water into a bucket with a brick of coir and two quarts verm.
about 15 min into it i mixed everything up and stuck a candy thermometer into it.
an hour later i check and the temp was still around 150.
would this be considered pasteurized?

If it was between 140-160 for an hour then yes, I just have a hard time believing that after an hour + opening to mix your temp didn't drop at all.

well my bucket has a good seal. and the candy thermometer read around 47 when i last opened it. i opened and mixed everything around and it was still really hot for me to handle so i did the best i could stuck the candy therm back in.
that was like 15-20 mins ago it currently reads 125 but thats because i cracked the lid after fluffing up the sub.
i might add that after the first initial mix i packed down the sub as much as possible so it retains it heat more.

As long as you keep it between 140-160 for an hour you've pasteurized your substrate.

I guess I don't know what else to say. I've never had the problems with the bucket tek that other people have. If you hold temperatures then you're good. After the hour break the lid and mix it up to help it rapidly cool.

Umm... so... two things:
1. It takes coir about 30 to 60 minutes to fully hydrate when in a bucket with water. Until it's hydrated, it won't really be pasteurize-able because it won't conduct heat. So, no, even if what you posted is true, I don't believe you could accurately say you had pasteurized your substrate.
But, more importantly:
2. What you say happened is impossible unless you're leaving out some important details. I'm guessing you used about a gallon of water? So that's about 8 pounds of 150-degree water. And you added it to about a pound and a half of room-temperature substrate. Even if your bucket were perfectly insulated, the overall temperature can't end up at the same temperature as the water -- the water cools some as it warms the substrate. I suspect you need to re-examine how you're doing your temperature measurements.

well the coir was hydrated when i mixed it and the temperature read around 147 unless it was 137 at an hour.
no details are missing. so yeah.
and okay thanks so its not pasteurized then.
ohwell im going to throw 5 quarts of colonized wbs and see if it will fruit contam free.

second run at trying to pasteurize in a bucket.
Prep Work.
Took a brick of coir. grated it down to a fine dust with a cheese grater so it would hydrate quickly. added two quarts verm. (fine verm)
took 5 quarts water. heated to 175 degrees let it drop to 162 before dumping in bucket.
mixed and packed down coir as much as i could. (it was hard since it was hot.)
check temperature an hour an a half later with digital thermometer read 142.3
im guessing ive successfully pasteurized in a bucket.
right?

2 hours after just checked temperature again.
137.

I bust up my bricks by prying with a screwdriver.
5 quarts of water may be a little too much. I use 4 quarts per brick and half quart water per 1 quart verm. But I use medium verm and you use fine, so it may be different.
If the entire substrate got up to 140-160 for 60 mins, then it could be said it's properly pasteurized.
I can't say this happened unless you checked in various spots. I suspect the outside cooled faster than the middle.
If part of it got too hot, that's okay, because it's about the core temp. But if the outside didn't stay up to temperature, then the water didn't likely kill much.
Also, rapid cooling is a key component of pasteurization. A mass that size does not cool rapidly, as you see by your measurements.
It still may be useful because its CV, but it may not be properly pasteurized. 
I didn't want you to think I was being a dick on my other thread.

Bucket tek is not proper pasteurization.
But since it is coir, it will be fine I bet.
Don't mistake bucket tek for proper pasteurization, ever.
Proper pasteurization evenly heats the substrate, holds the core at a precise temp for a precise amount of time, and cools rapidly after the 60-90 minute time has passed.
The bucket tek does not do any of this, and it complicates matters more because it heats the substrate very unevenly.
But again, it works good with coir for most people.
PS. If your water was at 150, it would not hit 150 in your substrate. Your thermometer is probably crappy.

While the bucket method is not ideal, as long as you get all of the substrate within the correct temperature range and keep it there for 1-2 hours, it will be pasteurized.

Not true.
If this were the case, we'd all be pasteurizing our coffee and horse manure in a bucket.
It works with coir because coir is naturally contam-resistant.

If you love the bucket Maybe you should fuck it Or...... Use the right contraption To practice pasteurization
The bucket tek is a 6th grade project. And i dont give a shit if it works. Fucking a hooker will release a nut, but there are better ways. Get serious guys and expand yourselves.

The 90's. Ha ha. That's awesome. For some reason, I don't get offended, but I do offend. Not my intention though. Guess my point is, if you want to do menial things with your life, like the bucket tek, then do it. But please do us all one tiny favor and not ask questions about it.
