Sawdust Question...
    #14924844 - 08/15/11 08:34 AM (12 years, 6 months ago)

I have a great source for hardwood sawdust from a planer. It is mostly small particles with small to medium shavings mixed throughout. My question is.. Will the shavings act enough like wood chips oxygenating the substrate? If so, How would I change Mark's recipe (Lets Grow Mushrooms; Sawdust and Wood chips chapter)to compensate the difference?

Thanks in advance..

I am curious as well.
I have a good local source for organic hardwood sawdust.
$50/lb too! :dancer:

I am also looking into getting a composter unit and using some sawdust as part of that... Heard some good things.
Thoughts on that?

I wouldn't pay too much. I am getting it for free at a cabinet making shop. I went twice and got about 600 lbs. I can get more but I need to make a dent in what I already have. As far as composting sawdust... I believe it needs to be mixed with other carbons to make the 30:1 c/n ratio. There is a problem with using sawdust exclusively.
(I can't remember exactly. I will try to research it again.)

I sure hope you mean 50 lbs for $1.

You can use sawdust by itself without wood chips. If it feels too fine, cut it with some vermiculite to fluff it up a bit.

Go easy VV.  I am sure that archivist is right.  (nothing else makes sense really)

As to unsupplemented sawdust, it works just fine, with all of the edible
strains that I have tried.  (Oysters, Shitake, and Namaeko)

I used it because Lipa suggested a water/pellet ratio that allowed me to
just dump boiling water into the sack, a la coir tek, without pasteurizing
the result.  I think that the grains themselves represented a supplement
in a way though.  I got mad shitake fruits.

Take care,

JD

To the OP, as said just skip the chips and use sawdust.  Course sawdust is what you want.  Often the very fine flour-like sawdust from furniture shops performs poorly.  It sounds like you have the right stuff.  If you can get it from a sawmill or someone who uses a chain saw, it's perfect.

You can often buy wood pellet fuel (basically just compressed hardwood sawdust) for around the same price.  I recently bought a 40 lb bag of pellets for $4 at my local hardware store.  The only thing is that they're seasonal items and stock runs pretty low during the summer.  It took a bit of searching before I found some.

I found a place that will sell me 40lb bags year round, and after hearing
that I am using them to grow shiitake they even stated they could make
custom batches for me, letting me choose such factors as type of hardwood
used, added bark %, moisture content, etc etc.

When you put in the time, research and effort you will be amazed at what
you can find.

LMAO!  :lmao:  That is an amazing arrangement.  Congrats bro!

Lipa saw the pellets that I used and thought that they looked to be
at least part hardwood.  I am lucky too....but not that lucky. ;0)

Take care,

Another source for sawdust that I feel's being over-looked is your local saw mill(s).  My sawdust is had from a local saw mill at all I pack into the bed of my pick-up for FREE.

I like to supplement sawdust mediums with gypsum and/or brown rice flour (I use instead of brown rice flour, rice bran) at 2% of EACH by volume of dry saw dust and, add shredded wheat straw (shredded into 1-2 inch pieces), as well as medium grade vermiculite.  EACH at 20% by volume of dry sawdust for varied sources of nutrition available to the mycelium during colonization, serving also as a means of "stretching" out the sawdust before hydrating, then pasteurizing.  The wheat straw is pasteurized in a lime bath, separately from the other materials before being mixed, then inoculated.

About the wood chips, I agree with the other 2 other posters above.  Leave them out.  I'v noticed that when woodchips are added to sterile sawdust mediums, the sawdust colonizes faster then the woodchips and the woodchips tend to dry out before the myce. can fully colonize them.  This opens a vector for the contamination of any invader spore(s) that lands on the dehydrated, un-colonized woodchips.

Take it you live in a place that doesn't have a sawmill?  I'm sure Dallas, Texas has a few. :wink:
