Pan de Setas Costa Rica – Premium Mycelium Substrate Block for Home Growers

Pan de Setas Costa Rica is a premium, pre-colonized mycelium substrate block crafted for effortless home mushroom cultivation—no sterile lab, no guesswork, just consistent flushes of fresh mushrooms from a clean, ready-to-fruit base.

Ever tried growing mushrooms only to end up with mold, weak pins, or nothing at all? You’re not alone. Most DIY substrates are either under-hydrated, improperly pasteurized, or packed in flimsy bags that invite contamination the moment you open them. The result? Wasted time, money, and that sinking feeling when your grow fails before it even starts.

That frustration ends here. Pan de Setas Costa Rica arrives fully colonized, pasteurized, and sealed in a high-grade breathable bag with a 2-micron filter patch—so your mycelium stays protected until you’re ready to fruit. Just cut, mist, and watch your mushrooms thrive.

Why This Block Outperforms Homemade or Generic Substrates

Unlike amateur mixes that rely on guesswork, Pan de Setas Costa Rica uses a proven blend of hardwood sawdust, coco coir, vermiculite, and gypsum—hydrated to field capacity and pasteurized under industrial conditions (2 hours at 17 psi). This eliminates competitors like bacteria and wild molds, giving your mycelium a clean runway to dominate and fruit vigorously. The thick, durable bag prevents punctures and maintains humidity better than thin alternatives, while the integrated filter ensures fresh air exchange without contamination.

Key Features You’ll Notice from the Very First Use

• Pasteurized & pre-colonized – Skip the sterilization step; your block is ready to fruit straight out of the box.
• Optimal hydration – Pre-moistened to field capacity so mycelium spreads fast and pins form evenly.
• High-grade filter patch (2-micron) – Allows gas exchange while blocking airborne contaminants.
• Dense, uniform mycelium – Full colonization means faster, more abundant flushes.
• Compact & discreet – Fits easily in a monotub, grow tent, or even a modified storage bin.
• Made with organic supplements – Coco coir and vermiculite boost water retention and nutrient availability.

Who This Product Is Especially Interesting For

Whether you’re just starting out or you’ve had mixed results with other kits, Pan de Setas Costa Rica is engineered for reliability and yield. It’s ideal for:

• Beginners who want a foolproof entry into mushroom cultivation without investing in lab gear.
• Experienced growers looking for a clean, high-performance substrate to scale their monotub or bag grows.
• Urban cultivators needing a compact, low-odor, and discreet solution for small spaces.
• Anyone prioritizing consistent flushes and maximum yield per block.

How to Integrate It Into Your Routine Without Overcomplicating Things

Using Pan de Setas Costa Rica couldn’t be simpler. Once your block arrives, just cut an X-shaped slit (about 2–3 inches wide) in the bag where the mycelium is thickest. Place it in a humid environment (like a monotub setup or a humidity tent), mist the exposed surface 2–3 times daily with distilled or boiled water, and provide indirect light. Within 7–14 days, you’ll see pins form. Harvest when caps begin to flatten but before they fully open for peak potency and flavor. After the first flush, let the block rest for 7–10 days, rehydrate lightly if needed, and repeat—most blocks yield 2–3 solid flushes.

Frequently Asked Questions

Do I need a sterile flow hood to use this block?

No! Pan de Setas Costa Rica is fully colonized and sealed in a contamination-resistant bag. Just work in a clean area (wipe surfaces with 70% isopropyl alcohol) and avoid excessive handling.

What mushroom strains work best with this substrate?

While the block comes pre-colonized (strain-specific versions may vary), it’s formulated for lignin-loving species like Psilocybe cubensis, Lion’s Mane, or Oyster mushrooms. Always confirm the strain at purchase.

How long does the block last before fruiting?

Use within 2–3 weeks of arrival for best results. Store unopened blocks in a cool, dark place (not refrigerated) to maintain vitality.

Can I reuse the block after harvesting?

Yes! After each flush, let the block rest, rehydrate lightly by misting, and maintain humidity. Most users get 2–3 harvests before yields drop significantly.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of substrate blocks over the years—some too dry, others contaminated out of the box. Pan de Setas Costa Rica stands out because it’s consistently dense, fully white with mycelium, and fruits fast. I used it last month in a simple monotub setup in my closet, and within 10 days I had thick pins forming. The first flush was so heavy I could barely lift the block! What I love most is the reliability: no guesswork on hydration, no waiting weeks for colonization. It’s ready to go. I’d recommend it to anyone tired of finicky kits or failed grows. Just cut, mist, and chill—your mushrooms will do the rest.
