Seriously? Weed plants smell, some a lot more than others in veg, u are making a lot out of NOTHING.If your plants stink, they are pissed off and you need to figure out what's wrong and fix it! They shouldn't start emitting an odor until well into flowering.
Some basics,,,,,
they don't like the light too close (contrary to what you read in forums)
they prefer a mixed spectrum (blues & reds) HPS alone does not do this though some HPS bulbs have been made to include a bit of blue
they don't like to touch each other
they prefer a balanced nute regime
they don't like negative pressure (caused by sealed environments & fans pushing and pulling)
