Anyone ever tried using cold frames for solarizing potting
soil to kill pests such as fungus gnats? Seems simple
enough, just pop the lid and toss in a bag of soil for a
week or two.

I can reach killing temperature in dead winter. Summer temps
should be near boiling pt of water, especially if wet and
sealed in a plastic bag.
