10 PRE-STERILIZED 1/2 Pint BRF+Vermiculite Mushroom Substrate "Jars"

ALL SUBSTRATE JARS GUARANTEED STERILE UPON DELIVERY.
NO PRESSURE COOKER REQUIRED.

You just inject the spores.

All substrate jars are made fresh TO ORDER.

Each substrate jar has 4 pre-drilled holes in their lid.

These are the holes you inject your spores through.

Each substrate jar is a mix of brown rice flour, vermiculite and water.

The ingredients are mixed thourougly to ensure even nutrient distribution.

Each is then topped off with a dry vermiculite layer.

The vermiculite layer is a filter to keep airborne contaminants out, while still allowing for gas exchange out of the holes in the lid.

"Jars" are made from PP5 Plastic (Pressure Cooker Safe Plastic)

If you have any questions about the substrate jars and/or the growing process please feel free to message me anytime.

Thank You.
