I'm still in a red state. With that being said, there's been so many technological advancements made in the last 15 years that growing clandestinely is not the challenge it once was. I started growing in 2008, so this is after carbon filters came out.. But man I couldn't imagine growing without one like @stiickygreen
I do remember back around 2009 or 2010 having a lady friend over who knew I smoked weed, but didn't know about me growing it. She walked into my house and was like "it smells like you smoke a lot more weed than you told me you do", hahaha. Ever since then I've become a lot more careful about growing, l live in a different house nowadays, and my garden is in the basement now. Helps a lot with odors, such as when you're trimming or when the tents are open.
One thing I think of a lot is the network of friends I've created. If my furnace takes a crap on me, I can't call 1-800-Furnace, I have to call my HVAC buddy who's in the know of my garden. Same thing goes for other random shit, like plumbing, electrical, or even getting new windows. I'm real cognizant about who I'll let into my home.
