What do you think of this? Heating dry straw at 300' or two hours. Saving until you need it in a dry trash bag, inside of a tub. Adding distilled water when it is time to sprout.

What do you mean by saving it? I would wait until you had a plan before sterilizing the straw. If not, tie that bag up good.

Yeah. In a bag. Save it mabey for a week or two then use.

PASTEURIZE don't sterilize. Steep the straw in water @ 170 degrees for one hour. Sterilizing straw kills certain good micro organisms that will help fend off infection. Sterilization will cause a bacterial bloom..... contamination. Contaminated straw is a big, stinky mess that will require more time to clean up than it would to pasteurize it. Look up OT's straw tek.

Sterilized straw, well spawned in clean room conditions, colonizes and fruits just fine.
The problems occur when straw is neither pasteurized nor sterilized. Then you have real problems and nothing works.
To sterilize straw you need 15lbs steam for 45 minutes.
To pasteurize straw, the straw needs to be moist or wet and heated to temps between 160 - 180*F for a minimum of one hour.

3 of 4 straw casings of mine got cobweb mold.. I steeped straw at 170/175 for 2 hours... then split it up and innoc'd it with rye grain... 3 out of 4 shoebox sized casings of it got cobweb mold. Wonder what went wrong. What causes cobweb mold?

how often were you doing air exchanges ?
|Posted on Thursday, December 06, 2001 - 03:08 am:||
I appologize for my incorrect post. A guy grows a few good crops and thinks he knows everything. I've been humbled

hippie, the air exchanges have not really been done aside from opening it once a day to check on it. I was keeping the casing itself closed tight with a lid (same as i did for peat moss and worm poo casings with no problems) until it was overtaken by mycelium... but in the 2nd day I started noticing cob mold on it

I had cobweb problems on straw too which is why I experimented with more sterile procedures... Including sterilized straw and clean room spawning.
Interesting to note that as of late, Cobweb was the first contam to show up on leftover cooked rice that sat out... And it appeared uniformly in the leftover rice, pretty much the same way it it used to show up in straw beds before the spawn could get started.

Glad to see folks still experimenting with straw techniques... Keep on keeping on and the process will reward you handsomely....
Peace and good growing wishes from the old man...
Trust me, experience is priceless and if you learn the nuances of straw culture you'll never look back.... you will actually laugh at fruiting cakes and whatnot... not that there's anything wrong with the PF tek. It's perfect for newbies who want to see something grow, but if you are wanting larger more rewarding yields look to straw...

OT, thanks for the encouragement. I spent a fine summer enjoying fruits grown on dung outdoors, while experimenting with straw...and I gave up on straw. I'm now working with variations of pftek because cobweb and trichoderma killed every one of my strawbeds...your encouragement has given me a boost. I think I'll go ahead and work with the straw some more
|Posted on Friday, December 07, 2001 - 01:34 am:||
Agreed, OT. It took me 40 or so trays to get it right. I now use yer old worm poop tek to adjust the moisture of the straw.
I also PC my straw in big jars or bags. 15 psi for 45 min or more.
Since doing this and using a 50/50 w/ lots of lime casing, I have 0 contam probs...have not seen the mean green in months.
Thanks for all the inspiration, OT---fishy1

I thought that sterilizing straw is a bad idea? I thought that pasteurizing it is the best idea? Am I wrong in this? Should I just be pressure cooking my straw and not bothering with the guesswork of pasteurizing it?

Hell yea' OT. Bringing the straw teks to this board has put you in the Pantheon for good.
For anyone out there who's still on the fence:
Once you have mastered cakes, I highly recommend trying straw. For the PF tek-ker, it is *the* best next step, IMHO.
Thanks OT for sharing your vast experience and wisdom.
