Hum. Thanks everyone for the input. I grow hybrid catts under a MH
light (on a 14-hour-day) timer and in a south-facing window. In summer,
they go outside from June through September. So, perhaps they are not
getting the dry winter rest and short days that they're wanting. I will
do a little research. It seems as though my catts either bloom like
crazy or sulk. Perhaps the sulkers need a different treatment.
