Scientific research showed that plants not only emit chemicals under stress, but specific chemicals can be discharged in response to specific stresses. When attacked by threat "A", they can emit a chemical that attracts a predator of threat "A" in response.I'm starting a new line of deodorant for stinky plants. Not sure what Ima call it yet. Was toying with HogSpice. What do you think? Sound like a winner?

Laugh all you want about the "happy plants don't stink" statement, but science has shown there could very well be some merit to this belief.
