... not so much low RH, though that's fine for mold prevention, BUT don't run the RH that low, the plant may stress, last thing you want prior to harvest; 30's% is better... it doesn't increase the number of trich's, new ones aren't forming and maturing that fast,.. it's the concentration of terp's mainly, not necessarily the cannabinoids that elevates,.. keep in mind, it's the terp's that affect the nature of the buzz a great deal, and richer content of them can make bud kick harder, like it's more THC in there when actually, it's the terp's,...
Terp' content is highest generally, first thing in the "morning",... more true for outdoor plants than indoor,.. outside, the Sun, temps, wind all take their toll on the terp content, especially low molecular weight terps that volatilize easily,... they replenish during night... dark period prior to harvest is taking this a step further, basically extending this rebuilding time,.. plenty of controversy behind this! But as an OD grower, I know for an olfactory fact, my plants are best smelling taken mid-morning, after a extra day of dark time,... going longer than a day or so is vastly diminishing returns, and really risks mold promotion, so if you do dark periods, make damn sure the air movement, RH%, and temps stay within optimal ranges,... Mold loves cool, dark, and still!
