Collection: Sterile Mushroom Grain Spawn Injector Port Bags

✔ A Superior Result - We use temperature probes to monitor core bag temperature during sterilization to verify that we reach the correct time/temperature targets.

✔ Consistency Everytime - We ensure the grain is perfectly hydrated for rapid colonization 

✔ Sealed Before Sterilizing - Through our proprietary process, we seal the bags before sterilization to ensure no contamination. Shelf-stable food products are made the same way, which guarantees product integrity.

✔ Meticulous Attention To Detail - We hand-fill every bag, carefully packing the ingredients and neatly folding the bag. We place these in a perfect-size box and protective liner bag for further protection.

✔ Highest Quality Ingredients - We source local organic ingredients from USA businesses and prepare them in-house to ensure consistency in every batch.
