Should the soil be sterilized before growing cannabis?

My wife did it once a long time ago trying to kill fungus gnats, lol.

But It's your soil man. Do whatever you want. Personally I don't cook my soil, but to each his own.

I say torch it.
The bagged soil was not the biggest concern, my reusing the coco that had aphids was. But since the oven was warm...
 
i used sand to get rid of those little soil flies. a layer of sand and heat lamp close up shining on the sand. simulated a desert for a bit and they went away.
I didn't want the sand in my coco. What is the point of using it if fresh air had a layer of sand to go through?
 
No really.
