Pasteurization Problems
    #18774723 - 08/29/13 07:29 PM (10 years, 4 months ago)

I seriously can't pasteurize on my stove. I just wasted 19 jars of hydrated coir, etc because my stove likes to cause giant leaps in temperature out of nowhere. It takes insanely long to climb to 145, and as soon as does, it jumps up to 180 or so out of nowhere and refuses to drop. Has anyone else had this problem? Did you find a workaround?

I use an oven roaster that you get at walmart.  It still takes forever but I dont have to stand over it.  4 hours for the first batch 3 hours for the second batch.  I can do 10-12qts per batch.

what if you ran two or three roasters at a time??

you could do twice or three times as much?


do you just fill the roaster with the sub and set the oven at 160?

I set it at 155, the thermostat is a bit off.  I used a candy thermometer for the water and a meat thermometer for the sub for the first couple of runs.  You could use more roasters if you so choose.  They aren't that small I don't have the space.

so are oven roasters almost like a double boiler?

pretty much.  But with a heating element running underneath the whole thing.  It even comes with a tray so you can elevate further from the element.

and you say walmart has them??

whats the price tag on them?

im going to need to get me one of  those.

i like franks proper pasteurization tek but i dont like the fact that i have to use jars i feel like i would need a good 12 qt jars to pasturize enought sub for one 66qt tub

and if i could just fit enough sub for a 66qt mono in one roaster it seems more logical to me.

yeah, I got mine for $20 for a 16qt roaster.  I use gallon ziploc baggies with no issue, 1 baggie can hold up to 4qts of substrate depending on how "fluffy" your sub is before it goes in.  Still use a meat and candy thermometer your first few uses (the 2 combined are like $6 or $7) because the heating element is cheap and the temp gauge on it is not that accurate, you dont want to sterilize.

Also with the baggies I can fit 3 across, and again depending on your sub will determine how much will actually fit in the bag.  I know it sounds weird but different verms seemed to make an impact at how much I could fit, either that or I smoked too much and fucked up my ratio.  Either way I love my roaster, that and my dehydrator are the best investments.

Oven is bad, as the outsides are pasteurized or cooked and the inside is just warm.  I'd do the bucket tek instead.

TBH, if you are using coir, you can get away with a bucket tek, or even sterilizing has worked fine for me in the past!  I as well as many old time growers used coir as a casing layer, and we always sterilized coir for a casing.

Would I recommend it?  No.  But you _can_ get away with it with coir.  Manure?  Please don't.

Years ago we use to use a pillow casing, submerged in water, inside of a cooler to pasteurize.  It's really not rocket science.

Its not in the oven.  Think of an electric double boiler and that's what an oven roaster is.  Its a common confusion, but trust me this is just as easy as bucket tek as it will hold temps.  For proper pasteurization you need 2 things; the ability to hold temperatures in the 160-170 range for 1 hour and then a rapid cool down in a sterile environment.  You can't get that with bucket tek, sure you might get lucky but thats all it is. This can be proven mathematically using Newtons model of cooling.

the first time i did the bucket tek was my first run at bulk
and i got trich which has kinda scared me to use the bucket tek again

Just turn the heat down when it reaches 135 degrees.  let it climb in temp from there and let it go for 90 minutes
just don't let it get below 140 for 1.5 hours.

People who get bucket tek are just lucky, there is no way mathematically possible you can get coir to hold the temp before it cools down.  Coir is naturally contam resistant but that doesn't mean it can't.

Guess I am lucky :shrug:

I have done the bucket tek over and over with zero issues.

You want to call that luck I don't mind! I am a pretty lucky guy :grin:

Nothing wrong with luck, there is some needed in this hobby.  But you can't argue the laws of physics and mathematics.  For the bucket to properly pasteurize it would have to break the laws of thermodynamics and Newtons model of cooling.  If that bucket were to do that it would not be sold for $3 at a hardware store.

I have a bag of wet coir that ive stored now for 8 months without a spec of mold.  This was done with my pasteurization method.  If it was poo that wouldn't likely happen.  Coir is just very forgiving, that's why I stick with it.

Yeah I don't think I'll ever even bother trying poo. Coir is so easy and definitely performs well enough for me. What more could you ask for?

Something i have been curious about lately is why some people have success with the bucket TEK and some don't. There has to be a reason as I don't believe in luck. I colonize and fruit my tubs at 68 degrees. I may try to stick a tub in a back bedroom and close off the air vents so the temp gets on up closer to 80 and see what happens.

We don't know their home conditions, what they did with that bucket or what crawled across that coir on the way to where they bought it. Too many variables, if you get the green then you will have to move on, cuz I heard it's a bitch to shake off.

And bacterial issues usually come from spawn.  Good sterile procedures and good inoculation sources see to the reduced odds in that regard.

You've done multispore but don't believe in luck?  :mindblown:
