Ok here what i am going to do i just rearranged my setup to fix the smell issue. I live in a 2 story townhouse and my op is in the spare bedroom closet. Closets cause tons of issues especially since i am only renting. So i took my setup out of closet and moved my clothes back in. i took my dr60 and located it over by the window and placed some cardboard up (temporarily). and am now exhausting outside. Immediately my tent, when closed, sucks in. Is that a good thing? I also need some pointers on what would be a better, more discreet, thing to cover a window up other than cardboard? This product will also need to be able to handle rain and the wintry months. I am thinking of just covering the cardboard with some panda film, not sure if i want the white or black side facing out. could def. use some recommendations at this point.
