DIETZ FARM MUSHROOMSSequim Washington
the site of the inadvertent creation of
Sequim Terra Preta
Lowell and Audree Dietz do Carpentry in Sequim.
Lowell's hobby is mushroom cultivation.
This has become a source of income.
The photo on the left is a plastic column of barley straw
that has been shredded, cooked and inoculated with
grain spawn. The mushroom is Pleurotus columbinus
also known as "Blue Cap Oyster Mushroom".
This mushroom is possibly the worlds best pizza mushroom.
Our fresh mushrooms are now available at
This site contains several pages to help beginning mushroom cultivators:
Grow Mushrooms At Home! has mushroom recipes and information about an amateur mushroom cultivators' group.
The Pink Oyster Mushroom page has instructions for growing mushrooms on growing kits you purchased.
How to make mushroom growing straw blocks is a page for cultivators who want to make their own growing kits.
You may view or print the one page sheet MUSHROOM KIT FAQS that we use at the Pacific Northwest Mushroom Festival in Lacey.
Successful growers will appreciate our MUSHROOM RECIPES page.
If you need dehydrated mushrooms and can't dry them yourself, we can deliver fresh mushrooms to a processor.
You may purchase them from the processor. There are two businesses in Sequim with inspected kitchens and
processors licenses who are willing to do this. Current demand for fresh mushrooms exceeds our ability to supply them.
We hope to increase production so we can sell mushrooms retail to the public. We have growing kits for sale:
Blue cap oyster mushroom
Tree Oyster mushroom
Pink Oyster mushroom.
We use a CARBON NEGATIVE ENERGY SOURCE here on the mushroom farm. The main hardware is a top load up draft furnace. It is known by initials: t.l.u.d.
We call it a
which we pronounce:
Tee - lud
"Tee" rhymes with "we"; "lud" rhymes with "bud"
|The t-lud works by
mixing smoke from air starved fire with pre-heated
air. The inner cylinder holds
wood. Only 20% of the furnace's air is
allowed to enter this primary combustion
chamber. 80% is channeled between the
steel and concrete cylinders, where it is
pre-heated before being mixed with the smoky
This is the t-lud's nozzle. It is held about 8" above the the primary air cylinder by 1/2" re-bars that protrude inside the concrete outer cylinder. This allows the 80% of the air to mix at the top of the primary combustion area.
This view shows the underside of the nozzle and the shell that becomes the front of the concrete cylinder.
This is charcoal generated from one burn.
This by-product may be used to grill steak.
If not, it can be used to make bio-char.
