For alot of dope i get better growth from 20-4 than i ever did at 24 continous. Mike have you even tried 20/4? There are things a plant is programmed to do when the sun sets. It waits until dark for some processes to gain priority. I'm not talking out my ass either, my plants are more robust and definitely with out a doubt grow noticeably faster with 18/6 and 20/4 vegging light cycles.
Maybe you should try it, cuz i have a feeling you havent....
For Tenere, i have grown sativa dom and pure indicas side by side, and while there probably are slight differences in ideal conditions and nutrients, I've basically grown them the same. You still target ( in flower) for 24 degrees Centigrade, 40-50% humidity, 6.5 or so PH, get some air moving....these things are always a constant, and if you get them right your more or less guaranteed some dope!
Good luck!
