Mexican Magic Mushroom Grow Kit – 1200cc Fully Colonized Mycelium Box

The Mexican Magic Mushroom Grow Kit is a ready-to-fruit 1200cc mycelium box that lets you cultivate one of the most legendary Psilocybe cubensis strains—known for its gentle effects, reliable growth, and deep cultural roots among the Aztecs.

Ever started a grow only to get unpredictable flushes, weak yields, or confusing results that leave you guessing what went wrong?

That inconsistency kills your confidence. You waste time troubleshooting instead of enjoying the process, and you never quite know if your next harvest will match your last—or if you’re even doing it right.

This 100% mycelium kit solves that. Fully colonized from day one, it delivers consistent, repeatable flushes with minimal guesswork—so you can focus on the experience, not the stress.

Why the Mexican strain gives you dependable, beginner-friendly results

The Mexican strain isn’t just historic—it’s naturally stable. Its genetics favor steady colonization and uniform pinning, meaning your mushrooms grow evenly and respond predictably to care. Because the entire 1200cc substrate is already packed with active mycelium, you skip the fragile colonization phase where most failures happen. First pins often appear within 10–14 days, and the strain’s mild potency (rated 2.5/5) makes it forgiving for new growers who want a clear, cheerful journey without overwhelming intensity.

Key factors that affect your harvest—and how this kit keeps them under control

• Substrate consistency: Pre-colonized 100% rye and perlite mix ensures even moisture retention and nutrient distribution—no dry pockets or soggy zones.
• Temperature stability: Thrives in a steady 20–25°C range, common in most homes—no need for complex climate gear.
• Humidity management: The included grow bag creates a microclimate that maintains ideal humidity with just daily air exchange.
• Flush timing: Cold-water rehydration after each harvest resets the mycelium reliably, triggering the next flush on schedule.
• Light exposure: Only indirect light is needed—no special lamps or timers required.
• Storage before use: If you can’t start immediately, refrigeration (2–8°C) pauses development without damaging the mycelium.

Your simple routine for consistent flushes every time

1. Unbox and inspect: Check that the mycelium is white and fragrant—no green or black spots.
2. Soak and drain: Submerge the grow box in cold water for 24 hours, then drain thoroughly.
3. Place in grow bag: Put the box inside the included bag, fold the top loosely, and position in indirect light.
4. Ventilate daily: Open the bag for 30–60 seconds each day to refresh CO₂ levels.
5. Harvest at peak: Pick mushrooms just before the veils under the caps begin to tear.
6. Rehydrate between flushes: After harvest, soak again for 12–24 hours to reactivate the mycelium.
7. Track your results: Note temperature, flush timing, and yield to refine your next cycle.

What consistency really gives you

• Confidence that your setup works—no second-guessing your technique.
• Less wasted substrate and fewer failed attempts.
• Faster learning curve: you see clear cause-and-effect from your actions.
• The freedom to plan sessions or share harvests, knowing what to expect.
• A deeper connection to the process—because you’re not fighting unpredictability.

Frequently Asked Questions

What if my first flush is smaller than expected?

Don’t panic! The first flush is often modest. Ensure you’re ventilating daily and keeping temps stable. The second and third flushes are usually the heaviest—especially with the Mexican strain’s reliable rebound.

How do I know I’m rehydrating correctly between flushes?

Submerge the entire grow box in cold, clean water for 12–24 hours, then drain completely. The substrate should feel heavy but not dripping. Over-soaking can suffocate the mycelium, so avoid exceeding 24 hours.

Can I grow this kit alongside other strains?

Absolutely! The Mexican strain’s mild nature makes it a great companion to stronger varieties like Golden Teacher or McKennaii. Just keep each kit in its own grow bag to prevent cross-contamination.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of grow kits over the years, and the Mexican strain remains my go-to for reliability. There’s something deeply satisfying about watching those slender stems and conical caps emerge right on schedule—especially when you’re introducing someone to cultivation for the first time. I keep one kit cycling in my closet year-round; I start a new flush every three weeks, dry the surplus, and always have a gentle, mood-lifting option ready for chill evenings. What I love most is how forgiving it is: even if I forget a day of ventilation, it bounces back. Compared to finicky strains that demand perfect conditions, the Mexican feels like a trusted friend—consistent, cheerful, and always there when you need it.
