Improved Bucket Tek (Bucket PASTEURISATION)

I have recently made some improvements to the bucket tek. With these modifications it is now quite easy to maintain proper pasteurisation temperatures using a bucket. This tek will pasteurise enough substrate for a 66 quart mono.

You will need:
1 - 650 gram brick of coir
2 - Quarts of vermiculite
1 - Handful of gypsum
2 - 5 gallon pails
1 - Meat thermometer
1 - Plastic lid
2 - Large pots for heating water
1 - Sleeping bag or thick blanket

I had not originally planed on writing this so I do not have pictures of every step at this point.

Place one brick of coir into a 5 gallon pail and break it up using a knife or flat head screwdriver. If you stick the knife/screwdriver into the side of the brick you can easily pry the layers apart. Once the coir is broken up add 2 quarts of vermiculite and a handful of gypsum. Then mix it all together well.

Take two large pots and fill each one with 5 quarts of hot water. Place them an your stove and turn it to high. Use a meat thermometer to monitor the water's temperature. When it reaches 170 remove it from the heat.

Pour the water from pot #1 into pail #1. Then place pail #2 into pail #1. This step will help your substrate maintain its temperature threw out the process.

Now pour half of the water from pot #2 into pail #2 and mix it in well. Now add the other half of the water from pot #2 and mix it again.

At this point the temperature of your substrate should be in the mid 160s. I like to check it in the center and on the outer edge of the substrate.

Now set a timer for 1 hour. Put a lid over the top of your pail and wrap it in a sleeping bag or thick blanket.

When the timer goes of open your pail and check the temperature again if you did everything correctly your temperature at the outside edge should still be above 140. You can check the temperature in the center as well but it will always be slightly higher so there's really no need.

Take off the sleeping bag and lay the lid on loosely while it cools for several hours. Once cool you will still want to check the moisture content before you use it. Mix your substrate well and pick up a handful. It should be somewhat fluffy and no water should drip from it. Give it a good squeeze and a small short lived stream should drip out. If your substrate is to wet just squeeze out the excess water.

well so far so good. these are the two subs I made using this tek for the first time.

I have now used this method several times with different amounts of substrate. I have also used it with additives like coffee and manure. So far so good.

A few people have now successfully used this method with manure.
