Product Description

The PF Tek: a recipe and method that revolutionized amateur mushroom cultivation. Here we have half pint wide mouth jars, filled with the traditional PF Tek mixture of organic brown rice flour, hardwood sawdust, vermiculite, and water. Our jars are guaranteed fresh and sterile and come with four cleanly drilled and taped holes in the lids for easy and fuss-free inoculation.

These wood supplemented jars are ideal for growing a variety of wood loving mushroom species, including: luminescent panellusshiitake, oyster, reishi, and lion's mane. The sawdust addition will aid in the production of larger, healthier mushrooms for a variety of mushroom species.

Unlike other suppliers, our jars are mixed using wide mouth half pint jars, the jar recommended in the original PF Tek. The resulting shorter, squatter cake is thought to be more productive for mushroom formation during the fruiting stage. Following the basic PF Tek recipe, clean bottled water is mixed with organic brown rice flour, hardwood sawdust, and grade 2 medium grain vermiculite. A dry vermiculite layer tops off the mixture. Although the original recipe didn't call for it, our jars are then sterilized using our steam and pressure sterilizers, allowing us to guarantee them free from contamination.

The jars are shipped with four cleanly drilled and taped holes in the inverted dome lid. The clear tape allows for easy, fuss-free inoculation. The process and methods for making your own PF Tek Jars is illustrated with great explanation and detail in the Let's Grow Mushrooms! - 2 DVD Set by Marc Keith.

This wood supplemented PF Tek recipe will support the mycelium growth of a wide variety of mushroom species. It makes a great basic fruiting cake for shiitake mushrooms. Try a variety of cultures in this substrate, or use the colonized cakes as spawn in wood chip beds for establishing outdoor mushroom garden patches!

History of the PF Tek: In the early 90's Robert McPherson, aka Professor Fanaticus, introduced the world to The classic PF Tek recipe for substrate preparation. The process revolutionized amateur mushroom cultivation, allowing easily accessed ingredients to be mixed and sterilized using commonly available equipment. Simple rice flour is mixed with vermiculite and water and loaded into half pint wide mouth jars. The jar mixture was able to be sterilized reasonably well using a large stock pot with boiling water.

Note to local customers: to ensure freshness, most of our sterilized substrates and media are prepared to order. As a result we do not stock these items on our shelves, or place them into cold storage. Rarely, we may have a handful left over from the day's run, but please call ahead of time to ensure we can prepare them for pickup.

Note to International customers: due to increased exposure and potential of longer transit times, we can not extend our standard replacement guarantee to customers receiving this product outside the USA. You may still place an order for and receive this product, but you will receive it "as is," without claim to replacement material should you experience contamination or failure.

Priced per jar, see above for quantity pricing information.

Made to order, usually ships within 2-5 days. While our PF Tek jars are guaranteed to arrive sterilized and free of contaminants, they are still somewhat perishable. Please use jars within 4 days of receiving your order. We are unable to offer replacements for unused jars after that time frame.
