Magnum Amazonian Magic Mushroom Grow Kit 2100ml – Premium Mycelium Bread for Bigger Flushes

The Magnum Amazonian Magic Mushroom Grow Kit 2100ml is a high-capacity, ready-to-fruit mycelium bread engineered for abundant, resilient flushes of Psilocybe cubensis Amazonian strain—ideal for both curious newcomers and experienced cultivators.

Struggling to get consistent results from your mushroom grow kits? You’re not alone. Many beginners start with tiny kits that dry out fast or produce just a handful of mushrooms, leaving you wondering if it’s even worth the effort.

That frustration compounds when you finally get a flush—only to realize it’s too small to share, too weak to feel the full spectrum of the experience, or worse, ruined by mold because the substrate couldn’t handle minor humidity swings. You end up wasting time, money, and precious enthusiasm.

Enter the Magnum Amazonian 2100ml kit: a game-changer in home cultivation. With nearly double the substrate volume of standard kits, it buffers against beginner mistakes, sustains longer fruiting cycles, and delivers noticeably larger harvests—so you can actually enjoy the full ceremonial or exploratory potential of your grow.

Why the Magnum Size Makes All the Difference for New Growers

If you’ve never grown mushrooms before, the last thing you need is a finicky, low-margin kit. The 2100ml format gives you breathing room—literally. More substrate means more moisture retention, more stable mycelium health, and a forgiving window for learning proper misting and fanning techniques.

• Extra substrate volume prevents premature drying during first flushes
• Clear, step-by-step instructions included (no guesswork)
• Pre-colonized and contamination-tested for peace of mind
• Perfect for learning the full lifecycle without pressure
• Compatible with basic home setups—no fancy gear needed

What Advanced Cultivators Love About This Amazonian Kit

Seasoned growers know that strain and substrate quality dictate yield potential. The Amazonian strain is prized for its fast colonization, thick stems, and dense caps—plus its resilience in varied conditions. Paired with a 2100ml nutrient-rich rye-based substrate, this kit is built for performance.

• High-yielding Amazonian genetics known for robust fruiting
• Larger substrate mass supports 3–4 flushes with proper care
• Ideal for experimenting with casing layers or monotub transfers
• Consistent mycelial vigor reduces contamination risk
• Great base for cloning or grain-to-grain expansion

Universal Advantages of the Magnum Amazonian 2100ml Kit

• Discreet, odorless during colonization—perfect for urban grows
• Ships fast and fresh from climate-controlled storage
• Legal for mycological and ethnobotanical study in the EU
• Includes humidity tent (mini greenhouse) for optimal pinning
• Optimized for 22–25°C ambient temps and 85–95% humidity
• Each kit is individually sealed and lab-inspected
• Supports sustainable exploration—no wild harvesting needed

Common Mistakes This Kit Helps You Avoid

Most failed grows come from preventable errors—not lack of skill. The Magnum format inherently reduces these risks by design.

• Over-misting: Larger substrate absorbs excess moisture better, reducing mold risk
• Under-harvesting: Bigger yields mean you won’t pick too early out of impatience
• Poor air exchange: Sturdier mycelium tolerates minor CO2 buildup during early pins
• Single-flush disappointment: 2100ml sustains multiple flushes, maximizing your effort
• Contamination panic: Healthy, dense mycelium outcompetes airborne invaders

Frequently Asked Questions

How long does it take to harvest from this kit?

Typically 7–14 days after initiating fruiting (cutting the bag and misting). First pins appear around day 5–7, with full maturity by day 10–14 depending on conditions.

Can I grow this kit without a humidity tent?

Technically yes, but yields will drop significantly. The included mini greenhouse maintains the 85%+ humidity needed for pinning. For best results, use it as directed.

Is this kit legal in my country?

This product contains mycelium and substrate only—no spores or fruiting bodies at time of sale. It’s sold strictly for mycological, ethnobotanical, or ornamental study. Check your local laws, but it’s fully compliant in most EU regions under these terms.

How many flushes can I expect?

Most users get 2–3 solid flushes. With careful harvesting and rehydration (cold shock + soak method), some report a fourth smaller flush.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of mushroom kits over the years, and the Magnum Amazonian 2100ml stands out for one reason: reliability. When I recommend it to friends new to cultivation, I tell them, “This one forgives your first mistakes.” The extra substrate is like training wheels—it keeps you upright while you learn humidity balance and harvest timing. For my own grows, I use it as a launchpad. After the second flush, I often transfer the spent cake into a monotub with a coco-coir casing layer to push for a third or fourth harvest. The Amazonian strain’s aggressive mycelium takes to this beautifully. Pro tip: don’t harvest all pins at once—leave a few small ones to “pull” nutrients for the next flush. And always, always wash your hands and spray with 70% isopropyl before handling. This kit’s size makes it worth the extra care.
