I just fermented a helles back 1.064 og with wlp 820 at 55, it took off quickly. Taste before cold crashing was clean, no fusel alcohols or other of flavors. Going to keg today. Point is, if it's sluggish at 50- warm it up a bit. 50 is on the low side door this yeast per white labs.

I always do number 2... About once a day. Also, I cool to as low as I can with ground water, then chill in fermentation chamber to pitch temp (also number 2).
