I have both going right now, along with 3BOG and White Crack, and Stone Dragon. My poor carbon filter has met its match, and is failing miserably at the moment. I am not sure what one is causing the most stank, but it is noticeable. Turned my variac up to 65% on the fan/filter, so hope that stems the tide for another week or so. I never had 5 mature plants going before, so that might be it. I have had 4, but it didn't smell like this.
Ghost Toof up close has a sour/fermented fruit smell. I know this because I compared it to 3BOG directly. 3BOG is a more classic soft fruit aroma. Sweet & Sour also has a fruit smell, not sour like GT, and not as fruity as 3BOG. Hard to explain, maybe not as sharp as 3BOG. If you were only growing one or two, I would think you should be ok. Just my $.02.
