Experience the magic of growing your own Cordyceps mushrooms with our Vented Screw Lid Jars

The 750ml Autoclavable Polypropylene (PP) Bottle is the “Goldilocks” of fungal cultivation. While maintaining the same 100mm wide-bore as its larger counterpart, the 132mm height is specifically optimized to prevent the CO2 “pooling” effect. This makes it the premier choice for Cordyceps militaris (CM) cultivation, where surface-level gas exchange is critical for vibrant stroma development.

Following our KISS (Keep It Simple & Stupid) philosophy, this bottle features a non-sealing, petri-style screw lid. This “flush-joint” design provides a natural barrier against contaminants while allowing the substrate to breathe freely without the need for additional filters—though the 20mm ePTFE filter patches can be added for high-risk environments.

Why the 750ml Bottle Wins:

• Optimized Geometry: The shorter 132mm profile ensures oxygen reaches the substrate surface, solving the “CO2 trap” issues seen in taller vessels.

• Full-Bore Wide Mouth (100mm): Straight-sided design with no tapered neck makes substrate filling and harvesting effortless.

• Transparent Clarity: Both bottle and lid are transparent, allowing crucial light entry for Cordyceps pigment production and easy monitoring of colonization.

• Vented Screw Lid: The coarse-thread lid mimics a Petri dish environment, ensuring safe pressure equalization during autoclaving (up to 126°C) and natural gas exchange during growth.

• Industrial Grade: Made from thick, virgin PP that resists breakage, chemicals, and repeated sterilization cycles.

Specifications:
