Oysters on Softwood Sawdust + Straw 1
#23488149 - 07/29/16 03:06 AM (7 years, 5 months ago) |

Going to try a little experiment of using softwood and straw. I found a university study which documents near 100% BE with softwood sawdust and straw 60/40.
I am going to go over and buy a yard of sawdust in Eugene for $18 and give this a trial. Not going with the Phoenix Oyster. Just going with the good old Aloha PL strain.
I am going to push out the essential oils and soften the sawdust by boiling it aggressively for a hour and a half. I have everything setup already. I have a stainless steel tank which I was using to boil small logs.
Initial ratio I will be testing will be 70/30 sawdust/straw with 10% grain spawn. Going for fast aggressive spawn run. Anyone ever done this or have any comments?
Hardwood sawdust is impossible to source...

I reduced ten pounds of straw with a large Rubbermaid and a weedeater with a metal brushing blade. How does this size look?

It was quite entertaining... The arcs of shredded straw flying up into the air. I have a high CC weedeater normally used for clearing entire blackberry patches which has what looks like a lawnmower blade on the end, except the tips of the blade are curved down toward the ground. It will chew through ten pounds of straw within five minutes... Actually, chewing through a pound of straw only takes ten seconds, but loading the rubbermaid takes time.

Could be finer, should work alright though.

I was considering it, but I have not worked with them, and I don't like what I have heard about the bad shelf life and etc...
Maybe someone can try to sell me on the Aloha AM-G8 Strain... They look good in their picture, but I dunno!

Tempting, but I love the PL Strain. Customers love it too.

Oh didn't know they had a shorter shelf life? Maybe doing a few with Phoenix just to compare the BE with PL? I'd be interested to the difference since Phoenix love softwood

Got a yard and a half softwood sawdust for $27. Dry weight estimated at 500lb based upon estimated 35% water content. Added 2% lime by dry weight and wetted it down and covered it with plastic for fermentation. Bought 100 pounds of this lime for $11.90.
The sawdust is a little more fine than optimal, but it should work fine with half straw.

You want the end water content around 50% you should be able to barely get a drop out with a tight squeeze.i would put some wheat bran @ 20% in there too and maybe some nitrogen organic fertilizer like chicken manure around 3-4%

I have certified organic composted chicken manure. Is that to accelerate fermentation?
I don't want to risk too rich a sub, so I'm not going to add bran.

Chicken manure will slow down fermenting. The extra nutes with speed ip colonized parts and increase the heat during that time. How are you cooking this system. If pasteurization id avoid yeast production. If sterilizing then you may want to make a starter with wine yeast then divide that into ten more starters then two dayz you pour that over the sub.

Sub will be boiled for an hour and dried to moisture content steaming hot and in the sun before spawning. Straw will be boiled first, then sawdust separately. I want to leech every last bit of remaining aromatic oil out of the softwood sawdust I can.
Wine yeast will work for fermenting wood??? Huh... I have plenty of wine yeast I use to make hard cider. The information I found on wood fermentation says this process should take around 40 days in these warm summer temperatures. However, I am going to start using the sawdust in small batches even before then, but it will be boiled for an hour and a half.
