Has anyone heard of this before? Apparently this researcher found significantly increased growth rates by applying ~1 ppb of H2S.

Isn't the odor from C Plus or Photosynthesis Plus hydrogen sulfide? I love it! Nothing like the smell of C Plus in the morning :cool:

Wow, whoda thunk? My only previous knowledge about H2S is from the oil and gas industry, and the warning sirens near wells warning of toxic emissions. The shit is seriously deadly!

The concentrations used in this experiment suggest that the treatment is harmless in terms of impact on edibility. So how can I get 1 or 2ppb (parts per billion!) Into my veg tent?!
