Holmes on Homes tv show with Mike Holmes repaired a house that had indoor harvest of marijuana plants.
The police before the repair had raided the place after the crooks er... farmers tapped the high voltage lines for the grow lights and the power company noticed.
I remember that episode. All the drywall and insulation had to be replaced and the wood framed walls had to be sandblasted (with walnut shells if I remember) to remove the mold growing on it. A landlord’s nightmare.
