Holy crap.
That was exactly what I was looking for knna. Not that i can claim to fully understand it all, lol.
Thanks to you too, alteredego, that was the other piece to the puzzle.
So I think I've got it, but if someone doesn't mind double checking me...
Optimum Growth Conditions:
1200ppm Co2
82 F LEAF TEMP, DAY AND NIGHT*
60% RH **
* During stretch, anyway. The obvious implication here is that in order for the plant to see a consistent temperature day to night (and therefore minimize stretch) I'd have to run a space heater at night, and probably shut off the A/C. Both are possibilities.
** RH should probably be backed off, and possibly lights raised too, toward the end of flowering, especially if additves (Bushmaster and Gravity come to mind) are used that will increase bud density and promote mold growth.
