Quest for mold-resistant strains, Hawaii outdoor greenhouse grow

Does anyone know how low-stress training (LST) affects the roots?

I'm not an indoor grower, and I've never done LST, but it would make sense if you were using small-ish pots and trying to get a great harvest, if LST slowed down root growth or made the root ball more compact in the container, thus avoiding a root bound condition. I read today that LST makes the roots grow more laterally.

It makes sense that a smaller canopy achieved by LST would require a smaller root mass to support. Is it true?
 
Greetings Growmies,

I added day length and night length (hours). As would be expected, day length follows the solar angle. Curiously, the longest days of the year, 13.43 hours, June 14 through June 26, don't correspond to the max solar noon angle of 90°. It turns out this is because the sun angle goes beyond 90° between May 26 and July 15. In other words, 90° is straight overhead, and beyond 90° is tipping to the north. Most of the year, between July 15 and May 26, the sun angle is to the south. I have adjusted the angle when it goes beyond 90°, shown in pink, and included the June 20 solstice when the angle is at its maximum.

key:
angle=angle of the sun at solar noon; time=time of day at solar noon; day=day length in hours; night=night length in hours; *=solar noon angle at 90°; *=max solar noon at solstice; *=solar noon angle at its lowest
 
The middle of the "solar summer" is June 20, as opposed to the middle of the "astrological summer" which is August 6.

Who cares about the astrological summer?!!

For my whole life up until now, I've been in the dark about solar summer! Gregorian calendar programming! The pagans called the summer solstice "midsummer".
