yeah dude. some people are just strong headed. I dont know about you but I know people who are absolutley hate the idea of flushing, they think its a bull shit myth and some of them even get offened when all you wanna do is just take a shot at it and try (sadly my room mate acts this way) and those are the people that bug me. The ones that gatta not just give you their opinion but make it all personal like "well your just dumb if you do that" and they can't except that some people are more open minded than them and see this whole hydroponic growing thing as a very fun and exciting way to exercise the scientific method as I do so I just do what I do and try to be as friendly as possible about it. This guy your describing seems like the kidna doosh that acts like its his way or your an idiot. Screw that close minded bs.
but yo im happy I met you we need to talk more im sure we have much more to learn from each other!
