HAHA That's a perfect idea!Its not illegal to grow tomatoes is it? Tell them it was tomatoes. All the evidence is destroyed right?
Normally an Investigator from the fire department will try to determine where the fire started. If there isn't any indication that it started in your grow room -- don't say anything about having a grow room.you cant prove the grow didnt start the fire causer everything is burnt up and they will find a reason to deny your coverage because as soon as you say that "My grow didnt start the fire" you are toast
