Warranty & Refund Policy

Within the first 30 days of placing your order we guarantee that your substrate product is free from defects or we will replace it and ship the replacement product for free. If the product has been already been used we will issue a store credit only for product purchase price minus a 20% processing fee. Shipping fees and sales tax are non-refundable. 

To file a claim please take at least 3 close up photos of the injection port and each bag or jar showing us the issue so we can review your claim.  We offer replacement products only on defective or damaged products. No need to return products.

Spawn Bag & Jar Tips

After injecting your bag or jar, give it a gentle shake. For bags, make sure any grains stuck in the upper portion are knocked down so they can colonize properly. There’s no need to break up the spawn during colonization unless you prefer to. If you choose to do so, wait until the bag or jar is roughly 50% colonized before mixing.

Organic Rye Berry Spawn Jars (Three-Pack) – Pre-Sterilized Grain Substrate with Injection Port & .22 µm Gas-Exchange Filter

Product Description
Unlock the next level of gourmet-grade mushroom cultivation with our meticulously engineered Organic Rye Berry Spawn Jars. Crafted at the intersection of chef-level precision and mycological insight, these three 32 oz Mason jars come pre-filled, pre-sterilized, and ready for inoculation—delivering a plug-and-play substrate solution that meets the rigour of professional-grade kitchens and cultivation labs alike.

Why This Spawn Jar Set Works

  • Each jar holds 1 lb of hydrated organic rye berries—fortified with food-grade calcium and sulfur—for improved grain integrity, enhanced moisture retention and optimal “bite” in your colonization phase.
  • A self-healing injection port paired with a .22 µm gas-exchange filter means you’re protected from contaminants while maintaining critical aerobic exchange—no extra prepping required.
  • Made-to-order and shipped only after sterilization ensures minimal shelf-time and maximum freshness. 
  • The three-jar pack offers both flexibility and economy—use all three at once for a large-scale spawn run, or stagger them for multiple rounds of cultivation without opening multiple bulk bags.

Performance You Can Trust
As a chef-owner turned mycologist, you understand that substrate cooking isn’t a “one-time setting”—it’s about grain age, absorption dynamics, sterilization rigour and ideal moisture equilibrium. With these jars you skip all that prep: the water content, conditioning and sterilization are managed for you factory-direct under controlled conditions. Simply inject ~2 cc of your chosen spore solution or liquid culture, swirl to distribute evenly, then incubate at your strain’s optimal temperature. Shroomability

Applications & Versatility

  • Ideal for professional and advanced amateur growers who demand consistency and high-yield results.
  • Perfect for spawning onto bulk substrates (e.g., sawdust, coir, coco-coir, wood chips) without the variability of “in-house” grain prep.
  • A smart choice for product developers or educators who need predictable, reproducible substrate runs without the labour overhead or equipment footprint of grain sterilization.

Unpacking the Benefits

  • Time-Savings & Labor Reduction: No need for soaking, simmering, loading jars, drilling lids or cleaning up grain-prep mess. You get “ready-to-go” performance straight out of the box.
  • Sterility Confidence: Much like a fine kitchen brigade relies on clean mise-en-place and tightly controlled temperatures, our jars are sterilized and sealed, with the added built-in safety of injection ports and filters.
  • Batch-to-Batch Consistency: When the substrate is consistent, your growth parameters become the only variable—just as a great chef uses standardized mise-en-place to focus on technique, not prep.
  • Scalable Growth: Whether you’re producing gourmet mushrooms for a fine-dining menu or scaling for retail, these jars offer a reliable spawn base that supports upscaling into larger systems.

Usage Instructions

  1. Sanitize your work-area and wear gloves/mask (each order includes a prep-kit).
  2. Inject ~2 cc of spore solution or liquid culture via the self-healing injection port.
  3. Gently swirl the jar to distribute the inoculum evenly at the grain surface.
  4. Incubate at the strain-specific temperature until full grain colonization is achieved.
  5. When the jar is fully white-colonized, it’s ready for transfer to your bulk substrate, casing layer or fruiting system.

Why Choose Us?
At Shroomability we marry three decades of high-end culinary experience with deep mycological know-how. Just like a chef masters thermal profiles and flavour development in rare meats and exotic grains, we master moisture content, sterilization precision and substrate architecture for mushrooms. The result? Substrates that perform, consistently and reliably.
