Re: Avoiding contamination during spawning to coir. [Re: TranscendingLife]

One more thing if you don't mind. So how many quart jars to pasteurize a brick of coir and 2 quarts of verm, and the 5 quarts of water? It seems like i t would take a lot... I heard of the pillow case method... Would that be more efficient?

And how can I go about pasteurizing with a 23 at pressure cooker? What temps am I looking for and how long? I heard around 150. I was under the impression that boiling water is what was used to pasteurize, but boiling is 212 right?

Would I manage to fit all the sub into 7 jars (7 is the max it can hold) and pasteurize in my PC vessel? Or would I be better of hydrating all my substrate, putting it in a pillow case, then put that in the pressure cooker with water at about 150 degrees? Not used to dealing with so much substrate outside of a bucket.

Thanks

You can things other than quart jars. I wouldn't use a pillowcase though just because IMO it's easier to raise the moisture content to the right amount than dry it to the right amount, which is what you'd have to do if you used a pillowcase since your substrate will get completely drenched in the process.

Oven bag or if you have any empty spawn bags you could use one of those.

alright. so put it all in an oven bag or two and put in pasteurization bath at 150~ for an hour and a half?

No, just in some water in a pot on the stove. You'll need a cooking thermometer. Heat it until the center of the substrate reaches 150-160F and then try to keep it in that range for a full hour. In particular you don't want it to get above 170F.

Possibly because you have the lid upside down.

I cant really see this being an issue... what are your reasons for thinking this? genuine curiosity.

It's the right way. Filter should be on the outside. Which side of the lid has the filter on it isn't really critical. It's easier to remove with the rubber side up so a lot of do it like that.

the orientation of the lid doesnt matter.  With PF tek its best to put them upside down to get them off.  With grain it don't matter if your a top or a bottom.

I would think that using the rubber side against the glass, you will get a seal that contams can't get by.

It'll make a seal either way. IMO the only time it would really matter is if your doing open lid inoculations, especially g2gs, where you might be working around jar with the rings off but even then it's still a matter of preference between a sturdier lid a lid that's easy to remove.

I wouldnt say its a real task. I hang the pillow case for three hours, then its usually at a perfect water level (or very close). That being said im gonna try other methods myself. But it is a very efficient way to pastuerize BULK sub.

Do some research on "Bucket Tek."

Im not having too much success with it... but then again im having way too many variables.
people are saying thats its very contam resistant to germinating spores, and this seems very accurate in the aspect that i had a bucket that seemed to be holding up very well just sitting there (5 days or so old). checked on it today and saw trich growing on the spoon i was using to scoop up the sub... not the coir (yet). which leads me to believe the spoon was the culprit all along... got 12 jars colonizing so im thinking of doing half them bucket tek, and just dumping all the sub in without a spoon to help. the other half ill pasteurize some other way.

Work with your hands then-> latex gloves, tyvek sleeves, lots of bleach,fresh clothes and isopropyl. Bleach out bucket and tub, make sure no air currents in the working area. You know...
