Here's an idea...

Right now I'm living in an attached back house on someone's property that they turned into a studio. My landlord is cool with me toking up, he just prefers I do it in the bathroom since he can't smell it from there.

So here's my question: I'm thinking about hotboxing the bathroom. I've never tried it before, but it's pretty small so I may be able to pull it off. Are there any special ways I should go about sealing the room?

just seal it with whatever you have, don't turn the exhaust fan on.
