Yea pressures put on the plant, but it's got to be done very deliberately, if not it could have the opposite effect. Too much stress is a bad thing, but certainly different "physiological responses" can be expected, to certain stimulus, or something that allows the plant to adapt better to it's surroundings. It's great when it's synergetic and opening the floodgates to growth, or a huge impact, but it doesn't necessarily have to have that effect. Personally, I think spider-mites might actually enhance resin production, but it's also got a lot of negative issues also, if something, anything that can be harnessed for enhancing or selectively controlling oil productions is another tool in the box for creating genome expressions. Done over several generations, these adaptations become part of the genetic coding, and you've created your own little contribution to diversifying the cannabis cultivar.
The levels and specific ratio's of UV light we are speaking about here is far from what would be observed in nature, maybe in some of the equatorial regions possibly. Anyhow, it's just theory based upon taking a phenomenon observed in nature and tweaking it to it's most extreme an useful conclusion, much like CO2, or Hydroponics.
Should be fun, I love geeky shit.
