Drainage is good!How is your drainage? I just read that overwatering with poor drainage may cause root rot, which could manifest itself with dropping flowers and stems
Its normal - anytime things aren't just quite right a Chinense (and any pepper I suppose) will cast its flowers and the stamen that connects it to the plant off.
too much or little fert, too much water, wrong temps, and bad hairdays all can possibly cause the flowers to drop.
they will set when the plant is ready though, and you'll have fruit in no time
It's fairly common for plants growing indoors to drop some of the flowers. I use two fans and my plants whip around pretty good. If pollen is produced the flowers tend to stay and their stems thicken, but if there's no intro to pollen a flower has a window that closes pretty quick. Long light cycles and high humidity can also effect the results. The plants need to rest and I've noticed better results when there is a total dark period everyday in the grow area..........just my opinion
