Actually, temp does offer a contribution to harvest. When the 'night' temp is 15' or more lower than the 'day' temps, the plant is tricked into more vigorous flower production, believing that fall is here, and winter is close. Another way to help bolster this floral misconception is to add some red light to the setup. This comes automatic with HPS. I adjust(with my bluer MH) by adding bright red reflectors.
Variations, vaguries, and chance are what makes home growing such an enjoyable challenge.
Of course, it all starts with genetics, which can make or break a grow. From there, maximizing lighting, temp control, CO2 introduction, types of ferts, pH of H2O, and frequency of application, and control of these potentially vital variables are what makes a staisfactory harvest. Oh, yeah, another important issue: patience and restraint.
