Gorgeous plants, fantastic photography, and overall exceptional journal. Top notch on all fronts
Good idea on the fan controller, but I would hesitate to hook it up to the timer. You know your room better than I do, but I wouldn't dim the fan too much at night, unless your humidity is REALLY low. I know you said you turned your humidifier off, but just throwing it out there. Humidity rises at night, and pockets of stagnant moist air could be deadly to those gems you have on your hands. From my experience this winter, these autos are unbelievably tolerant to the cold. It actually brings out the colors more on the strains I'm running.
Anyway, keep it up. Poised for a flawless victory.
