pastuerizing straw
    #2991656 - 08/11/04 05:00 PM (13 years, 12 days ago)

i was wondering if anyone knows of a way other than putting the straw in water and cooking at 170 degrees to pasuerize it. I heard you can just stick it in the oven? It would be harder for me to find a big pot to put on the stove, but i have a big metal basin that i could throw right in the oven.

I have pasteurized straw in the oven using an oven bag. The problem with doing it in the oven is keeping the temp right. You don't want the heat to exceed 170(F) as this will fuck things up. So just make sure you can keep the temp at around 150/170 but not over 170.

:goodluck:

sterilize and pasteurize are totally different. I wouldn't suggest sterilizing straw as once it is introduced to air it will contam right away. so pasteurize it and the contams will not germinate for 2 pluss weeks.

be clean thats all ,you do not need that much the benifical bacteria,and if you sterialize do no run around 27 c slow down to 20 c 's mycellium can fight with the bacterias at these temps and in generaly wins.

or buy your compost from ebay vs...

Dont sterilize it ! I dont know what the prob, heat up the metal basin on the hot plates. But you can also put it in the oven. I see a pictural at the Nook i think. Use an meat thermometer that you can check the temp. Put lime in the water ( 1/2 cup per 5-7 liter ) that will make the ph very high and you dont have troubles with contams. No worry about the high ph level, your shrooms grow.


good luck,,

that will decreases your yield.
so as a result if you don t buy your compost or if your mum will upset about the straw in the oven you can do it in pc.
i use that pc straw shit for a long time.the oven looks like to me like how you see.yes pastour is better but as i said it works for me from a long time.i did all my pan shit in pc and you really can t believe about my yields.

my mom doesnt have a problem with me using the oven or whatever, i just think it would be easier (for me) to throw it in the oven. I dont want to buy my compost... i just like doing things myself. As for the lime juice... seems there are 2 oppinions? Is the high ph just to ward of contams, or is it sapost to help the mushrooms grow? (or make them more potent) also can lemon juice be subbed for lime? fugu sais it will decrease my yeild and i dont want that

lol i think he means limestone...Anyways i have this question as well...I thought you can just put the hay/straw in a rubbermaid tub and have 4 big pots of boiling water ready and put the boiling water on the straw and let it sit for 15 min. I can be wrong and have never attempted but as well i am going too and good luck.

Lime is a neutral element that will stabilize the pH at 7.0 +/-. It will help from the myc's slightly acidic metabolic wastes from dropping the casing/substrates pH into the range that trich thrives in (acidic) just so your on the same page bro :wink:

ive done plenty of pasteurizing with just lime and water no heat and had no worrys but it was only using oyster spawn i did read somewhere that you could use the lime method with cubies , from memory i think it was on the erowid site

@ dcyans I read the stuff about the high ph at this thread:

http://www.mycotopia.net/discus/messages/5/30183.html?1059589094

"Use ? cup of hydrated lime for this recipe which uses 14-16 gallons of water. Be sure to stir the lime into the water very well. If you?re making a larger or smaller batch, adjust the lime accordingly. This will give the water a ph of 12-13 before the straw is added. This radical swing in ph, along with the heat will render the contaminants inactive for a couple of weeks. "

I work now nearly 1 year this way and really never had contams.
The last time i forget the lime and all contamed.

Hydrated lime IS hot no doubt! Very little goes a long way but it doesn't last, lime on the other hand like oyster shell flour or powderized eggshell will last a long time. My question is what is the pH after the straw soak i'm thinking close to neutral as myc won't grow in a basic/acidic environment. You sound like you've had nothing but success with this method so I'm not going to kick it one bit and may even try it some time in the future. :wink: GL and may your flushes proliferate!
