Nice job calling a moderator an idiot. We have a no flaming rule. The last one you want to flame is me. While I called your idea ridiculous, I never called you names.

Next, still that's not going to work. Now you have unfiltered marijuana smoke flowing out to public areas. How many times do you think you can do this before people figure out which window the marijuana smoke is coming from or before they see the hose? Then you still have the smoke coming off the bowl, bong, joint, etc. filling the inside of the apartment.

Still a bad idea, with or without water.

Is this how you get away with smoking in your parents' house?

Letting the marijuana smoke out of your window through a hose seems like a good way of getting a search warrant with your address on it.
