My Substrate Pasteurization Method using Crockpot
    #17529462 -

I picked up a slow cooker at a thrift store last fall and have very successfully used it to pasteurize bulk substrates for the last few grows. It's a Hamilton Beach model with a temperature probe that heat the contents to a predetermined level and then powers down into a cooling mode.

The recipe I use makes about 8 quarts when packed into the crockpot:
1 half brick Coir (hydrated)
1 quart verm
1 quart composted horse manure
1 cup gypsum

I mix up the substrate in the evening and then set the cooker on probe mode to heat the mixture to 150 degrees. It takes about 3 hours to reach the required heat and then I unplug the machine and let it cool overnight and mix up the spawn into a monotub in the morning.

Three monotub grows have been completed using this method and all have been contam-free for at least two full flushes (I usually don't bother with a third). The cooker sells for about $60 new, but I got mine used for $20.

I just wanted to share what has worked well for me in small grows without bothering to fill jars and fire up the ole PC.

I've always wanted a 'set it and forget it' pasteurization method, it's so time consuming. I did finally find a way to do it, I just put my stove on a very low number like 3 (1-10 is settings) and the pot of water reahes about 165F and holds there permanently. I just toss jars in the water and come back in a few hours, it takes about 1hr for the core temp of the substrate jars to reach the temp of the water 165F.
This is good information and I thank you for sharing with us.

Op I like your slow cooker method. Mine gets too hot, and has no control on it. Id have to get one.

Here is something i came up with some very granular control.


Tm I got your back.

Get:

Pair it with:

And put it on a timer.



Set your pot on the burner, and crank it up to the hottest setting. Put the probe from the controller in the pot.


You will have to time how long it takes to get the pot up to temp on the first run, so you can program your timer accordingly.

I just looked up the exact model I've been using in case anyone is curious. Here's the link:
http://www.amazon.com/Hamilton-Beach-33967-6-Quart-Programmable/dp/B001AO2PXK/

It's actually fairly cheap online but obviously isn't absolutely necessary since I already have a PC. I just like not having to deal with the extra step of loading and unloading jars of substrate and having to watch the temperature level during a traditional PC pasteurization method. This is very much a set and forget system. It does take a very long time to cool down since the stoneware container is designed to hold in the heat but by morning the mixture is generally close to room temp.

I mix all the contents into a single monotub with three quarts of Rye or WBS spawn prepared using the process detailed in RR's DVDs which gives me about a 1 to 2 1/2 ratio. Anywhere from 2-4 weeks later it's ready to go into fruiting and I got lbs of nice fruits. Now if could just figure out what to do with them all!
