Hello All,

I kinda do the same thing with potting soil and my home made compost. I went to the dollar store, picked up a few large aluminum roasting pans, covered and threw them in the oven until the temp reached 185 deg F. So far, so good.

I bake commercial potting mix in an oven at 220 deg F (roughly 105 deg C) for 2~3 hours to kill fungus gnats & their eggs.
