

Pairing with the Colorado Cultures lineup

A note on Dr.Myc vs. Colorado Cultures Fungi Fuel

Both products serve similar purposes. Comparing:

For most cultivators, either product works well. Dr.Myc's variant approach gives more options for specific use cases (gourmets vs. cubensis, growth focus vs. vitality focus). Fungi Fuel's single-product approach is simpler.

Trying both across separate cycles is a reasonable way to determine which works best for your specific cultivation conditions and species.

Storage and shelf life

• Storage temperature: Cool, dry location (50-77°F / 10-25°C)
• Avoid: Direct sunlight, freezing, heat above 95°F
• After opening: Refrigerate to extend life; use within 6-12 months
• Signs of degradation: Off odor, unusual color change, visible mold
