Note: This is the magical version of our jars, for the standard/gourmet mushroom version see miraclefarms.org
When preparing jars, even the slightest variation in PH can hinder growth. We heat, magnetically stir and blend all ingredients and then test and adjust the PH of every jar. Our jars are then pressure sterilized in our medical-grade autoclave for 60 minutes at 15psi. All work is done in a sterile lab in front of a laminar flow hood (see photos in this listing) wearing all necessary equipment, i.e. surgical rubber gloves, scrubs, Tyvek wrist sleeves, surgical face mask, etc.
We may not be the cheapest jars in town, but with our clear LC jars, you know you’re getting quality and peace of mind that your cultures will grow without the fear of contamination…and best of all, totally reusable!
