Thai Mushroom Grow Kit – Psilocybe Cubensis Samuiensis, 1200ml Mycelium, 3–5 Harvests

Meet the Thai Mushroom Grow Kit: a complete, ready-to-fruit cultivation system featuring Psilocybe Cubensis Samuiensis mycelium, designed for predictable harvests and hassle-free growing from day one.

Ever started a grow only to watch it stall, dry out, or produce one tiny flush and then quit? You’re not alone—most kits promise abundance but deliver inconsistency, leaving you guessing what went wrong.

That uncertainty kills your confidence. You waste time troubleshooting instead of enjoying the process, and you start doubting whether your setup, your timing, or the kit itself is to blame. It’s frustrating when you’ve done everything “right” but still get unpredictable results.

That’s why this Thai kit is different. With 1200ml of fully colonized, high-vigor mycelium and a precision-engineered grow bag with microfilters, it’s built for stability. Just maintain 22–24°C and 60–80% humidity, and you’ll trigger consistent fruiting—no guesswork needed.

Why This Kit Delivers Repeatable, Trustworthy Harvests

The secret lies in its robust Samuiensis genetics and optimized substrate volume. Originating from Thailand’s humid Gulf coast, this strain thrives in stable, warm environments—exactly what this kit replicates. The 1200ml substrate provides ample nutrition for multiple flushes, while the dual microfilter bag ensures ideal gas exchange without contamination risk. Unlike flimsy alternatives, this setup maintains internal conditions so you don’t have to constantly intervene.

Key Factors That Influence Your Results (and How This Kit Helps You Control Them)

• Temperature stability: The kit performs best at 22–24°C—use a heat mat from our Smartshop if your space runs cool.
• Humidity management: Mist the inside of the bag (not the substrate!) with a spray bottle to maintain 60–80% RH—no overwatering needed.
• Air exchange: Microfilters allow passive CO₂/O₂ exchange, eliminating the need for manual fanning that risks contamination.
• Light exposure: Indirect ambient light is sufficient; no grow lights required, making it perfect for discreet home cultivation.
• Harvest timing: Pick mushrooms just before the veil breaks for maximum potency and to encourage subsequent flushes.
• Rehydration between flushes: After harvest, soak the substrate block in cold water for 24 hours to reset hydration—this kit’s structure holds up perfectly to this step.

Your Step-by-Step Routine for Consistent Success

1. Unbox and inspect: Ensure the mycelium is fully white and the bag is sealed.
2. Place in a warm, indirect-light spot: Ideal range is 22–24°C (72–75°F).
3. Mist the bag interior daily: Use distilled or boiled-cooled water to maintain humidity.
4. Wait 15–20 days: Tiny pins will emerge—resist the urge to open the bag.
5. Harvest at peak maturity: When caps begin to flatten but before spores drop.
6. Rehydrate for next flush: Submerge the block in cold water for 24 hours, then return to the bag.
7. Repeat: Expect 3–5 total flushes over 2–3 months with proper care.

Benefits of Predictable, Consistent Cultivation

• Build real confidence in your growing skills—no more second-guessing.
• Maximize yield from every kit, reducing waste and cost per gram.
• Learn faster by observing clear cause-and-effect in your environment.
• Enjoy the full lifecycle—from pinning to harvest—without stress or surprises.
• Feel in control of your experience, from first flush to final harvest.

Frequently Asked Questions

What if I don’t see pins after 20 days?

Check your temperature—it’s likely below 22°C. Move the kit to a warmer spot or use a heat mat. Patience is key; some flushes take up to 25 days.

Can I grow this kit outside a mini greenhouse?

Yes, but only if your room naturally maintains 60–80% humidity. In dry climates, a mini greenhouse setup is highly recommended for consistent results.

How do I know I’m harvesting at the right time?

Look for caps that are starting to open but still have a slight curve. If the veil (thin membrane under the cap) is intact or just beginning to tear, it’s perfect.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of mushroom kits over the years, and the Thai strain stands out for its resilience and rhythm. What I love is how it *tells* you what it needs—when humidity dips, pinning slows; when it’s just right, you get a flush so uniform it looks cloned. I keep mine on a shelf in my office (with a discreet humidity tent!) at a steady 23°C, misting once a day. My first flush came on day 17, and after a 24-hour cold soak, flush two was even heavier. The stems are slender, the caps a gorgeous caramel-orange, and the energy is bright but grounded—perfect for microdosing or mindful exploration. Pro tip: label your kit with the start date and note flush weights. You’ll quickly dial in your personal sweet spot.
