What I have done, and has seem to work the best is to use autoclavable filter patch bags with a mix of autoclaved saw dust and the dowel rods. I inoculate that with rye grain. The oysters colonize fast as does ganoderma. Grifola frondosa is slower, and Shitake in between. I have also inoculated straight dowels and I liked the sawdust - dowel mix better. Usually, the dowels are twice as long as you need so I soak mine before autoclaving and cut them in half.

So far I have had the oysters fruiting but the weather has been cold so not alot of growth, but bunch primordia! It is getting warm this weekend so I think things will pop soon. Slugs and squirels like to eat / molest your fruit bodies. Fuckers.

Thaks for sharing. So after soaking do you add any more water with the bags when you PC the dowls? Also at what PSI and how long do you PC it?..........peace

If I am doing just dowels than I do not use anymore water. If I use a sawdust-dowel mix I weigh the sawdust out in the bags (taking a tare for the bags) and I add water to about 65% by weight, then I add the soaked dowels, PC at 16 psi for 1 hour.

I tried this a couple of times. I noticed that wood dowels that were soaked for a week colonized much faster then the ones that were soaked for a day or two. I pressure cooked them in polypropylene bags with tyvek filter patch for 3h and inoculated with grain spawn.
I didn't add water in the bags.

Yeah, yeah, Anno is right. Heating the dowels does help them take up water.

This might not work as well if you do big batches, but for the number of dowels required for a few big logs in the yard this is more than sufficient:

No pressure cooking, just a good hot soak or two. . .has worked for shiitake and reishi without a hitch so far. The others' methods are certainly better and more sure-fire, especially when doing bags of dowels; but this is pretty nice for ease and speed.

That's interesting. I seems that dowels are hard to contaminate.
About longer soaking time... I was soaking dowels and I prepared a part of them after one day and had no time to use the rest. When I inoculated them after one week of soaking they seemed to colonize much better and faster then the first. I will make more trials...

so hot water definitely helps water uptake.
how bout boiling the dowels as partial sterilization AND to achieve proper moisture?
anyone ever just boiled them?
:laugh:

My impression is that water uptake isn't too tough. . .it can be as simple as letting them sit in room temperature water. . .*long enough*. After they sink, not much more H2O uptake will occur. The other thing that plays a role in dowel success is the actual container that they are incubated in. If it's too big/too spacious, the dowels can dry out during colonization.
Just boiling them would work, I'm sure. . .steeping in hot water appears to be quite sufficient as well.
Something I learned over the past month or so is that dowels are very tough to contaminate.

I just recieved my 100o dowels from the company that you suggested Suntzu. Thanks for the tip.
