Pf tek substrate jars also known as brf tek or brown rice flour jars have been a staple in the mushroom growers pantry for around 2 decades now. We use ball canning jars.

Each one of our jars has two pre-drilled holes in the lid and a top dry layer of vermiculite to add a dry filter between the lid and the substrate to help fight against contaminates. All independent test samples reported to have shown to start colonizing between 4-7 days after injection with spore syringe at incubation temperatures of 78f 80f.

All jars are topped off with aluminum foil to help stop contaminants from getting into the 2 inoculation holes in the lid. Want bigger & faster yields. For higher yields check out our pf mycotek jars that incorporates our mycomash mushroom bulking additive. The first 100% natural mushroom bulking additive on the market. When mycomash added to your pf tek or grain spawn jar or bag recipe it can increase yields in pf tek jars by 50-75% and increase colonization in your grain spawn by up to 3 weeks.

Be sure to colonize following all sterilization methods when inoculating these jars. Remember, these jars are the perfect environment for fungal spores, mold spores, to colonize. Green house mold is most prevalent and 1 billion mold spores can fit on the tip of a pen. So, when you think you're safe, you're not. Each pack of pf tek substrate jars will come with instructions outlining multiple methods to inoculate and safety tips for sterilization.

If you follow our step by step process, you will have 100% success. If you miss 1 step, you cannot guarantee success. Remember, these should be done in lab quality standards for cleanliness. Don't be surprised if you fail your first time.
