Just recently purchased a Fogstorm 700 to use in a garage haunt this year. Is there a significant difference among these fog fluids (ie. in density, dissipation, shelf life, etc)?

Also, has anyone tried using the Sinister Scents Forest or Rainforest additive? I'm planning to do sort of a mossy, jungle-like cave scene and the scent additive sounds really cool!

Thanks!
