you shouldnt have to, you can PC them or use the oven, usualy 400F for 1.5 hours is sufficient

I spent alot of time rinsing all the fine "dust" out of my lava rocks in the 18 gallon container I planned on using for a fruiting chamber. I then brought about 2 gallons of water to a boil in a stock pot, and poured it over the rocks (in the 18 gallon tub)just enough to cover. I let that sit over night, and added about a cup of bleach.

I let that sit for an hour or two, and then rinsed again.

Now, I wish I would asked this question before doing all that. Putting the whole thing in a roasting pan/baking dish, and bringing it up to sterilizing temps, would've been ALOT easier.

Rinsing the rock, however, was a good idea, there was a ton of fine particles and dust.

how about lining a baking tray/cookie sheet with aluminum foil, then puting the rock on top?

There seems to be 2 camps, here at the Shroomery.

1. People who sterilize... EVERYTHING !
2. People with a more "laissez-faire" attitude concerning sterilizing.

It appears that the people who complain about contamination, mostly belong in Camp 2.

The person that I speak for, is only on his forth grow. But he "goes the extra mile" with regards to cleaning. He has not had a problem.

Well.. all that you are putting in the grow chamber are colonized substrates... It isn't really necessary to sterilize the lava rocks. A good heavy rinse or two should be enough. Never heard of sterilized perlite or lava rocks.

Yeah don't waste your time sterilizing the rocks, that's ridiculous.

Wash the rocks, pile them onto a pizza pan, put them into the oven 350-400 for hour and half, put in tub, and mix a light solution of h2o2 and o2 and your ready. left out some other stuff but should be a good start.

I only soak in bleach water overnight, then rinse really well.

I soak my geolite in bleachy water...

then rinse them in fresh water.

no need to cook or pressure cook anything.

bleach will kill almost anything...we deal with.
